I'm on the U S cleaner wagon. I have cleaned tuning caps, trimmers, tube sockets, knobs, etc in that thing. Basically anything I can get into the tank. Its also good for glasses, watches, jewelry and other stuff. Also empty brass for reloading, model engine parts and gun parts. You don't have to use water either, it can be a solvent but you have to be careful whether the solvent will attack the plastic parts of the cleaner. I found that you can put water in the tank, put the parts and solvent in a smaller container and let it float around in the water while you run the cycle. Works great.
One other thing, it will take the paint off a dial scale so be careful with that. Don't ask how I know that tidbit.

Ive found rather good results using cheap toothpaste, it usually has more grit. Using a dremmel tool with only a buffing wheel, it seems to get them rather good. Then a light jewelers rouge for final polishing. I tend to rub then down with boiled linseed oil afterwards, it seeps in and when wiped off, theyre shiny and new looking.

Toothpaste worked like a charm on some knobs from a Philco 40-180. Nice trick. Thank you.

Drop my knobs in the tank along with some cleaner and let it do its job.

Me too, except my ultrasonic is not a Harbor Freight, but similar. It works very nicely on knobs. Gets all the little details clean. I use a bit of LA Awesome cleaning solution in distilled water.

I use an electric toothbrush and ammonia. Works really well for me. Just donā€™t get it mixed up with your other dental electric brush. :wink:

I'm just curious how much of the LA Awesome cleaning solution you're using, as in a few drops or 25% or ??? I have a Harbor Freight cleaner and I just picked up some LA Awesome cleaning solution yesterday at the dollar store.

I learned this tip here. Use denture cleaning tablets. I put just enough hot water in a cup to cover the knobs by a half inch, then a tablet or two. When I take them out, I god over them with an old tooth brush, then rince them. It works very well. Then they can be polished.

+1 on the denture tabs. Works awesome

Armor-All works amazingly well for returning panels and knobs to their original lustre....I use it a lot for that purpose...

I also use the Harbor Freight Ultra Sonic Cleaner with a little mild soap, works good.
