This chair is identified as Aniline leather with a gloss finish.

A complete restoration of degreasing, replenishing fat and oil, dye and topcoat refinishing is complete with Kit A7.cl.

Stains are penetrated and degreasing is likely to remove some of the deteriorated topcoat that will require a refinish.

The dyestuff may have break bonds with the protein fiber and a test with a white terry towel may confirm the fugitive dyestuff and may require a dye refinish as well.

The structure of refinishing takes this sequence of processes:

1.] Strip Existing Topcoat
Stripper-2.3

2.] Degreasing:
Degreaser-2.2 > Acidifier-2.0

3.] Fat and Oil Replenishing:
Hydrator-3.3 > Fatliquor-5.0

4.] Adhesion Coating
Adhesor-73

5.] Surface Dye Coating
Aniline-76

6.] Topcoating
AnilineTop-21G

7.] Non-Stick, Rub-Resistant Protection
Protector-B+

Leather DoctorŽ Kit A7.cl is designed for dyestuff and topcoat refinishing after degreasing in a holistic approach. Most severely penetrated, prolonged and neglected stains from the bare head and hands that show a darkening effect with a sticky feel have its topcoat and dyestuff probably deteriorated by the oil, grease and 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 show 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.
