Corrosion-X 90101 6oz Aerosol

I use this on my rc boats, works well but pricey.

Good stuff. I've used this before - great for cleaning corroded electrical terminals.

Not only did I pay for the smaller can because I wanted the flexy nozzle but they sent me the larger can. No flexy nozzle but I'm grateful for the extra 10oz's that comes in the big can. Great product, I like that it is safe for use on electronics which is what I bought for. It does stink so make sure you use outside or in a well ventilated area.

Corrosion X is awesome, lasts and doesn’t get gummy like another popular brand.

So far I really like this stuff; I have been using it to help in the refurbishing of 50 year old audio equipment. I use it as both corrosion elimination and protectant. It is also a pretty good cleaner; This equipment often has filmy buildups and accumulated residue like nicotine as well as mouse pee. This seems to work as a single step to remove layers of grime while leaving a protective film behind. It works surprisingly well on the painted metal cabinet surfaces to remove oxidized paint and restore what little luster might be left after half a century. I have not yet found a surface material it is unsafe on. It also smells decent and the pressurized can propellant won't choke you out like some other products. The only downside I can think of is that it is a little messy to use.
