COMMON CLEANING METHODS
1
REGULAR CLEANING Only tap water is needed.
Suitable Locations: jewelry stores, optical
stores, chemical labs, dental clinics, homes.
Cleaning Method:
1. Add water to the cleaning tank to the level
between “MIN” and “MAX” lines and above the
area to be cleaned.
2. Put the items to be cleaned inside the basket
or directly in the cleaning tank.
3. Press SET button to set the timer 5 to 10
minutes. Press On/Off button to start cleaning.
Notes on using the basket:
1. The basket reduces the friction between the items
and the tank but it absorbs about 30% of ultrasonic
energy and reduces the cleaning effect.
2. When the items are relatively large and with
greasy debris, they can be put in the tank directly.
During cleaning, debris will come off the items like “smoke”. Water will become murky.
Cleaning is done when smoke is no longer visible. Replace the water to wash other items.
2
INDIRECT CLEANING Put the items in a separate container. Use ultrasonic
waves to penetrate the container to do the cleaning.
Suitable Locations: watch service shops,
printing shops, mobile phone and electronics
service shops, homes.
Different industries use different fluids to be
used inside the containers:
1. Watch service shops - Watch oil (to prevent rust)
2. Printing shops – Acetone are often used
(to dissolve ink)
3. Mobile phone and electronic service shops - Pure
alcohol (to evaporate quickly)
4. Homes - Rubbing alcohol (to remove odor, to
clean and to disinfect at the same time)
Avoid acetone from contacting the plastic housing
to prevent corrosion. Use Indirect Cleaning and a
Cleaning Method:
glass or metal container for acetone.
1. Put the item inside a container. Add proper fluid to submerge the area to be cleaned.
2. Place the container inside the basket, then put them in the tank. Add water to a level between
MIN and MAX, not over the container.
3. Press SET button to set the timer to 10 minutes. Press On/Off button to start cleaning.
Ultrasonic waves will penetrate the container and clean the item.
Selection of container:
1. Plastic containers – Plastics are soft and will absorb about 30% of ultrasound energy and
reduce the cleaning effect.
2. Aluminum containers – Absorbs about 20% of ultrasonic energy.
3. Stainless steel containers – Absorbs about 8% of ultrasonic energy.
