Try using distilled water instead of tap water, hot or cold. Your piped-in water may be alkaline enough to be causing the fog.
Taking a tangent off this thread I'd like to see pics of ultrasonics large enough to do an assembled 11-speed cassette or a 78 rpm phonodisc, maybe with links to where they're being sold?
I have a smallish one made by Kendall, takes about a quart of liquid, a major PITA to clean 'cause the tray's integral with the chassis. There's a plastic basket for stuff being dunked so all the crud that comes off parts ends up settling out into the bottom of the tray. My go-to solution is tap water and Dawn too.
Avoid acetone whenever you can (or lacquer thinner) and use proper PPE and an abundance of caution if you do; they're both nasty and way too flammable for casual purposes. Most assuredly
NEITHER is appropriate for use in
any ultrasonic device!
