Ultrasonic cleaning follows a simple yet highly effective three-step process that ensures contaminants are removed. This method delivers consistent results across a wide range of materials and applications, and can safely be used on fragile items, including jewellery and electronics, provided they can handle exposure to liquids.
The first step is to prepare the cleaning solution and the items being cleaned. A suitable liquid, such as water mixed with a specialised detergent, is selected based on whether the contaminant is grease, dirt, or carbon deposits.
The item should then be placed into the ultrasonic tank, fully submerged. If you have a large ultrasonic cleaner like the examples here https://www.hilsonic.co.uk/, or you have smaller items, you can do more than one item at a time. However, you must ensure the tank isn’t overcrowded.
Cleaning
Next comes the active cleaning phase, which uses a process called cavitation. During cavitation, high-frequency sound waves pass through the liquid, creating microscopic bubbles that rapidly form and collapse. This generates tiny shockwaves that lift contaminants from surfaces, including tight crevices and intricate details.
The duration of this stage depends on how dirty the items are, but most cleaning takes just a few minutes.
Rinsing and Drying
The final step of ultrasonic cleaning ensures that any remaining residue or cleaning solution is removed. You can do this by rinsing the items in clean water, then washing away any loosened debris and detergent.
After rinsing, thorough drying using air drying, soft cloths, or specialised drying equipment is essential to prevent water spots or corrosion.
