Here is some description of Aniline Wax Pull-up leathers:

Wax pull-up leathers derive its color from dyestuff and effect wax that gives the leather a lively distressed look. When this leather is pulled, stretched or scratched, the waxes dissipate characteristically and become lighter in those areas. Sunlight and stretching through high wear areas are two main indications that the infused wax needs replenishing. As is, effect wax behaves just like the primary fatliquor they do diminish through ageing and will need periodic replenishing. Besides contributing to the color intensity, it improves in water shedding effect. Effect wax when applied to the leather penetrates while some transforms into fine cloudy crystal and remains on the surface. The dried surface white powdery deposits are then heat activated and when they melt, they coat the surface with a glossy sheen. In a restorative care cycle a urethane gloss topcoats is applied to restore its original appearance. In every of these kits there is a bottle of EffectWax-8.6 to work in conjunction with other system products in a holistic approach for maintaining or restoring this unique characteristic only to aniline wax pull-up leathers.

Leather Doctor® Kit-Aw3, aniline wax pull-up leather care kit is an innovative leather-safe (pH 3 - 5) system designed for keeping leathers at their highest level of appearance, maintaining its pH chemistry integrity, enhancing their suppleness and prevents premature ageing. Leathers that faced the sun, closed to fireplace and heaters dries out the fat and oil that keeps it supple sooner than the non-heat exposed areas. The diminishing of the fat and oil through evaporation results in the leather fibers being stick closer together that results in stiffness and when flexed during used will lead to cracks. Periodic use of Hydrator-3.3 to plumps the stick together fibers prior to fat and oil replenishing with Fatliquor-5.0 will keep the leather supple and strong. Thus, reduce the premature ageing of the leather against stiffness and cracking. WaxEffect-8.6 rejuvenates the structural wax pull-up effect and coagulates a cloudy waxy coating on the surface to be heat activated into the characteristic glossy sheen during periodic care. The surface wear of the leather is greatly reduced in preventive care with a rub-resistant Protector-D that enhances a non-stick draggy-feel to shield against sticky soiling, besides healing and concealing lightening scuff and abrasion marks. Periodic cleaning and rinsing with Clean-3.8 follows by Rinse-3.0 to the bare body contact areas like headrest and armrest helps reduce greasy soiling build-up. Restorative cleaning and occasional dye stains removal from new blue jeans is accomplished with Prep-4.4. Note that the mentioned product suffix number denotes its pH value in this leather-safe holistic care system for aniline wax pull-up leathers.

Kit-Aw3 comes with reduced weight option from 2kg to 0.6kg to save on shipping thus the 250ml bottles such as Clean-3.8, Rinse-3.0, WaxEffect-8.6, Hydrator-3.3, Fatliquor-5.0 and Protector-D have to be cut or filled up with distilled water prior to use.

Cycle of Care Instruction:

Preventive Care:
A non-stick, rub-resistant protection is recommended to be in place before putting the leather to daily use. Protector-D imparts a soft natural draggy-feel that enhances the leather luxuriously to the sense of touch. The non-stick surface shields the leather from sticky soiling thus prolonging the high level of appearance. Rub-resistant abilities reduce wear to the topcoat and also have properties that seal and conceal scuffing. Optional leather-scented version Protector-D+ diffuses a classic leather scent that boost the sensuous leather more appealing to the leather lover. This protection care commences before usage and at the end of each level of routine, periodic or restorative cleaning cycle.

Instruction:
1. Apply Protector-D on dust free surface after shaking well, towel spread and is ready for use when dry.


Routine Care:
Routine care includes procedures such as general dust cleaning, attending to spots and stains as required especially the neutralizing of sweat or perspiration stains from shifting alkaline. Thus prevents leather from tackiness. A routine non-stick rub resistant protection after neutralizing rinse helps keep leather in a more attractive and healthy state while preventing premature wears.

Instruction:
1. Spray Rinse-3.0 on a dust free surface, horsehair Brush-1 agitates and towel extract until it shows clean.
2. When dry, apply Protector-D after shaking well, towel spread and is ready for use when dry.


Periodic Care:
Periodic care is recommend before soiling causes damages to the finishing. This keeps leather consistently clean and healthy at all times. Body contact surfaces would require more frequent attention than non-body contact surfaces. While the headrest and armrest gets the most of body oil and sweat contacts.

Instruction:
1st phase – Cleaning:
1. Spray Clean-3.8 and agitate with horsehair Brush-1; ensuring a uniform saturation application over the entire surfaces a section at a time.
2. Towel extract until it shows clean.
3. Remaining residues are spray rinse with Rinse-3.0 and towel extract to a squeaky-clean.
4. Let dry and inspect for satisfaction, otherwise repeat cleaning process as necessary or proceed to hydrating.

2nd phase – Hydrating:
Hydrating is essential to relax unnatural creases and wrinkles. Leather shrunk and becomes stiff when the structural fibers become stick together as the fatliquor diminishes through ageing or under heat over-exposure or under influence of alkaline solution. They are stretched crosswise when the leather is plump. Plumping the stiff leathers may take up to 72hrs under evaporation control. Besides, its pH value of 3.3 helps charge the protein fiber ionic positive (+ve) to increase the hydrogen bonding attraction between the ionic negative (-ve) fatliquor at the molecular level.
1. Spray Hydrator-3.3 control and spread with foam brush to hydrate deep into the leather thickness.
2. Let dwell 10 to 30 minutes to break surface tension, depending on severity of dryness, with optional plastic cling wrapping to control evaporation for a longer dwell time up to 72hrs, to plumps the leather more effectively for ease of cross stretching unnatural creases and wrinkles.

3rd phase – Fatliquoring:
Fatliquor evaporates as VOC (volatile organic compound) when temperature rises especially from exposed micro crazing and stitching rows. Periodic fatliquor (ionic negative (-ve) charged emulsion of natural fat and oil) replenishing maintains the leather’s structure integrity and pliability thus increase leather tensile strength with softness and added intensifying color richness.
1. Spray Fatliquor-5.0 after shaking in like manner as Hydrator-3.3 and let dry naturally.
2. Repeat application while still damp about 25% moisture content remaining in between drying until saturated again.
3. Leave the leather for slow natural drying for extra softness.
4. Wipe surface strays with Hydrator-3.3 to free of sticky residue.

4th phase – Preventive Care:
1. When dry, apply Protector-D after shaking well, towel spread and is ready for use when dry.


Restorative Care:
Restorative care is the ultimate corrective or salvage care system that removes accumulated soiling including aged conditioners to its original OEM finishes. Accumulated soiling that fills creases is often mistaken for cracks. Restorative cleaning is performed by Prep-4.4. It works by chemical reaction to emulsify soiling through its penetrating, lubricating and suspending power. Its thick as honey viscosity facilitates coating the surface for effective dwell time. Horsehair detailing Brush-1 is recommended to worked into heavily soiled areas sufficiently to avoid excessive agitation that might damage already weaken finishes especially on heavily used areas. For extreme cases, the Prep-4.4 can stay continuous for up to 72 hours to do its work safely including ‘reverse transferring’ of unwanted dye stains from new blue jeans, newsprints and ballpoint ink.

1st phase - Restorative Cleaning:
1. Apply Prep-4.4 and agitate with horsehair Brush-1, ensuring a uniform application over the entire surfaces a section at a time.
2. Allow a dwell time of 10 to 30 minutes or before it dries prior to towel extraction until it shows clean.
3. Sticky residue is removed by Clean-3.8 with gentle brush agitation and towel extraction until it shows clean.
4. Remaining residues are spray rinse with Rinse-3.0 and towel extract to a squeaky-clean.
5. Let dry and inspect for satisfaction, otherwise repeat Prep-4.4 with Towel-T5 for a ‘reverse transfer for dyestuff stains, application with a longer dwell time as necessary and check for reverse transfer satisfaction. 6. Proceed with Hydrator-3.3 after Rinse-3.0 and satisfied inspection.

2nd phase – Hydrating:
Hydrating is essential to relax unnatural creases and wrinkles. Leather shrunk and becomes stiff when the structural fibers become stick together as the fatliquor diminishes through ageing or under heat over-exposure or under influence of alkaline solution. They are stretched crosswise when the leather is plump. Plumping the stiff leathers may take up to 72hrs under evaporation control. Besides, its pH value of 3.3 helps charge the protein fiber ionic positive (+ve) to increase the hydrogen bonding attraction between the ionic negative (-ve) fatliquor at the molecular level.
1. Spray Hydrator-3.3 control and spread with foam brush to hydrate deep into the leather thickness.
2. Let dwell 10 to 30 minutes to break surface tension, depending on severity of dryness, with optional plastic cling wrapping to control evaporation for a longer dwell time up to 72hrs, to plumps the leather more effectively for ease of cross stretching unnatural creases and wrinkles.

3rd phase – Fatliquoring:
Fatliquor evaporates as VOC (volatile organic compound) when temperature rises especially from exposed micro crazing and stitching rows. Periodic fatliquor (ionic negative (-ve) charged emulsion of natural fat and oil) replenishing maintains the leather’s structure integrity and pliability thus increase leather tensile strength with softness and added intensifying color richness.
1. Spray Fatliquor-5.0 after shaking in like manner as Hydrator-3.3 and let dry naturally.
2. Repeat application while still damp about 25% moisture content remaining in between drying until saturated again.
3. Leave the leather for slow natural drying for extra softness.
4. Wipe surface strays with Hydrator-3.3 to free of sticky residue.

4th phase – Preventive Care:
1. When dry, apply Protector-D after shaking well, towel spread and is ready for use when dry.

Leather Doctor® Kit-Aw6.tc, aniline wax pull-up leather topcoat refinishing kit is designed for after degreasing in a holistic approach. Most penetrated stains from the head and hands that show a darkening effect have its topcoat probably deteriorated by the oil, grease and sweat. Deteriorated topcoat removed during the degreasing process is refinished with AnilineTop-21G after wax effect rejuvenated. Removing penetrated soiling contamination starts with Degreaser-2.2, a waterbased (pH 2.2) multifunctional degreaser that emulsifies the greasy contamination, controls dye bleeding and charging the protein fiber ionic positive for strengthening the attraction between the ionic negative tanning agent, dyestuff and fatliquor. Deflocculated and suspended soiling is towel extracted, thereafter rinse with Rinse-3.0. When leather feels sticky or slimy it is a sign of leather denaturing, Acidifier-2.0 is used to pH balanced it to a squeaky feel when wet is a sign of healthy leather. Hydrator-3.3 relaxes stiff leathers and removes surface tension free from surface blotchiness prior to fatliquor replenishing. Original diminishing fatliquor is replenished with Fatliquor-5.0 to rejuvenate the leather for the desired suppleness when dry. Wax Effect-8.6 rejuvenates the structural wax pull-up effect and coagulates forming a cloudy waxy coating on the surface to be heat activated into the characteristic glossy sheen. Protector-D enhances a non-stick draggy-feel to shield against sticky soiling, besides healing and concealing lightening scuff and abrasion marks (optional leather scented version use Protector-D+) Note that the mentioned product suffix number denotes its pH value in this holistic leather-safe aniline wax pull-up leathers topcoat refinishing system.

Shipping weight options comes with reduced weight of 0.8kg to save on shipping thus all the 250ml concentrate ratio spray bottles have to be cut or filled up with distilled water prior to use.

Topcoat Refinishing Instruction:

Degreasing: Removing of surface and penetrated grease is essential for a good bonding topcoat, just like any other refinishing work with the same principle. However, amphoteric protein leather material is especially pH sensitive, leather pH value of 3 to 5 should be maintain at all time during the degreasing process. Otherwise, high pH value bleeds the dyestuff and displaced it with blotchiness. High pH or alkalinity degreaser denatures the leather when the tanning agents leaches out result in tackiness and in worst case sliminess. All degreasing will also dries up the original fatliquor and high pH value does more harm in drying up the leather. When degreasing existing cracks or dried leathers of fatliquor contents below 7% (read with a leather moisture meter or an equivalent wood moisture meter), it is recommended that hydrating it with Hydrator-3.3 prior to Fatliquor-5.0 first to top-up the fatliquor up to the original 14% prior to degreasing. This pre leather rejuvenating helps prevent over drying of the leather during the degreasing process that may accentuates or magnifies existing cracks.

Degreaser-2.2 is a dual-purpose formulation with a pH value of 2.2 to safely degreasing the leather surface and penetrated soiling, while charging the protein fiber ionic positive (+ve) below its iso electric-point or pH neutral or pI for an increase hydrogen bonding with the other ionic negative (-ve) leather constituents like the tanning agents, dyestuff and fatliquor.

1 - Apply Degreaser-2.2 after shaking it well, saturating sufficiently where apparent body contact soiling is evident and feather out to less body contact soiling areas.

2 – Leather Eraser-4 is used for better traction without the risk of scratching the finishes.

3 – Horsehair Brush-1 is used for stitching rows, welting, groves, creases and wrinkles

4 – Emulsified and suspended soiling is terry towel extracted until towel shows clean.

Rinsing: Rinsing the after working degreaser residue and suspended soiling is equally important for a residue free surface.

1 – Apply Rinse-3.0 agitate with Eraser-4 and Brush-1 and terry towel extract until towel shows clean.

2 – Check for any surface tackiness and proceed with Acidifier-2.0.

pH Balancing: Dye bleeding and or tackiness during the wet cleaning process manifested from unknown previous cleaning will need further pH balanced with Acidifier-2.0. With a pH 2.0 treatment the amphoteric leather protein fiber will increase its ionic positive (+ve) charge with the other ionic negative (-ve) leather constituents, restoring its pH chemistry integrity.

1 – Apply Acidifier-2.0, let dwell and before it dries towel extracted.

2 – Towel is check for sign of bleeding and surface check for tackiness.

3 – Advanced treatment is allowed for a longer dwell with control plastic covering and inspect for satisfaction thereafter.

Hydrating: Hydrating is introducing leather-safe surface-active agent to penetrate, relax and separate stick together fibers from locking up shrunk, creases and wrinkles stiffness. The leather may be dwell up to 72hrs while seal with plastic cling wrapper to control evaporation until the leather is plumped or limped or softened to be stretch or manipulated crosswise to satisfaction.

1 – Apply Hydrator-3.3 for an even appearance and fully saturated to relax out the leather structure to satisfaction.

2 – When leather is almost dry or about 25% total moisture content Fatliquor-5.0 replenishing commences.

Fatliquoring: Fatliquoring is the process of replenishing original fatliquor content up to its formal tannery standard of 14% when dry. The fat and oil encased water molecule when ionic attracted by the protein leather fiber breaks free and evaporates leaving a breathing space for natural leather transpiration to take place for seating comfort. The fat plumps the leather for fullness when dry and the oil lubricates the millions of interconnecting like hinges for suppleness without cracking when the leather is flexed from used.

1 – Apply Fatliquor-5.0 and spread for an even appearance until fully saturated.

2 – Before the leather is completely dry or about 25% moisture level more is applied until saturated again.

3 – When dry to normal used the leather moisture content may be read with a leather moisture meter or an equivalent wood moisture meter to about 14%.

Fatliquor-Free Surfacing: Surface Fatliquor-5.0 residue if any is removed with Hydrator-3.3 driving all surface residues below surface. Remember that Fatliquor-5.0 is a structural conditioner and not suppose to remain on the surface.

1 – Surface is sprayed with Hydrator-3.3 and work with horsehair Brush-1 until cloudy moisture if any turns clear.

Wax Effect Replenishing: WaxEffect-8.6 is the secondary conditioner replenishing the leather structure to impart a below surface pull-up distress effect and an above crystalline wax deposit to be activated with a heat blower or hair dryer to a natural characteristically sheen.

1 – Apply WaxEffect-8.6 after a warm-up and shake-up.

2 – Spray, spread and saturate with horsehair Brush-1 or other brush evenly producing a darkening effect.

3 – Allow an 8 hour natural drying time or until cloudy crystalline are formed.

4 – Activate the wax deposit with a heat blower or hot hair dryer to a natural gloss luster.

Topcoating: AnilineTop-21G is a waterbased polyurethane topcoat that is lightfast and non-yellowing. It has excellent flow and levelling properties, recoatable and forms a flexible film coat that gives good performing results from friction wear.

1 – Application is either with bristle brushes or fine airbrushing to produce professional results.

2 – Streaking or drippings if any is immediately corrected with a lint-free towel like Towel-T5.

3 – Sanding with a 2000grit in between coats improves the feel and touch of the finishes.

4 – Gloss builds up with additional coatings.

Protection: Protector-D is a non-film forming, non-stick scentless (optional Protector-D+ for a classic leather scent) protector that enhances a natural draggy-feel. It imparts a non-stick breathable barrier essentially to shield the detrimental effects of sticky soiling. Its natural draggy-feel protection increases the leather resistance to wet and dry rubs, thus reduce stretch, scuff and abrasion. It is also used as a scuff repairer, filling and concealing surface scuffs to improve appearance.

1 – Shake well, mist spray and spread evenly with a foam brush.

>>> It measures 94" wide, 46" deep and 31" high in the back.

We spoke about the Kit-Aw3 I believe but please let me know what I need and quantities and application directions.
Base on my sample that read:
1 – Area in square foot = 0.25gm
2 – Weights = 14gm
3 – Temperature = 20 C
4 – Humidity = 58%
5 – Fat and Oil Content = 5%

The total quantities of Fatliquor-5.0 required would be = 8.4 gms of Fatliquor-5.0 (Fat, Oil & Water).
In your case of 94” wide, 46” deep and 31” high = 50 square feet
That will require 1.7quarts of Fatliquor-5.0
As 83.33% of water content from the Fatliquor-5.0 will evaporates it will leave only 16.66% that contribute to a 10% increment of fat and oil.
When read with a leather moisture meter or equivalent it should reveal a reading of 15% when completely dry with the initial readings.

In a restoration leather rejuvenating process the average ratio of Hydrator-3.3 is about ratio 2: 1 of Fatliquor-5.0. In a periodic care process the ratio of Hydrator-3.3: Fatliquor-5.0 may be reduced to 1: 1 accordingly.

Here is the information for the Hydrator-3.3 and Fatliquor-5.0
Leather Doctor Hydrator-3.3 is a waterbased pH 3.3 leather-safe hydrator. It is a fatliquor preconditioner with multi functional abilities. Surface application is primary to check for even surface tension free of blotchiness prior to fatliquor replenishing. Structural application will require saturating to an optimum level with moisture oozing out when gently pressed between thumb and fingers. This universal Hydrator-3.3 is for all leather types including pigmented, aniline, vachetta, nubuck, suede, hair-on-hide and woolskin.
Size options are available in RTU, Fill and Conc. RTU is (ready-to-use) straight from the bottle. Fill is concentrate ratio in the same spray bottle to be cut and fill with distilled water prior to use to save on shipping. Conc is the 60ml concentrate to be cut with distilled water at a ratio of 1: 25 that makes 1.64 quarts prior to use to save on shipping.
The multi functional abilities include:
a) To check for surface tension for an even appearance free from blotchiness prior to fatliquor replenishing.
b) To plumps, relaxes and separates crushed, shrunk and stick together fibrils for manipulating away-unwanted creases and wrinkles.
c) To clean the leather of structural foreign contamination, the plump and limp leather is squeeze with towel laid between the leather and a smooth spatula or equivalent.
d) To rectify alkaline overexposure areas by facilitating colloidal water movement to redistribute the leather constituents from surrounding areas.
e) To activate the dormant dyestuff within the leather structure for color refreshing.
f) To facilitates colloidal water movement within the inter-fibrillary spaces for wicking foreign soiling particulates to resurface.
g) To stabilize, pH balance and charge the protein fiber below its iso-electric point (pI) ionic positive to hydrogen bond with the ionic negative fatliquor more effectively.
Instruction:
A. Surface Tension Inspection:
A1. Spray Hydrator-3.3 evenly and wipe with lint free towel to free of surface tension for an even appearance prior to fatliquor replenishing.
B. Stiffness, Creases and Wrinkles:
B1. Saturate the thickness of the leather to an optimum level with moistures oozing out when gently pressed between thumb and fingers.
B2. Cover up with plastic wrapping to control evaporation and let it dwell up to 72hrs for softness.
B3. Manipulate by stretching and cross flexing to relax the leather to satisfaction prior to fatliquor replenishing.
B4. With satisfaction the Fatliquor-5.0 has to be immediately replenished while the leather is perhaps at 25% Hydrator-3.3 moisture level.
C. Cleaning:
C1). A combination of cleaning while saturating the leather is done with horsehair Brush-1 on the surface and towel extracting it. Deep cleaning beneath the surface from the leather structure for liquid stain is done with squeezing the leather with a smooth spatula with a towel in between to reduce abrasion and absorbing the foreign contamination – See F below
D. Rectify Alkaline Overexposure:
D1. Saturate the thickness of the leather to an optimum level with moistures oozing out when gently pressed between thumb and fingers.
D2. Cover up with plastic wrapping to control evaporation and let it dwell for redistributing of the leather constituents from surrounding area.
D3. Observe for appearance and test by finger for tactile squeaky feel prior to fatliquor replenishing.
E. Activating Dormant Dyestuff to Resurface:
E1. Saturate the thickness of the leather to an optimum level with moistures oozing out when gently pressed between thumb and fingers.
E2. Cover up with plastic wrapping to control evaporation and let it dwell up to 72 hours for excess dyestuff to resurface.
E3. Remove plastic cover and let it natural dry to observe color improvement prior to fatliquor replenishing.
F. Removing Penetrated Stains:
F1. Saturate the thickness of the leather to an optimum level with moistures oozing out when gently pressed between thumb and fingers.
F2. Cover up with plastic wrapping to control evaporation and let it dwell up to 72 hours for foreign soiling particulates to resurface.
F3. Remove plastic wrapping, replace with tissue paper without airspace to trap stains as it dries instead of remaining on the surface. Recommend that Fatliquor-5.0 is replenished in combination at this stage especially if the leather has already show signs of cracking.
F4. Peel tissue paper when crispy dry and erase with Eraser-4 or Eraser-5 for suede accordingly prior to fatliquor replenishing.

Leather Doctor Fatliquor-5.0 is an anionic negative (-ve) charged micro emulsion of fat, oil and water for rejuvenating all leather types. It is typically used in conjunction after Hydrator-3.3 relaxing and opening up the fibrous leather structure. It softens the leather when dry with stretchability, compressibility and flexibility, while enhancing its rip tensile strength greatly. It is for replenishing the original fat and oil that diminishes thru sun bleaching, ageing, heat and alkaline overexposure or cleaning. On application, the water-encased molecule breaks free when ionic attraction takes place between the fat and oil with the leather protein fiber. The excess free water content wicks out leaving a breathing space behind for leather natural transpiration. The fat plumps the leather with fullness from easily collapsing into creases and wrinkles during stress or flex, while the oil lubricates the fibers so that they slide over one another smoothly like millions of inter-connecting hinges. Thus helps to keep leather at its optimum physical performance and prevent premature ageing. This universal Fatliquor-5.0 is for all leather types including pigmented, aniline, vachetta, nubuck, suede, hair-on-hide and woolskin.
Size options are available in ‘RTU’, ‘Fill’ and ‘Conc’. RTU is ready-to-use straight from the bottle. Fill is concentrate in the bottle to be cut and fill with distilled water prior to use to save on shipping. Conc is concentrates to be cut with distilled water at a ratio of 1: 5 to save on shipping. Thus 250ml Conc becomes 1.58 quarts of RTU and Quart Conc becomes 6 quarts of RTU.
Leather Approximate Quantity or Percentage of Fatliquor:
The quantities of fatliquor (fat and oil) contents retained in the leather after an universal tannery fatliquoring process may varies up from 14% to 16% depending on the leather types and it usage. This percentage drops as the fat and oil content diminishes or leaches through ageing, water, heat or chemical overexposure.
Leather rejuvenating or fatliquor replenishing is base on weight of the leather in relation to the percentage of remaining fatliquor. A simple calculation of percentage of fatliquor topping up requirement would be as follows:
If the weight of the leather in question is 100gm and fatliquor (fat and oil) content meter reading is less than 1%.
By applying 80gm of Fatliquor-5.0 to it will deliver an end result incremental of 13.3% fatliquor when dry as the 66.6% water contents evaporates.
In the leather rejuvenating Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 system, Hydrator-3.3 plays an important role by relaxing, opening up the inter-fibrillary spaces, facilitating and redistributing colloidal water movement, protonating and doing all the pre-conditioning work prior to fatliquoring including cleaning up any excess surface remnants to have a sticky-free surface. In practice with severe dryness the ratio for Hydrator-3.3 is 2 to 1 of Fatliquor-5.0.
It works out to be approximately 160gm of Hydrator-3.3 plus 80gm of Fatliquor-5.0 to replenish a 100gm dry leather from less than 1% back to the original tannery up from 14% to 16% fatliquor content.
In every bottle of Fatliquor-5.0 by weight content is comprises of 16.66% ionic negative (-ve) charged fat and oil, and 83.33% of water, the water content that encased the fat and oil molecule in an emulsion suspension when hydrogen bond with the ionic positive (+ve) leather protein fiber will break free and discharged clear from the leather structure to the surface.

Instruction:
1 Warm-up and shake well to a full emulsion for better penetration.
2 Apply Fatliquor-5.0 and redistribute with foam brush until saturation.
3 Repeat applications each time water contents evaporate until fully saturated.
4 Drive remaining surface remnants free of milky fat and oil until it turns clear with Hydrator-3.3.
5 Allow natural drying for extra softness.
6 Suppleness for vegetable-tanned leathers is further stake or massage or flex accordingly with a little wet back with Hydrator-3.3 prior to doing so to prevent cracking from under replenished leather.
Tips:
1 When crispy dry, prior surface contaminations/damages may darkens as soiling particulates resurface.
2 Removes soiling particulates with Eraser-4 for all leathers including nubuck and Eraser-5 for suede.
3 Stretching the darken areas lightly will also lightens the appearance.
