Unless a Premium Leather option was purchased the type of leather upholstery used by ~ 95% of OEM is a multi stratum covering over the leather hide; the top strata is the surface pigmentation (colour) and an abrasion resistant urethane.
Premium leather has a recognizable fragrance that is missing from polyurethane and plastic. Simple cleaning, hydration and protection are the steps that will prolong the life of finished leather.
1. Clean - there are two cleaning-related factors that can cause your leather to wear prematurely. The first is dirt, and the second is oil, combined they become very abrasive, as dirt / grit and subsequent friction cause the finish to wear
2. Hydrated – when leather tanner’s talk about conditioning leather they are referring to its moisture content, re-hydration is used to restore or maintain fluid balance (transpiration and evaporation of moisture); not the replenishment or replacement of the fat liquoring, oils and / or waxes.
3. Protected - is essential as it will protect the surface finish as a sacrificial layer; this way you are not actually cleaning the Leather's original surface, but cleaning from the surface of the protection. It also makes dirt easier to clean off
Leather Master™ Leather Degreaser - an aerosol product for cleaning oily stains; it dissolves and removes oil and grease from leather surface. This cleaner can be applied for cleaning all types of leather (check for colour fastness) this aerosol product is ideal for cleaning this type of stain as it dissolves the oils and transforms them into a powder that is more absorbent than the leather.
This powder is what is wiped off, cleaning and degreasing the leather. Allow the white powder to dry fully. If the powder is drying to a yellow colour, it means that there are still a lot of oils in the leather.
