Will sandpaper and bleach cure ringworm?
Ringworm is a fungus therefore you need a fungicide to get rid of it. I guess you were joking about the sandpaper and bleach….that would make things far far worse and you would end up in hospital. Basically you need to kill the fungus without hurting yourself. The best, quickest, easiest way is with a fungicide cream. I would not recommend other ways.
