Killing the Killer

[odin]

So I've got a little 024/024s project going on. One case is a bit busted up in one corner and the second one, while newer and mostly nicer has, what do you boys call it... the white death? That corrosion that looks like invisible rust? It's not too bad, but it's there and I'd rather deal with it now than have an unusable saw in a year or two.

So two questions: What causes it? And how can I stop it?

It's oxidation. I usually clean it up with a wire brush and Clean down in the divots with a pick. Then paint it. Either that or I sandblast it and JB weld it if it is really bad.

 

[P.M.P.]

Chit Wipe down keep it away from the concrete but I know nothing

Alodine,is a conversion coating that stops it.

Thanks gents, I was kinda hoping a little cleaning and coverage with a rattle can would put a stop to it, or at least slow it down a good bit.

Dang, that Alodine sure is spendy stuff.

I read somewhere you're not supposed to use a wire brush. Not sure. Some sort of chemical reaction. I'd clean it up best I could (probably with a wire brush), spray it off with carb cleaner, skim it over with jb weld, and paint it

The word I got is that a brass brush is ok. Pieces of steel from a regular wire brush supposedly get embedded in the Mag and start electrolysis. I've never worried too much about it, because if the saw is going back into service, then the movement of fuel/oil mixture will help mitigate the corrosive reaction that was allowed to occur. I've done the JB Weld thing, I've done the prime and paint thing, and I've done the marine epoxy thing on white death on the exterior of a case.

Sure is....but ask anybody that owns an old airplane about it....
