Your Ultrasonic Cleaner is an important piece of equipment in your dental practice. We get a lot of questions about common problems that arise with general wear and tear on an Ultrasonic Cleaner. Avoiding rust films, preventing dicolouration, eliminating pinholes, dealing with erosion or just general maintenance tips. Wonder no more… read our best practices to adopt in your dental practice to extend the life of your Ultrasonic Cleaner.
How to avoid rust films?
Rust stains can be avoided by regularly cleaning the tank surface using a suitable cleaning solution such as All-in-one Enzyme Solution or Sonident to remove deposits before they have the opportunity to stain the tank surface. If stains are present, an alternative is to operate the cleaner in a heating mode with water plus the cleaning solution.
How to prevent heat caused discolouration of the tank?
This can be minimised by continuously circulating the heating bath to avoid hot spots near the heaters. A recommended practice is to turn on the ultrasound as the bath begins to heat. This helps ensure the temperature distribution is equal throughout the bath.
What causes pinholes, and how to eliminate these?
Pinholes are a serious concern, there are usually caused when metal parts are being cleaned or when metal containers are in direct contact with the tank surface. To avoid this always use a basket when cleaning such parts and be sure the basket does not contact the tank floor or walls. Highly acidic baths can also cause pinholes. If these acidic solutions are necessary they should be placed in special containers that in turn are placed in the ultrasonic cleaning tank filled with water.
What is a tip to deal with cavitation erosion that occurs around the area of transducers?
Cavitation erosion is a natural by-product of ultrasonic cleaning and depending on how the units are used, will sooner or later occur to the point where the tank will leak. To postpone this we recommend regular tank cleaning to remove any abrasive articles that may have fallen from objects being cleaned. Ultrasound moves these particles around the tank bottom where they have the effect of small drills that damage the tank floor. Another good practice is to maintain cleaning fluids at the correct level for each particular tank.
Here are our top 6 Cleaning Tips to extend the life of your Ultrasonic Cleaner!
- Before placing instruments into ultrasonic unit clean them of all visible debris by hand washing them in a neutral pH soap
- Before placing instruments in the unit, turn it on and let it run for 10 minutes. This degases the solution removing any gas or air bubbles in the solution
- Always open all instruments so ratchets and box locks are fully exposed to the cleaning process
- Make sure instruments have plenty of room, don’t overload your ultrasonic cleaner
- Upon completion of the cycle, remove instruments immediately and rinse and dry them thoroughly
- Always follow proper dilution, never use a manual soap
- Change the solution daily or sooner if the solution appears dirty or murky
