Do Your Research
I bought this because I'm trying to bleach black leather boots. I give this product 4 stars because I'm not sure if this is a user error or not. It arrived well packaged, clean, easy to use and keep safe. I did extensive research on how to bleach leather and followed the directions meticulously. I prepared my leather, trying multiple methods and prepared the bleach solution.  This package doesn't come with instructions, so I had to go off of the reading I'd done. I mixed 30ml (2 tbsp) dry with 2 cups of room temperature water. I placed my leather in this solution for 10 minutes, allowed 10 minutes to dry. This did nothing. So I gradually turned up the amount of time I let the leather soak and dry. At the longest, it was left soaking for 3 hours and dried for over 24. No difference.<br />All I can think is that I either didn't properly deglaze (although I spent a great deal of time on that), I need to increase my oxalic acid to water ratio so the solution is more potent, or I need to somehow strip the dye from the leather instead of bleaching.<br />I plan on spending more time deglazing my surface and increasing my solution.<br />I'll try to remember to report back once I have, but right now, this product has failed me epically.
