I have a pair of sneakers which are white and one time I put them in a black garbage bag with my other shoes .
After a couple of days I saw orange colored spots and dots on one of my sneakers midsole part .
I tried to clean them with anything that you can imagine but it just doesn't turn white .
Here is a picture of the damage been done to my sneakers :
How can I clean them ? If not can I do something else like changing it's midsole completely or cover it up with something white ?
