Radiator cleaning

not the inside but the outside.It has some of the green corrosion on it.I want to paint it before installing it and wondered if anyone had a way to get it good and clean.

You might try some vinegar and a toothbrush on it. Just put some in a spray bottle, spray it on and let it set for a few minutes. I don't know about that type of corrosion but it works on computer motherboards that have corrosion on them.... If you try it let us know either way. (works or not)

Re: Radiator cleaning

In the olden days we would pour cola on battery terminals to clean corrosion, it may work for your application. I need to do the same thing to my rad.

Re: Radiator cleaning

tobasco sauce and a wire brush works to take corrosion off of brass valves should work for that.

Re: Radiator cleaning

Don't know about the rest of you but everytime I had green corrosion it indicated a leak. Might be so small it evaporates so you never see the leak but it will get worse. Take it to a radiator shop and have them check it out. Might save problems later on.
