Does anyone here have any experience rehabbing a bone/cream/ivory colored vintage bag? I recently got a bone (or cream or ivory, I'm not sure which the official color would be) convertible clutch that is in good condition, but somewhat dirty. I gave it a bath and some coats of Cadillac and Apple, but it's still a bit on the dingy side. I can tell because the hang tag and the panels beneath the front flap are still a few shades lighter than the flap and strap. I know borax has been suggested here before, so I'm wondering if anyone has any suggestions or tips on de-dingyfying (my new word) a lighter colored leather.
Also, while overall the bag is in good condition, the edges have a kind of yellowish tinge which I'm not sure if it is grime or just rub wear. I'd be much obliged for any suggestions!
