[Boatanchors] white dust on aluminum

[John King]

I have a piece of  equipment in an aluminum case that has been in a very humid 
environment and was sweating due to condensation  in the shipping crate. The 
instrument case has suffered from the condensate. 


The aluminum, after drying, has a coat of aluminum dust or powder that needs to 
be removed. It is a very valuable instrument and can be very useful in the shop 
and shack.

If anyone can tell me how to remove the white powder that I believe to be 
oxidation, I will greatly appreciate it. Chemistry was not my strong subject. 
Come to think of it, I don't think I had a strong subject.

Assisting with your chemical expertise will be appreciated. 73, John, K5PGW
