i just bought some lugz and i never really had suede leather boots before (im more of a sneaker or regular leather fan) and the first day i got them i scuffed them already..so theres a nasty black mark. the tag on the boots said to use a damp cloth and mild soap to clean, i tried that and it didnt work, so i bought some suede cleaner shit at the store, and that didnt work either. any ideas?
