i bought a camel colored kooba in december and it got caught in a bad downpour of rain a few weeks ago. there are now some streaky watermarks on it. although they "sort of" blend into the distressed look of the leather, they are driving me crazy and i haven't worn the bag since (although that could be due to the 3 others i have ppurchased since ). any advice on the best way to clean up or soften the look of these watermarks? for future rainfall, what's the best way to prevent this (besides not wearing the back ie. product recommendations for treating)?
