I wish, I could say the same. I used 5% Acetic Acid (white vinegar) on a B2, and it did NOT remove the corrosion, just made it soft, after 30 minutes in the ultrasonic bath. 25% citric acid removed it all together in about 10 minutes.
I don't understand how you can't find the MSDS of the GMC Ultrasonic Cleaner, or it's called GSMot Hydrosonic Solvent. It only takes me a few minutes to find it. Here is the link to the MSDS.

Thanks. First page -“ I use ~ 4% by volume phosphoric acid, just a teaspoon each of propylene glycol and Dawn dish detergent to a quart of water.” Not sure why propylene glycol, but dawn dish soap is a surfactant. This person appears to be on the same page as me, acid solution with a...
So what I am reading is, using GMC Ultrasonic cleaner is very bad for regulators??? The main ingredients per the MSDS is 50-70% phosphoric acid, 10-20% 2-butoxyethanol. I have used GMC ultrasonic cleaner in the past, and does a very good job, but it’s rediciously expensive. Phosphoric acid is...
