on a combination washer/dryer, there's one metal part called the dryer duct, where water vapor right out of the drum is heated some more before going to cold water bath to condensate.
That vapor apparently carried a lot of soap with it, and after a few years there's almost 0.5Kg of soap there. I took it all apart for cleaning and there's soap under the paint, which is just flaking out.
I'm now removing all the paint and soap. The part is still pretty good. appears to be aluminium. and there's a heater element that goes right in it, so there's no rust showing anywhere.
Should I try to paint it again? with what kind of paint?
I'm guessing that if it didn't rust with all that humid soap under the paint for all those years, that it's mostly cosmetic.
I tried to buy a new one, but it's not made any more.
