Question 1

Can you use water in an ultrasonic cleaner?

Accepted Answer

Whenever possible, it is best to use a water-based detergent in the ultrasonic cleaning process. Water is an excellent solvent, nontoxic, nonflammable, and environmentally friendly.

Question 2

How often should the ultrasonic cleaning solution be changed?

Accepted Answer

The frequency with which you change your solution depends on the use of your machine. For the medical fields (including dental), it is recommended to discard your solution at least once a day for instrument cleaning and after every use when performing a specialized cleaning task.

Question 3

What can you not put in an ultrasonic cleaner?

Accepted Answer

Pearls, coral, tortoise shell, ivory, shell cameos, jet, and amber should not be put in an ultrasonic cleaner. Don't use an ultrasonic machine if the gems have been impregnated or coated with oil, plastic or wax. These treatments are often used on gems such as emerald, lapis lazuli, malachite, and opal.

Question 4

How do I know if my ultrasonic cleaner is working?

Accepted Answer

There are various methods used to test the performance. One of the most common and easy to apply is “the aluminum foil test” where foil is placed on the surface of the cleaning bath. Tiny pin marks will appear on the foil as cavitation. The pattern and intensity of these marks will indicate performance efficiency.

Question 5

Are ultrasonic cleaners dangerous?

Accepted Answer

Never fill the tank of an ultrasonic cleaner with alcohol, gasoline, or any other flammable liquids. They will vaporize, and could cause a fire or explosion, or release harmful gasses into the workspace.

Question 6

What does ultrasonic cleaner do to aluminum?

Accepted Answer

That temperature range provides good microscopic cleaning energy. Higher heat may soften dirt and loosen its chemical bonds faster, but it also accelerates evaporation and can damage softer metals such as aluminum.

Question 7

Can you put plastic in an ultrasonic cleaner?

Accepted Answer

This is very important in high end cleaning systems where you want the cleanest part possible. You should always use a stainless steel basket, as softer materials will absorb the ultrasonic energy. Never use plastic or other soft materials.
