My brother spilled milk all over his Galaxy S2, I told him to just get a new phone because that phone is garbage, but he refuses. I know that you can repair corrosion, especially in phones because not much moisture can get into deep components. He just recently damaged it and has been soaking that shit in rice, but if I can open it before corrosion occurs, can I just dry it off internally? Or should we just leave it drying, let it corrode and remove the corrosion chemically?
