1 – Degreaser-2.2 - purpose is to degrease penetrated soiling.
Application is to reach the depth of the dark appearing soiling, horizontal distribution maybe by foam brush or detailing brush however more important is to work with the horsehair Brush-1 into the depth of the soiling.
2 – Surface rinsing is performed with Acidifier-2.0, which also acts to pH balance the ‘sweat’ contamination with a dry cotton extraction.
3 – Deep rinsing will require Hydrator-3.3 to disperse emulsified soiling particulates to the surface and time plays an important factor for it to floats to the surface, and fully saturating it and evaporation control with plastic covering facilitates the soiling removal to the surface. The Towel-5 used to become an extension of the leather surface helps to wick the soiling through and when dry is easily to peel off.
4 – An option during the Hydrator-3.3 process is to removed the partially damaged topcoat with Razor-60

and refinish with a new topcoat to seal off the damaged cracking existing topcoat.

5 - The stain removal process may be repeat until satisfactory prior to Hydrator-3.3 > Fatliquor-5.0 > Hydrator-3.3 system. The 1st part of the Hydrator-3.3 in this system is to precondition the leather to easily accept the Fatliquor-5.0. The 3rd part of the Hydrator-3.3 is for rinsing off any Fatliquor-5.0 residue from the leather surface. The previous Hydrator-3.3 under plastic wrapping is to move penetrated soiling particulates to the leather surface.
Here is an example of Topcoat Refinishing.
