Can anyone recommend a good ultrasonic cleaning solution. I have
tried the
ones from Rio, but I am not happy with the results. Seems like the
cleaner
has to be very hot to be effective.


I don't know of a good cleaner that cleans when cold in an ultrasonic
tank. In fact, even my solution of Household Ammonia and detergent
won't get the dirt out of the hallmark/crevices when cold.

It's got to be hot. The heat itself softens the dirt, then the
solution finishes it.
