Okay, so my fog light of the passenger went out last night and I pulled the bumper off today to check out what the issue could be. Well I open up the fuse relay on my fog light HID kit and look what I found...
Ive already checked every other connection for my headlights/foglights and these are the only two with corrosion. Its definitely water, one of the fuses was still wet (rained like hell yesterday) and it had to be cause the two relays werent tucked away well enough

.
I can get these tucked away so this doesnt happen again but does anyone know of a good way to clean these connections, should I run to the store and get some CLR or something like that...? Any help would be much appreciated!
TIA
