A new black leather interior by Katzkin with blue embroidery – What level of care would you recommends?

Black Pigmented Leathers:
Although pigmented leathers for auto is usually non-absorbent, there are weak points where original fatliquor evaporates as gases and foreign liquid contamination being absorbed that affects the balance of the chemistry integrity of the leather. Leather is an amphoteric material especially the protein fibers where alkalinity such as the fermenting of sweat will weakens the protein ionic attraction between the other leather constituents especially the original fatliquor (fat, oil and water). Such weak areas mentioned have to be pH balance especially from sweat with routine maintenance with Rinse-3.0 (pH 3.0). Thereafter, these weak areas has to be hydrated with Hydrator-3.3 (pH 3.3) follows with Fatliquor-5.0 (pH 5.0) to maintain its softness and stitch strength. The stitch strength weakens below 2000psi will subject to split when stress.

Embroidery:
Embroidery with too close needle stitching holes that looks perfect have its down side as the continuous rows of stitching holes pose a potential of ripping when the leather structure loose its rip tensile strength. The synthetic thread is clean with similar products use for leather as well – so one products takes care of both fabric that preserves its color as well as its strength with the leather-safe range of pH between 3 – 5, the isoelectric point of leather or pI.

Stitching Rows:
Cleaning is same as for the embroidery – Hydrator-3.3 > Fatliquor-5.0 follows after for continuous softening and strengthening the leather from stitch rip. Note: a strong leather will have a almost round perfect needle holes, as the strength weakens these stitching holes becomes elongated and will eventually split and when connected will easily rip the leather.

Seams:
Have a close look at the seams, observe the needle holes mentioned are they round or slanted or already split. Remember that new leather is from the tannery. A new product may be made from leathers that is already dried of its fatliquor and may be a few years old already.

Regiment or Maintenance Program.
Refer to the Pigmented Leather Problem Solving Guide for its level of care – Preventive, Routine, Periodic, and Restorative etc.

Sweat:
Sweat has its traces of urea and it is this urea that attracts the natural bacteria from the atmosphere that when ferment shift the leather protein fiber ionic negative (-ve) that denatures the leather. And with neglect we often see the result as staining and cracking.

Recommended Care Kit – Kit Ap3

Attachment 1730

Leather Doctor® Kit Ap3, auto pigmented (perforated) leather care kit is an innovative leather-safe (pH 3 - 5) system designed for keeping leather interior at their highest level of appearance while maintaining their structural chemistry integrity and enhancing their suppleness with needle holes tear strength. Auto leathers are often under hot sun and those exposed to thermal heating during cold season dries out their fat and oil sooner. The first place to check for leather dryness is the stitching holes, if they are perfectly round the leather is healthy, dried out leathers will show signs of elongation or splits. The diminishing of the fat and oil will results in stiffness to the leather and when flexed or stretched during used will lead to cracks or rips first to the stitching holes. Periodic use of Hydrator-3.3 to hydrate the stick together fibers in these weak points prior to fat and oil replenishing with Fatliquor-5.0 will keep the leather supple with increase tensile strength. Thus, reduce the premature ageing of the leather against stiffness, tearing and cracking. Protector-B+ impart a non-stick rub resistant protection with a buttery feel that makes sliding in and out of seat smoothly. The rub-resistant abilities reduce friction noises that translate into less friction wear especially to the side bolster. Periodic cleaning and rinsing with Cleaner-3.8 and Rinse-3.0 respectively to the steering wheel leather helps reduce greasy sticky soiling build-up. Removing of unwanted stains such as the common new blue jeans is accomplished with Prep-7.7. Note that the mentioned product suffix number denotes its pH value in this leather-safe holistic care system.

Instruction:

Preventive Care:
A non-stick, rub-resistant protection is recommended to be in place before putting the leather to daily use. Protector-B+ imparts a soft natural buttery-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 reduces friction noises that translate into less friction wear as one slide in and out of auto seats effortlessly with less stress to the seat bolsters. This leather-scented protector diffuses a classic leather scent that boost the sensuous leather more appealing to the leather lover. This protection care commence at the end of each level of routine, periodic or restorative cleaning cycle. A simply spray and wipe prolongs the need for cleaning heavy soiling.
1. Apply Protector-B+ to the seats and Protector-D+ to steering wheel including the gear shift knob after shaking well spread with lint free towel 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 swear stains from shifting alkaline. Thus prevents leather from tackiness. A routine non-stick rub resistant protection after neutralizing rinse helps keep leather interior in a more attractive and healthy state while preventing premature wear.
1. Spray Rinse-3.0, horsehair Brush-1 agitates and towel extract until it shows clean.
2. Apply Protector-B+ to the seats and Protector-D+ to steering wheel including the gear shift knob after shaking well spread with lint free towel 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. Driver’s seat would require more frequent attention than the other less frequent used seats. While the leather steering wheel and the gear shift knob get the most of body oil and sweat contacts.

1st phase – Periodic Care:
1. Spray Cleaner-3.8 and agitate with horsehair Brush-1; ensuring a uniform 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:
Although pigmented leathers surfaces are usually non-absorbent until micro crazing develops, it is the stitching rows and perforated holes that are usually vulnerable. These weak areas when wet and dry again have the tendency for the fibrils to become stick together resulting in stiffness and when stressed may lead to premature cracks. Hydrating is essential to relax and separate the stick together collapsing fibrous structure. Besides, charging the protein fiber ionic positive for a more effective hydrogen bonding with the ionic negative fatliquor.
1. Spray Hydrator-3.3 control and spread with foam brush to hydrate especially the stitching rows and perforated sections.
2. Let dwell 10 to 30 minutes depending on severity of dryness with optional plastic cling wrapping to control evaporation for a longer dwell time to plumps the leather more effectively.

3rd phase – Fat and Oil Replenishing:
Fatliquor evaporates as VOC (volatile organic compound) when temperatures rises especially from exposed micro-crazing, perforation and stitching rows. Periodic fat and oil replenishing maintains the leather’s structure integrity and pliability thus strengthen these exposed leather from cracking.
1. Spray Fatliquor-5.0 in like manner as Hydrator-3.3 and let dry naturally.
2. Repeat application in between drying until saturated.
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. Apply Protector-B+ to the seats and Protector-D+/D to steering wheel including the gear shift knob after shaking well spread with lint free towel 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 using Prep-7.7. 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-7.7 can stay continuous for up to 72 hours to do its work safely.

1st phase - Restorative Cleaning:
1. Apply Prep-7.7 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 Cleaner-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-7.7 application with a longer dwell time as necessary or proceed to hydrating.

2nd phase – Hydrating:
Although pigmented leathers surfaces are usually non-absorbent until micro crazing develops it is the stitching rows and perforated holes that are usually vulnerable. These weak areas when wet and dry again have the tendency for the fibrils to become stick together resulting in stiffness and when stressed may lead to premature cracks. Hydrating is essential to relax and separate the stick together collapsing fibrous structure besides charging it ionic positive for a more effective hydrogen bonding with the negative ionic fatliquor.
1. Spray Hydrator-3.3 control and spread with foam brush to hydrate especially the stitching rows and perforated sections.
2. Let dwell 10 to 30 minutes depending on severity of dryness with optional plastic cling wrapping to control evaporation for a longer dwell time to plumps the leather more effectively.

3rd phase – Fat and Oil Replenishing:
Fatliquor evaporates as VOC (volatile organic compound) when temperatures rises especially from exposed micro-crazing, perforation and stitching rows. Periodic fat and oil replenishing maintains the leather’s structure integrity and pliability thus strengthen these exposed leather from cracking.
1. Spray Fatliquor-5.0 control and spread with foam brush to hydrate especially the stitching rows and perforated sections.
2. Repeat application in between drying until saturated.
3. The leather is left for slow natural drying for extra softness.
4. Surface strays are wipe with Hydrator-3.3 to free of sticky residue.

4th phase – Preventive Care:
1. Apply Protector-B+ to the seats and Protector-D+ to steering wheel including the gear shift knob after shaking well spread with lint free towel and is ready for use when dry.
