I’m a rehab newbie and just want to make sure I do this correctly. This mahogany color had what might have been an old oily and dried stain across the front flap that I spent a lot of time scrubbing out with leather cleaner before and during soaking. I’d say 90% of it is gone, but it’s also removed the color. What kind of dye should I use to fix this and should I avoid conditioning this area while it’s drying until I can dye or go ahead and condition? Appreciate any help
