Ultrasonic cleaning luquids

For oily or greasy items, a strongly basic solution of almost anything would work. All you're doing is saponifying the grease into soap.

Lye would work, so long as it's dilute enough not to strongly etch the work.

Some solvents are OK, too, but watch for low flashpoints in ultrasonic gear.

The regular "purple" degreaser works well. Simple Green is one of the recommended cleaners for cleaning SCUBA regulators with an US cleaner. Most any non flammable cleaner that won't attack the SS tank or the part will work fine.

I've had luck removing stains with ammonia and dish soap. Also great to clean my glasses and the SO's jewelry

"The Kid" put carb parts out of a '65 'stang that had been in a junk yard for years in a little can of carb cleaner and held it in the tank, floating and guided by a couple strings. parts looked like new.

What about when the object is aluminum and you don't want to use a strong basic? (I found a preme-o Devilbiss spray gun at the dump that I need to clean.)
