    Don’t forget Q-tips and dental picks for the detail areas.

    I like flitz for detailed metal parts and chassis. I use an old ultra sonic electric toothbrush and light cotton polishing rags.

    Sounds like a little too much Cool Aid, I think.

    Sure Ya want it dry. Just don't fill up the power transformer shells, and cover the open frame types with a baggy and/or masking tape. Remove meters and known water sensitive stuff. A full sunny day of the chassis setting on one side or the other so everything is getting plenty of air, and all but the most remote areas will most certainly be dry, and unless you're a marathon kinda guy it'll be on the bench for at least a week anyway, so all the water would be gone.

    And costs a heck of a lot less.

    Brasso is a good polish, but it contains ammonia and is not all-product safe like Flitz. A milder cleaner and polish is Silvo and made by the same company.

    A great product that hasn't been mentioned yet is called "Renaissance Wax". It isn't cheap, but for a treasured item like granddad's old Hallicrafters rig, it is great stuff. It works on metals, plastics, highly polished woods, ivory, etc. It is actually used to keep museum artifacts clean and corrosion free.

    I know that the virus thing has hit that company hard, so product may be difficult to locate or scarce/non-existent.

    If you use a power washer, consider an electric model. They push out water at ~1700 to 2000 psi max. Gasoline powered models can significantly exceed that pressure rating up to and exceeding 3000 psi. Lower pressure is better.

    Eric asked;

    No sand blasting involved, just power washer.

    On my SX-16, I gave it a general rebuild and alignment. And a cosmetic job pertaining to general dents, fogged or discolored lenses, and detailing. but made no attempt to renew the chassis. It wasn't necessary. Is the chassis all pristine? No. You have to know where to stop. Now, if it had been a rat-piss rusted trainwreck, leaving pressure washing and total stripdown, then things would have maybe been different. It's now a fine radio that gives testimate to its age gracefully. The knob lettering is all hand-done. Most tedious work.
