Ultrasonic cleaner

Mon Dec 30, 2019 10:17 pm

So what are peoples favorite solutions for an ultrasonic cleaner? Straight Simple Green? Water? A mix of simple green and marine Salt-X?

CLR is available at grocery stores and some hardware stores. I have used in various percentage mixes with water in my Ultrasonic cleaner for 20 years with good results. Mix depends upon level of corrosion, but I never had to go over 50/50. Weaker mixes such as Mark suggests will work fine and just may take a little more time in the tub for tough jobs.

Ill have to check our stores. Is it safer on brass and chrome than vinegar?

Although the CLR container cautions against use on several materials, including Brass, I have tested and used it for years on Chrome plated Brass regulator parts. Before trusting CLR on expensive and/or rare regulators I did several tests using a 50/50 mix of CLR and water. In one test I submerged two extra regulator port plugs overnight in the mix with no ill effects. On a second test using the same percentage mix I left the items in for 24 hours with no apparent damage. While I did not test any extended submersion on brass with a badly damaged finished, such as flaking chrome, I would advise against doing that on a valued object with a compromised finish.

Of course I would not even recommend such lengthy soaks on good regulator components, and also suggest using a lighter mix and only for as long as necessary for a good cleanup. Usually just a few minutes in the Ultrasonic bath (or even just a plastic container) does the trick.

Vinegar and Simple Green seems to work pretty well if you don't mind smelling like a pickle after each project. For years I used a 25/75 solution of pool acid and water with pretty good results, but I think the CLR or Vinegar is a safer way to go. One caution about any of the acidic solutions is not to reuse them too many times as brass salts build up in them and can leave a thin gold or brass-colored plating/stain on a good chrome surface if you accidently leave items in for an extended period of time. Once I forgetfully left chrome plated components of a nice Calypso-J in the acid bath overnight. The next day I found a light golden colored regulator. :shock: Thankfully the owner liked the looks of it, and was actually pleased to have a regulator unlike anyone else's, so I was spared having to give him a new reg. :D

^^^ What Bill says! :)

P.S. You can order CLR from Amazon.com.too.

Ive always used 50/50 vinegar and SaltX from my boat, but I have never been imoressed with the results. However, I was also trying to clean badly corroded parts. Might still do an overnight pre soak in the salt-x.

I didn't do any testing with long submersions, but haven't had issues with short exposures. Also don't see any warning on container against using it on rubber. I generally clean up the rubber parts with Simple Green anyway.

Thanks guys. CLR worked great at 20%, and my Chinese ultrasonic cleaner worked awesome.
