Change the cleaning solution periodically. Cleaning solutions can become
contaminated with suspended soil particles which coat the tank bottom.
This coating dampens the ultrasonic action and reduces cleaning
efficiency. Certain solutions will cavitate better than others. Contact your
local distributor for further information.
Heat and cavitation increase the chemical activity of cleaning solutions.
Some materials may be damaged by this stronger chemical action. When
in doubt, test run samples of items to be cleaned.
Caustic solutions: used to remove rust from steels, metal alloy corrosion
and a variety of tenacious soils.
Solution amounts may vary. The amount you use depends on the
detergent and the type of soil to be removed. Follow instructions on the
solution container and refer to the table below for the effects of solutions
on metals.
Chemicals Harmful to Your Tank
The following chemicals will harm your ultrasonic tank and the action of
ultrasonics and higher operating temperatures will increase their chemical
activity. Do not use these or similar chemicals directly or in dilution in your
ultrasonic tank or you will void your warranty.
