>>> Dog chews chicken bones on cushions.
Picture shows the darkening effect from the grease with penetrated stains that need to be removed with:
Degreaser-2.2 > Acidifier-2.0 > Hydrator-3.3 system.

And in most cases the topcoat will need to be restored.
>>> Worn area.
Worn areas are topcoat damages.
Restored with AnilineTop-76.
Prior to topcoat restoration the leather is recommended to be rejuvenated by Hydrator-3.3 > Fatliquor-5.0.
Leather structure rejuvenating with Hydrator-3.3 will activate excess or dormant dyestuff to resurface and fatliquoring with Fatliquor-5.0 will intensify or magnify the color intensity prior to topcoating. Fresh color is an option with color matching transparent coating Aniline-76 system.

>>> Scratches
Scratches will depends how deep it has penetrated.
Surface scratches are rectifiable with AnilneTop-76G with in between fine sanding.
Leather grain scratches my require Adhesor-73 or Bond-3D repairs, however for light to medium coloring an undesirable darkening effect may manifest. Solution to this darkening problem may just use AnilneTop-76G.
>>> UV faded
Overnight dwelling up to 72hrs with Hydrator-3.3 will bring excess or dormant dyestuff to the surface to a degree.
This process may save on the use of new dyestuff. Fatliquor contribute to the color saturation and diminished fatliquor when replenished with Fatliquor-5.0 will improve the color differences from other areas.
>>> Water rings.
When pure water that causes browning it is a pH value phenomenon and pH balancing with Acidifier-2.0 reduces or correct the browning.
Any liquid that contants any substances derived from plants and vegetation will need d’Tannin-3.5 to redox or deduction-oxidation treatment to reduce or eliminate the browning.
Protein stains has the tendency to coagulate and may need d’Protein-10 with bamboo skewers to work out the stains follow with immediate pH balance with Acidifier-2.0.
Bloodstains after d’Protein-10 the remaining rust stain will need to be removed with d’Tarnish-1.8.
Refer the steps from the guide for the various stain removal steps.

Leather Doctor® Kit A6.tc, aniline leather topcoat refinishing kit is designed for topcoat repairs from friction wear, accidental scratch, scuff and abrasion to deteriorating greasy sweat stains. These topcoat damages are identified as white, dull or darkening stain from bare body contacts. Accidental whitish damages in most cases are free of soiling and direct AnilineTop-21G application with in between dry sanding rectifies most damages. Repairs to topcoat from daily wears that dulls will require a degreasing to remove penetrated rub-in soiling prior to topcoat application in a sequence process including Degreaser-2.2 follows with Rinse-3.0; Hydrator-3.3 follows with Fatliquor-5.0 prior to topcoat application. In a greasy and sweaty topcoat damaged areas especially to the headrest and armrest, a deep degreasing is essential follows with Acidifier-2.0 to stabilize the hydrogen bonding between the protein fibers with the other leather constituent like the tanning agent, dyestuff and fatliquor. This deep degreasing process is assisted by leather Eraser-4 in both the wet and dry cleaning process to remove soiling particulates off the leather surface. Hydrator-3.3 helps in the colloidal water movement bringing suspended soiling particulates to resurface through a dwelling and wicking process. Fat and oil is replenished by Fatliquor-5.0 in an emulsion form to penetrate into the leather structure. Once the fat and oil is hydrogen bond with the protein fiber, the water content breaks free leaving a breathing space for natural transpiration. The fat plumps the leather with fullness preventing the leather structure from collapsing during compressing and flexing while the oil lubricates the fiber from sliding smoothly over one another like millions of connecting hinges. Protector-B+ impart a non-stick, rub-resistant surface with a buttery feel helps reduce friction wear to the topcoat and extended a high level of appearance for a longer period of time. When the leather is contaminated with foreign soiling, it is essential to look at topcoat refinishing in a holistic approach. Note that the cleaning and rejuvenating products suffix denotes its pH value in this leather-safe aniline leathers topcoat refinishing system.

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.
