Is simple green pro hd safe to use in an ultrasonic cleaner on Dam Quick Painted parts? how about aluminum parts? Thanks.
No, it will harm and soften the paint —
Purple degreaser is even worse.
Best solution in the US cleaner is HD Dawn dish soap, warm water, then afterwards while still wet — a toothbrush.
For bare aluminum — SG is fine.
I use stronger solvents and thinners for all steel, copper, aluminum, chromed, and alloy parts.
Any plastic parts such as crank knobs, drag knobs, spools, etc. — just dish soap.
And, caution must be used when using flammables in a US cleaner (separate glass uncovered container, clear and clean area, basic safeguards, etc.).
If not confident or sure — do not attempt it.
I have been doing this for over 20 years with no issues — however, I am as careful with the process and cleanup as I was when I first started using the US cleaner. No shortcuts, proper care and storage of solutions, clean up each day, etc..
Many times with solvents like lacquer thinner, or mineral spirits — if the time allows, I will just soak the parts overnight — then US clean the next day. Mostly don't have the time to do this though —
Best,
Fred
Thanks Fred, great info.
