Phase 1: Degreasing with pH Neutralizing.
This damage is mainly cause by the working of sweat that shifts alkaline when fermented by the natural bacteria from the atmosphere. Decontamination would involve the use of a low pH degreaser that both neutralize the alkalinity and degrease body oils at the same time.
Phase 2: Wet Prep.
This phase is to remove the deteriorated finishes during the rinsing step – where the leather regains strength while the finishes weaken for effective physical removal.
Phase 3: Leather Softening and Strengthening.
The entire leather is hydrated to relax and soften up the leather. As the leather plumps up, you may observe the closing of the gap. This hydrating step plays a few function: to further wick up suspended soiling particulates to be extracted while damp and erased when crispy dry; to relax and separate the stick together fiber and reduces the interfacial surface tension for effective fatliquoring; to further charged the protein fibers below its iso-electric point positive for effective hydrogen-bonding with the negative charged fatliquor. Fatliquoring follows to replenish the leather at drying interval as water evaporates until fully saturated.
Phase 4: Bonding Repairs.
This repair is done with water-based leather bond in combination with leather fibers (scrape from a donor leather piece) for filling up. This homogenous repair ensures no further cracks for at least the next 5 years.
Phase 5: Dry Prep.
This phase is to smooth the leather surface ready for refinishing.
Phase 6: Refinishing.
The leather refinishing involved an adhesion coating to ensure good anchorage into the leather pores to prevent peeling. Follows with the desire custom color and protected with a urethane topcoat.

Leather Doctor® Leather Degreaser Kit AP3.dr
Auto pigmented leather degreaser Kit AP3.dr - features Degreaser-2.2 with a pH value of 2.2. This is a high viscosity aqueous formulated leather degreaser; for degreasing leather of penetrated sweat, oil and grease stains from skin and hair contact. In most cases the finishes in these areas has deteriorated to allow such penetrated grease into the leather structure. Degreasing the leather structure will inevitably remove these deteriorated finishes as well. Therefore finishes restoration is a mandatory recommendation with degreasing as the 1st phase. Follows with leather rejuvenating as 2nd phase; leather impregnating as the 3rd phase; adhesion coating as the 4th phase; color coating as the 5th phase; top coating as the 6th phase and ends with a non-stick rub resistant protection for a holistic approach to leather restoration.

Degreasing System Instructions
1] Shake very well until it turns to an opaque gel.
2] Apply direct and agitate with horsehair Brush-1 to penetrate into the stain.
3] Let dwell 5 to 30 minutes or before it dries for chemical reaction to occur, follows with towel extraction.
4] Suspended residue is to be rinse with Rinse-3.0 and towel extract until towel shows clean.
Leather Rejuvenating System
Rejuvenating system is the process of restoring the original fatliquor diminished through aging and cleaning to return to its characteristic suppleness. Leathers, when wet and then dry again, have the tendency for the fibrils to becomes stick together - known as the Van der Waals or London force phenomenon. This results in stiffness and when flexed, may lead to premature cracks, as often seen on neglected leathers. It is recommended to hydrate these exposed leather structure and replenish the diminished fatliquor while it is still damp. When dry thereafter, the leather fibrils will be well separated and lubricated to slide over one another smoothly during practical usage.
Instructions
1] Apply Hydrator-3.3 with the foam brush to the exposed absorbent areas, especially the stitching seams and perforated panels.
2] Semi-absorbent panel is best applied through a layer of paper towel acting as reservoir, to allow a slow seep through the micro cracks.
3] The entire seat is thereafter wrapped with clear plastic sheet, to control evaporation for an overnight dwell.
4] A visual and hand massage inspection are to ensure thorough hydrating, with structure softness without blotchiness.
5] Fatliquor-5.0 follows the same procedure as the Hydrator-3.3, with in between drying application as water evaporates.
6] When dry the surface is check for strays from milky to clear, using the hydrator to further drive the fatliquor into the leather structure.
7] The rejuvenated leather is left for slow natural drying for extra softness.
