>>> How should we strip off dye?
Finishes stripping is done with Stripper-2.3
>>> And I think we will need Degrease-2.2,
Degreaser-2.2 has to go below the penetrated grease.
>>> rinse arms until oil is removed.
Structural or below surface rinsing is done with Hydrator-3.3 with “reverse transfer” technique.
Above surface is rinse and pH control the sweat contamination to a healthy squeaky feel with Acidifier-2.0.
When the amphoteric protein fiber is protonated and gain or increase in ionic positive (+ve) attraction, the ionic negative (-ve) fatliquor when replenished will replace and push out the stuffing foreign contamination without ionic charges simultaneously. This is assumed that the on-going Hydrator-3.3 dwelling is at its optimum level and allowing the displaced soiling particulates to “swim” or wick to the surface. Sufficient Degreaser-2.2 also plays a part in dislodging or deflocculating the foreign contamination, without Degreaser-2.2 the foreign oil and grease contamination still remain stuck within the protein fiber.
Note that most of the original fatliquor would have been replaced or leach out with contaminated body oil, grease and sweat and once removed may leave the leather empty and when crispy dry with poor handling cracks the leather. To prevent potential stiffness that leads to cracking. 20% of fatliquor is added to the Hydrator-3.3 during the “reverse transfer” process
>>> I think we will need Aniline-76 or Antique-27 from you. 500ml
Prior to either translucent coating dyestuff with Antique-27 or transparent coating dyestuff with Aniline-76, preparation work with Adhesor-73 plays an important role in proper adhesion. Adhesor-73 also plays a multi-role function and the final contribution to the color appearance and a choice of transparent or translucent will be decided after Adhesor-73 final dry inspection.
Urethane topcoat AnilineTop-76 gloss is first used to improved strength to the finishes and satin luster is for final luster adjustment. Protector-B+ applies to reduce friction rubs from delaminating or peeling.
Leather Problem Solving Guide used for reference is Aniline (A) for urethane standard gloss / satin topcoat.

Leather Doctor Kit-A7.cl is the recommended kit and Antique-27 may be used in conjunction with Aniline-76 for better blemishes coverage after final Adhesor-73 inspection.

Leather Doctor® Kit-A7.cl, aniline leather dye refinishing kit is designed for dyestuff and topcoat refinishing from the simple sunlight fading to the severely sweat damages from body oil and grease. Most severely penetrated, prolonged and neglected stains show a darkening effect with a sticky feel have its topcoat and dyestuff probably deteriorated by the sweat. When the stain feels sticky, it is a sign of leather denaturing and reverting to rawhide from breaking of bonds with the tanning agent. When sign of color is transfer to a white towel, it indicates that the dyestuff has also break bonds with the protein fiber. When leather is stiff or shows signs of whitish residue migrating, it shows that the fatliquor is breaking bonds as well with the protein fiber. The main component of the leather protein fiber is amphoteric while the other constituents are not; shifting of the pH mainly caused from sweat to alkalinity affects the pH imbalance. To revert from denaturing into rawhide prior to topcoat refinishing, contaminated alkaline soiling is removed with Degreaser-2.2, a waterbased (pH 2.2) multifunctional degreaser that emulsifies greasy contamination besides controlling 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 and pH balanced with Acidifier-2.0 to prevent the leather from reverting to rawhide. When leather feels sticky or slimy it is a sign of leather denaturing, a squeaky feel when wet is a sign of a healthy leather. Hydrator-3.3 relaxes stiff leathers and removes surface tension free from surface blotchiness prior to fat and oil replenishing. Fat and oil is replenished with Fatliquor-5.0 to rejuvenate the leather for the desired suppleness when dry. Custom redyeing commences prior to topcoat refinishing. Protector-B+ imparts a non-stick rub-resistant protection with a buttery-feel that shield against sticky soiling and reduce friction noises. Note that the mentioned product suffix number denotes its pH value in this holistic leather-safe aniline leathers dyestuff and topcoat refinishing system. Please email
