Chemicals harmful to your ultrasonic

The following chemicals are known to cause varying degrees of
deterioration in the corrosion resistance of stainless steel
ultrasonic cleaning tanks. The chemical activity of these
materials is accelerated by the ultrasonic action that takes
place in the tank.

This list covers most common chemicals but there may be others
that will also harm your tank or your jewelry or both. When in
doubt, ask your supplier. Better yet, simply use a cleaning
solution specifically recommended for ultrasonic cleaning.

Keep in mind if you use a strong solution such as Vest-Off for
investment removal, you can use an ultrasonic cleaner PROVIDED
you place the Vest-Off in a beaker which is then in turn
suspended in the ultrasonic tank (which is filled with water).
Your castings go in the beaker with the Vest-Off and the
ultrasonic cavitation is strong enough to go thru the glass and
cavitate the Vest-Off.

Don’t rest the beaker (or anything else for that matter) on the
bottom of the tank. Use a beaker positioning cover which will
firmly hold the beaker suspended in the tank so it wont tip over
or touch bottom.
