What happens if i clean a ringworm infection with lemon?

Uncertain.: Some say the lemon juice can be poured over a ringworm infection to treat it. I do not know if it is effective or not. It will likely tingle. One home remedy for treating ringworm is to rub the affected area of skin with a slice of lime dipped in salt (over the pulpy portion). Rub in & follow by rinsing. I can not speak to effectiveness of this approach.
