Steve65E-NC Posted August 23, 2020 Report Posted August 23, 2020 I have some internal wing root blue fuel stains from a, now replaced, fuel level sender gasket. What best removes that stain with minimum impact on chromate paint and internal tank sealer. I tried vinegar and avgas but they did not appear to touch it.
EricJ Posted August 23, 2020 Report Posted August 23, 2020 Mineral spirits, acetone, MEK, in ascending order of aggression. Acetone usually takes it right off in my experience. Just don't go crazy with it and your paint will be fine. All of them evaporate fairly quickly. 1
ArtVandelay Posted August 23, 2020 Report Posted August 23, 2020 I would try avgas/mogas first, and maybe nail polish remover before pure acetone...should be less harsh.
xavierde Posted August 23, 2020 Report Posted August 23, 2020 Kerosene is supposed to work well and was recommended in some Mooney POH to clean oil on the aircraft belly. 1

Nail polish remover is typically acetone, sometimes MEK. It's just a lot more expensive and in a prettier package. 1

You can’t even find MEK anymore, they have a MEK substitute now, and nail polish remover has also been changing...now they use less harsh chemicals.Tom
N201MKTurbo Posted August 24, 2020 Report Posted August 24, 2020 Ethanol (AKA denatured alcohol) works as well as MEK. Might take the paint too. Try a little bit first. 1
