Well basically I've sweated pretty badly in my Toms, so it's made them have awful sweat stains on the insole. I heard that salt got rid of them on the internet, so me being silly I decided to heed this advice. To my dismay, the next morning I found my Toms to have even worse sweat stains, which have turned almost black. So is there a way to wash black Toms which will get rid of the sweat salt stains? I really don't want the colour to fade too, so is there any way to stop that?
