That’s always a challenge. Oxalic acid is the best thing you can get for that. It’s a powder that you mix with water, that works great for cleaning. You can get it on our website for just $3.
Hi Kevin, I love your YouTube videos and really benefit from them. My question is: I make a lot of things that are natural veggie tan finish (I.e. not dyed). Working with the leather as hard as I try I can’t keep it clean. How do I clean it before I put my final finish on it (usually carnauba cream and resolene)?
