How to Use an Ultrasonic Cleaner

As an introduction this post focuses on how to use an ultrasonic cleaner, not the actual cleaning process – itself a rather straightforward operation.

Proper use of an ultrasonic cleaner, regardless of its size, protects your investment in the equipment. These tips on how to use an ultrasonic cleaner are directed primarily to our readers who recently purchased equipment or are planning a purchase. Some of these tips may seem a “no brainer,” yet they are important nonetheless. When followed they contribute to a long and profitable service life for the equipment.

Cleaning Solutions and Solution Capacity

There are a seemingly endless number of ultrasonic cleaning solutions available, many for day-to-day cleaning operations and others for highly specialized cleaning tasks. In the first category iUltrasonic offers a selection of commonly used cleaning chemicals that solve a wide variety of cleaning challenges. Our professionals are ready to provide additional recommendations based on your particular cleaning challenges.

Users should avoid using highly acidic cleaning solutions that can damage tanks. Acid resistant tub inserts are available for such circumstances. Likewise users should never use volatile solvents in a standard ultrasonic cleaner. Instead inquire about explosion-proof equipment.

An ultrasonic cleaner is designed to hold a specific volume of cleaning solution. In many models this is indicated by a fill line. Observe this, or check the operating instructions, and account for solution displacement due to parts being cleaned.

Keep Parts off Tank Bottoms and Walls

Ultrasonic vibration will cause parts to wear against the tank bottom, and may eventually cause a leak. Use baskets designed for the cleaner, or otherwise suspend parts from overhead taking care they do not contact tank surfaces. Another option is a mesh platform with rubber insulated feet.

Heated Cleaning Solutions

If your cleaning solution formulation requires heating to perform the task, activate the ultrasound during heating to circulate the solution and avoid hot spots adjacent to heating elements.

Maintain Cleaning Solutions and Tanks

Contaminants removed during ultrasonic cleaning may float to the surface or sink to the bottom.  Periodically skim off the floating contaminants and set them aside for later disposal.  (Some tanks are equipped with skimmers and spray bars to accomplish this). When cleaning efficiency drops drain the tank and dispose of the spent solution, along with skimmed contaminants, according to local regulations.

Clean the tank according to user manual instructions.  Then refill it with fresh solution, degas it and you’re ready for the next projects.

Read the Instruction Manual!

Yeah, yeah, but this is good advice. Everything, well most everything, you need to know about operating an ultrasonic cleaner is explained in the instruction manual. But if there are questions or concerns, a call and a chat with our ultrasonic experts will get you the information you need.
