I'm getting ready to sell a bunch of parts... some are nice and clean and sparkly like they were new. Other are tarnished, grimy, but have potential.

I"m curious to know some of the recommended methods for cleaning and polishing parts... in a time efficient manner. Also is it worth it to polish parts or just let the buyer decide if they want to take it to that level.

I'm considering getting a bench top parts washer.

Before now I've been using simple green and various solvents I had in the garage like acetone, white gas, etc. in a bucket or bowl.
