looking up solutions, I read a normal pink pencil eraser would work, since I don't have the block meant for suede and this is the shoe brush I had which I assumed would help. so it can be fixed by washing? all I've done it put water on the spot to try and make the darkness fade with it, but it just made it darker so I was hesitant to wash it. I read that if you rub it while wet or dry with heat it can be irreparable so I'm wondering if the spots are where I rubbed off the material. clearly I'm out of the loop though, lol
