Parts cleaners (solvent tank v. ultrasonic tank)
« on: October 10, 2023, 18:30:19 »
I'm looking at getting a tool to clean parts.  An age old tool in auto shops is the solvent tank, often includes a pressure nozzle and cleaning brush.  In recent years, hobbyists like us have been using ultrasonic tanks to clean small parts.  Does the ultrasonic tank replace the need for the solvent tank?  Should the hobbyist have both?  Solvent tanks are larger for less money.  What size and brand of ultrasonic units to you guys have?  I'm thinking 10 liter or 2.5 gallon would be minimum for our hobby, no?

Also, when the solvent needs refreshed in the old fashioned solvent tank, I assume you need to take the stuff to a hazardous waste disposal site.  Right?  How is the used water/cleaner solution in ultrasound cleaners disposed of?

Hey Rodd, it depends on what parts you're looking to clean. I have used an ultrasonic cleaner only on my carburetor parts. Engine greasy parts: brush and plenty of kerosene. Chassis/steel parts: sandblaster or wire wheel on angle grinder.

Most kitchens these days have an automatic parts washer built-in, they even pump out the waste.

Well, if I ever get to it, I want to really clean up the engine bay hardware while the engine is out.  So, that's probably a solvent tank.  Rebuilding the electric fuel pump is on my list, I think the ultrasonic tank would get those parts (housing, etc.) clean.  Fuel injectors and cold start valve would be good candidates for ultrasonic cleaning.  Who knows what else I might do.

Yes, the kitchen is not an option.  Also, we're on well and septic, so what I put in the ground may come back in my drinking water some day!  That thinking (regardless of accuracy) keeps me from polluting.

Obviously there's no one way to clean everything.

I have a small-ish ultrasonic cleaner I bought when I owned a car wash, I used it to clean a variety of small parts including nozzles. I used water-based degreasing solvents. ZEP purple is one, and you can get something similar at Sam's Club, also purple. I also used various detergents etc. depending on what was being cleaned. The unit holds maybe 24 ounces or so, and has heat. Not as big as some, but much larger than a jewelry cleaner.

I used to do a lot of degreasing for bicycle work using a tried and true old coffee can and mineral spirits. As soon as you would put in a greasy dirty object, you'd see the grease being dissolved by the mineral spirits. However in recent years with the advent of low-VOC mineral spirits, these new mineral spirits are pretty useless; I've soaked some greasy nuts and bolts for days and nothing happens! The water based purple degreasers do a better job and quicker.

Spray cans of both Carburetor and or Brake Cleaner do a good job on installed parts. I suspect that some of these volatile organic solvents are available in bulk but you then have the disposal issue you note, and I guess they are not cheap either.

I also have a vibratory tumbler. Also not too big but big enough for all kinds of small parts such as nuts and bolts and similar. After cleaning, some days in the tumbler yield a nice clean part with the right media.
