I've taken my aileron apart and notice corrosion on the thin aluminum

taken a stainless steel brush to the surface and removed most of the
corrosion, but it's really a PITA.

Someone suggested using lye as a cleaner. Anyone have any experience
using supermarket lye in that role? - Mike

Dunk it in a concentrated solution of lye, come back in a day, and you
won't see any corrosion!

OTOH, the aluminium will have totally dissolved.

Lye as a aluminium cleaner is possible, in some very few circumstances.

I'd suggest thin aluminium parts are not one.
You might find a wirebrush in a drill is a good idea.

And if they are in fact that corroded, consider if the strength has been
affected.
