Ultrasonic cleaners utilise a process called cavitation. Here’s how it works:
-
High-Frequency Sound Waves
The cleaner’s electrical generator emits a high-frequency signal. This signal activates transducers attached to the tank, producing compression waves in the cleaning solution. These sound waves typically operate in the range of 20 kHz to 400 kHz, with lower frequencies suitable for heavy-duty cleaning and higher frequencies ideal for delicate items.
-
Cavitation
The compression waves create microscopic vacuum cavities or bubbles within the liquid. When these bubbles collapse or implode, they generate extreme localised conditions — pressures of up to 20,000 pounds per square inch and temperatures reaching around 5,000°C on a microscopic scale. This violent implosion is what effectively dislodges dirt and contaminants from surfaces.
-
Thorough Cleaning
The collapsing bubbles release intense energy that removes dirt, grease, and other contaminants from every surface of the submerged items, including difficult-to-reach crevices and blind holes. This non-abrasive cleaning method preserves delicate parts while ensuring a deep clean.
Maximising Cleaning Efficiency
To achieve the best results with ultrasonic cleaners, consider the following expert tips:
- Fully submerge items in a specially formulated cleaning solution tailored for ultrasonic use, enhancing cavitation and cleaning power.
- Use de-ionised, demineralised, or distilled water as your base liquid. Tap water can introduce impurities such as calcium carbonate, causing limescale buildup and reducing cleaning effectiveness.
- Maintain the correct bath temperature, typically between 40°C and 60°C, depending on the items and cleaning solution.
- Regularly change the cleaning solution to avoid contamination and ensure consistent results.
Before and After Ultrasonic Cleaning
Ultrasonic cleaning dramatically improves cleanliness. Items transition from visibly dirty to spotless, with microscopic contaminants completely removed. This level of cleanliness is essential in precision industries such as medical, jewellery, and electronics manufacturing.
Choosing the Right Ultrasonic Cleaning Solution
The cleaning solution is crucial in optimising ultrasonic cleaning performance. Different applications require tailored formulations:
- Engine parts and carburettors: Use degreasing solutions designed to dissolve oil, grease, and carbon deposits effectively.
- Jewellery: Use gentle, jewellery-specific cleaners. Note that ultrasonic cleaning may damage soft or porous gemstones like opals and pearls, so always consult a jeweller before cleaning valuable pieces.
