products than can prevent ringworm

I've gotten ringworm twice already. Anybody know of any products that I can put on before I train to prevent from getting ringworm again? I think I might have seen something on a wrestling website that wrestler's use. Is there anything I can get just from a store.

1. don't live in a 3rd world country
2. stay away from dirty ass places

not much else. if you're in a place that has a lot of em, you're bound to get em no matter what you do.

Wear long sleeve rashguards.

Dont roll with funky people.
