Ultrasonic Cleaner

[SteelWheels]

I wonder how well paint would hold up under one of these? I clean a lot of parts that have original paint on them that I don't want to lose, but if it held up using one of these, I might follow your lead.

I would think it would depend on the solution you use.

I have a model tractor that I'm going to put paint stripper in then into the sonic cleaner to see how well it works.

I agree that a solution like water and dish soap will not hurt paint.

That is one very nice cleaner :-) money well spent!

Just don't use regular Simple Green on anything aluminum or diecast (potmetal).  Extreme Simple Green doesn't corrode or discolor aluminum.  A little pricey on amazon, but it works.  I  put the "solvent" & parts in a glass or plastic jar and then put it in the ultrasonic filled with water.  Economizes the chemical cost & minimalizes cleaning the tank.  You can also do different batches at the same time.

I never had any issues with this on my vintage fishing reels , but that little one I had only ran for 4 minute cycles which isn't long enough to have any issues.
Due to cost I mostly just end up using Dawn platinum and it has always been sufficient.
