Pictures #3 & #4 shows Hand Grease Embedded Stains!
Phase 1: Degreasing.
Procedure for degreasing and restoration cleaning prior to color refinishing is as follows:
Use Degreaser-2.2 to penetrate, lubricate and suspense the embedded greasy soiling with the help of Suede-Brush-3.
The process continues with acidifier Rinse-3.0 thereafter to extract the suspended grease until towel shows clean.
Fast dry it to a crispy-dry then use Nubuck Eraser-5 to erase wick-up soiling particulates and exfoliating for new nap simultaneously.
Inspect for degreasing satisfaction, otherwise repeat where necessary.
Note: Need to warm-up the Degreaser-2.2 and shake until it turns to a milky gel prior to use.
Prep clean the non-greased areas with Prep-4.4 > Cleaner-3.8 > Rinse-3.0
Leather Doctor® Degreaser-2.2:
It's for all Pigmented, Aniline, Nubuck and Suede leather types.
This is a pH 2.2 high viscosity aqueous formulated leather degreaser.
It’s primarily for degreasing leather of penetrated oil and grease stains from skin and hair contact prior to refinishing.
Also assist in removing solvent based stains like permanent marker, paint and nail-polish.
Oil and grease based stains like: crayon, wax, ballpoint ink and lipstick.
Dye-transfer stains from blue jeans, ink prints and newsprints.
Leather Doctor® Prep-4.4:
It's for Aniline, Nubuck, Suede and all Absorbent leather types.
This is a leather-safe pH 4.4 aqueous high viscosity leather preparatory cleaner.
It works by allowing sufficient dwell-time to penetrate, lubricate and suspense foreign soil contamination prior to Cleaner-3.8.
Leather Doctor® Cleaner-3.8:
It's for all Pigmented, Aniline, Nubuck and Suede leather types.
This is a pH 3.8 all purpose leather-safe anionic cleaner that is particularly effective in emulsifying oily soils and in suspending particulates.
It cleans by penetrating, lubricating and suspending soiling safely and effectively through gentle chemical reaction.
Cos its pH value works in perfect harmony with all leather constituents that include the tanning agent, preservative, fatliquor, dyestuff and others.
Leather Doctor® Rinse-3.0:
It's for all Pigmented, Aniline, Nubuck and Suede leather types.
This is a pH 3.0 aqueous leather-safe rinse to neutralize harmful alkaline and perspiration residues.
It’s for stabilizing and strengthening leather constituent pH chemistry integrity.
And cationizing (+ve) protein fiber below its isoelectric point to increase hydrogen bonding prior to anionic (-ve) Fatliquor-5.0
Phase 2: Leather Rejuvenating.
Hydrate with Hydrator-3.3 evenly follows with Fatliquor-5.0 adequately and rinse the fatliquor for stronger hydrogen-bonding with Rinse-3.0 of any strays fatliquor.
Leave it for very slow drying (cover up to reduce evaporation overnight to freshen up the dye shade difference those faded areas as revealed in picture #2).
Leather Doctor® Hydrator-3.3:
It’s for Pigmented, Aniline, Nubuck, Suede, Hair-on and Woolskin leather types.
This is a pH 3.3 aqueous leather-safe hydrator.
It’s for hydrating dried, stiffed or shrunk leathers (to separates the crushed, stick together fibrils and relax them) prior to strengthening and softening with Fatliquor-5.0.
And it’s also used for facilitating colloidal water movement within the leather structure capillary motion during the wicking process.
That will cause suspended soil particulates to be moved to the leather surface to be extracted with rag while damp and erase with Leather Eraser-4 when dry.
Leather Doctor® Fatliquor-5.0:
It’s for Pigmented, Aniline, Nubuck, Suede, Hair-on and Woolskin leather types.
This is a pH 5.0 anionic charged micro emulsion fatliquor leather rejuvenator.
It’s for replenishing original fatliquor that diminishes thru sun-bleaching, ageing, heat and alkaline exposure or cleaning.
It penetrates and lubricates the leather fibers so that after drying they will be capable of sliding over one another smoothly.
Besides softening the leather with stretchability, compressibility and flexibility, it enhances the leather rip resistance tensile strength greatly.
Thus relaxes coarse breaks, creases and wrinkles to provide drapes, suppleness and prevents cracking.
It helps to keep leather at its optimum physical performance and prevent premature ageing.
Phase 3: Color Refinishing.
Use color matching - Leather Doctor® Nubuck Color-94:
It's for Nubuck and Suede.
This is an aqueous non-bleed micro-pigment color formulation.
It’s to provide an excellent hiding power with opacity.
Phase 4: Color Fixing.
Use Leather Doctor® Nubuck Fix-99: for Pure-Aniline, Nubuck and Suede.
This is an aqueous formulation color fix spray to abate crocking.
Crocking is greatly reduced or eliminated on most leather with good fixing of both dyes and micro pigment colors.
It improves wet rub fastness and reduces bleeding.
It maintains the natural feel and “finger writing effect” of the nap.
Phase 5: Non-Stick Protection.
Use Leather Doctor® Leather Scent-S:
It’s for Pure-Aniline, Nubuck, Suede, Hair-On and Woolskin leather types.
This is a non-film forming, non-stick protector that enhances a natural silky-feel with a classic leather scent that charms.
It imparts a non-stick surface essentially to shield the detrimental effects of sticky soiling including the nasty ballpoint ink.
And it does help to release those tenacious dye-transfer stains especially on light colored leathers easily without resorting to unnecessary color refinishing.
Its natural silky-feel protection increases the leather resistance to wet and dry rubs, thus reduce stretch, scuff and abrasion.
And it reduces friction squeaks that wear the finishes when leather rubs against leather during movement.
