This and the following pics show how well this unit cleaned up.
Did This whole thing, in about 5 minutes with my pressure washer. Couldn't ask for much nicer looking radio.
Now I DID let it set out in the hot sun for a couple days to dry out. It also sat in the shop while I was working on it for a couple weeks as well.
Plenty of time for it to finish drying out.
The bottom is especially nice, looks almost new.
