1. What is Ultrasonic cleaning?
Ultrasonic is sound generated above human audible level. In real life, high pitch sound is created by high frequency and alternatively the low and base tone is created by low frequency. Frequencies above 16 kHz in general are being considered as ultrasonic. Typical ultrasonic frequencies used for cleaning purposes are from 20 kHz to 80 kHz.
2. How sound can clean?
A physical effect called cavitations. ultrasonic generates in liquid is responsible for the cleaning process. Cavitations are formed when ultrasonic travels through liquid. When a sound wave travels through water it stretches and compresses the water medium to transmit sound. When the amplitude of such sound wave increases to a level when water cannot hold the stretch, the sound literally tears the water apart and millions of vacuumed bubbles are formed under such negative pressure. The sizes of the vacuumed bubbles increase until their equilibrium are reached, they are rapidly compress by water and create millions of tiny liquid jets. The jet actions release tremendous amount of energy stored within vacuumed bubbles. Each bubble is estimated to have a temperature of more than 5000°C and a pressure of more than 10,000 PSI at molecular level when such implosion takes place. The huge amount of pressure releases at each bubble provides an ideal physical phenomenon responsible for the effective cleaning action ultrasonic cleaner offers.
3. Can ultrasonic clean cracks?
Yes, the cavitations takes place everywhere liquid can reach. During the cleaning process the article being cleaned is submerged into water or cleaning solution, millions of micro sized bubbles created by ultrasonic are capable of reaching into fine trends or cracks to clean. This phenomenon is especially useful for efficient cleaning of intricate patterns on, for example, fine jewellery.
4. Is a higher frequency better?
This depends on what is going to be cleaned. The higher the frequency the more capable it is to remove very small particles. James Products ultrasonic cleaners have a powerful operating frequency of 42,000 Hz providing excellent cleaning results.
5. Is ultrasonic the answer to environmental-friendly cleaning for the home?
Yes as the main ingredient is tap water, we believe our range of patented ultrasonic cleaners is environmentally friendly with top quality cleaning results. No longer will home users need to use environmentally unfriendly chemical based cleaning products which in most cases do not truly clean. It is only now that the ultrasonic technology has been developed in such a way it is affordable for home use.
6. What can I clean using ultrasonic technology?
This list is almost endless. Provided the product is non porous and can normally be immersed in water almost anything can be thoroughly cleaned. Here are some examples:
7. What can I not clean?
There is very little, but if you have any doubt we strongly recommend you contact the manufacturer of the item you want to clean first. However we do know that we would not recommend the following without getting approval from the manufacturer first: Some precious stones eg, emeralds Some plastics are porous and the ultrasonic cleaning can cause some whitening
8. What cleaning solutions do I need?
Normally, the only cleaning solution required is warm tap water for all our ultrasonic cleaners. Sometimes users add a small amount of washing up liquid to help hold the dirt in the water maintaining sparkle on their jewellery or precious metals.
However, we do sell an addative to help speed up the cleaning prcess and enhance the overall results.
9. Why do I need a timer on my ultrasonic cleaner?
The length of time you clean your item relates to the quality of the finish. In most cases 3 to 6 minutes is more than sufficient however some older items will need longer to clean. To keep the antique look on some types of jewellery a 3-minute clean would be all that is required.
10. What maintenance does my ultrasonic cleaner require?
All that is required is that after use you empty the tank of water and wipe clean. Because of the power of the cleaner if you were not to empty and wipe the tank then tiny metal particles will build up and over time could pierce a hole in the stainless steel water tank rendering the ultrasonic cleaner useless.
