The below recommended product system for the steering wheel would also apply to the seat; instead of using the Degreaser-2.2 > Rinse-3.0 system, the seat restorative cleaning system would be Prep-7.7 > Cleaner-3.8 > Rinse-3.0. All the rest are applicable in similar fashion.

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.
Restorative Cleaning System
This is the ultimate restorative or salvage cleaning system that removes accumulated soiling including the unwanted aged old conditioners to its original OEM finishes. Accumulated soiling that fills creases is often mistaken for cracks. This restorative cleaning is also achieved by the strength of the Prep-7.7 to effectively deflocculates those tough soiling with the help of the detailing horsehair Brush-1.
Instructions
1. It is recommended to use tap water for a wet finger test for tackiness or sliminess. If it is, acidifying it with Acidifier-2.0 found in Kit AP3.T to return the leather to a squeaky feel is highly recommended prior to Prep-7.7 application.
2. Apply Prep-7.7 and agitate with horsehair Brush-1, to a panel at a time and let dwell for ˝ to 1 hour to deflocculate tough soiling.
3. Towel extract the suspended stain and check if the leather color is removed at the same time, especially where the topcoat has already worn out prior to application; protective matching satin or matte luster Topcoat-72 is recommended to further protect the colorcoat after Rinse-3.0, even though color may remain intact. Stain removal needs to be continued; otherwise it will eventually wick up on the new finishes too.
4. Sticky residue is removed by Cleaner-3.8 with gentle brush agitation and extract until towel shows clean.
5. This restorative cleaning system ends with Rinse-3.0 spray and towel extract to a squeaky 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.
