How to get rid of stains from veg tanned leather?
How to get rid of stains and mold(if they are mold) on my veg tanned leather bag? Bag is undyed, original color is light flesh color.
Products I have used: Columbus Get Cleaner (Japanese), Lorence Bio-based leather cleaner gel (Chinese) both failed to get rid of stains.
For mold, tried leather furniture mold remover, did not work. Bought Columbus Platinum Leather Care because the sales at leather shop recommended it but found out can't use it for veg tanned leather so annoying as I brought my bag for her to inspect! Used Fiebing's Golden Mink Oil and it darken the leather by 4 or 5 shades, but does nothing for the stains.
