Hi there. I have a light colour mulberry brook bag that I bought from eBay a wee while back. It did have a dark mark along the top and I tried to clean it but I think I made it worse. I had also applied collonil waterstop too. So, Can this be cleaned back to the original colour, or should I try to dye it a bit darker to match. I'm not bothered about it being a darker tan/brown in the end of the day. I've added a pic of an older mulberry wallet and wondered if anyone knows the colour. I think I heard it described at teak but I could be wrong. Thanks folks.
