Audi – Leather Water Damage!

A few issue:

Stiffness:
Leather stiffness below surface need rejuvenation with Hydrator-3.3 > Fatliquor-5.0 system.
Hydrator-3.3 has to go or penetrate where the water have cause shrinkage or causing the leather fibrils to becoming stick together – just like a rusted hinge that need to loosen up prior to lubricating with Fatliquor-5.0.
Stretching or massaging of the leather back to original dimension is also done with Hydrator-3.3 and may dwell up to 72hrs with evaporation control using a cling wrapper. When suppleness and dimensional distortion is first corrected or rectified Fatliquor-5.0 follows to soften up the leather when dry with strength.

Browning stains:
May be corrected by Acidifier-2.0 from high pH browning. Leather pH ranges from 3 to 5. High pH browns leather and low pH lightens up.

Color Appearance:
Otherwise a matching color restoration may resort appearance with this holistic Kit-Ap7.cl from this link:

Leather Doctor® Kit-Ap7.cl, auto pigmented (perforated) leather color refinishing kit is design for abrasion damages especially from friction rubs while getting in and out of seat. Most of these repairs may range from missing finishes to abrading damages into the leather structure. Some expose areas may be contaminated with foreign soiling that includes conditioners, protectors, body oil, grease and sweat or alkaline overexposure with all-purpose cleaners. A comprehensive repair for a long-term lasting solution will require a holistic approach to deal with both the exposed structure and surface finishes. The practical and functional softness and strength of the leather depends on the health of the structure with average thickness between 0.9 to 1.2mm from stiffness and cracking. The aesthetic aspect of the leather finishes averages 0.02mm (or 20 micron) in thickness for practical compressing and flexing from cracking. A preview of a leather-safe restoration system begins by stripping with Stripper-2.3 and rinsing with Rinse-3.0. Degreasing with Degreaser-2.2 follows with Acidifier-2.0. The suffix numbers of these four products denotes it pH value for recharging the protein fiber ionic positive besides the act of decontamination. The leather integrity is revitalized once the ionic attraction between the positive protein fiber and its negative leather constituents like the tanning agent and fatliquor (fat, oil and water) is activated. Leather rejuvenating system for softness and strength is accomplished with Hydrator-3.3 follows with Fatliquor-5.0. Structural weakness from overstretching is re-strengthened with Impregnator-26, while surface uneven absorption is sealed with Adhesor-73. These repair and auxiliary products where necessary reduces the need for color over-coating thus increase its flexibility and stretchability from premature cracking. Protector-B+ imparts a non-stick rub-resistant surface with a buttery feel, reduces noises that translate into less friction wear. As the leather surface is well lubricated it reduces compression when comes to heavy body contact thus reduces compressed creases and wrinkles.
