The surface accumulated soiling is first removed with either Prep-7.7 for non-absorbent leathers and Prep-4.4 for absorbent leathers. There after the remaining residue is removed with Clean-3.8 > Rinse-3.0 system
Part of the stain in most cases is also removed. Otherwise remaining dye related stains are removed with CleanDye-7.9 > Acidifier-2.0 to pH balance to the leather pH neutral.
Sun fading restoration will need a color refinishing.
Note:
Test out with some water to see if it pools on its surface or absorbed and darkens.
