INTRODUCTION
Use tap water. Chemical solutions are unnecessary in most cases.
Principles of ultrasonic cleaning:
Millions of tiny air bubbles are generated inside the liquid by high frequency vibration.
The air bubbles bust inside the liquid and shake off the debris to achieve the cleaning effect.
Purified water or distilled water has the same cleaning effect as regular tap water
for ultrasonic cleaning. Therefore using tap water is sufficient.
When cleaning silver or copper items where oxidation has darkened the items,
special solutions need to be added to the water to remove the oxidation.

Items Not Suitable For Ultrasonic Cleaning
2
Soft Jewelry:
Pearls, emerald, ivory, coral, agate,
sea turtle shells, etc
Welded, Plated and Glued Items:
Welded or plated metal items, glued
items
Watches:
Except diver's watches with depth
rating over 50 m (150 ft) .
Others:
Glass, ceramic, camera filters with
preexisting cracks.
These items are not hard, so scratches may occur
during cleaning.
Ultrasonic cleaning may increase the gaps inside
the welded joints, plated coating or glued items
and may cause separation.
Because the strong penetration capability of the
ultrasonic waves, water may get into the watches
if they are not truly waterproof. Use the watch
stand we supply as a precaution.
Ultrasonic cleaning may increase the cracks
pre-existed in the coating on the glasses, ceramic,
and glass. If the items have no pre-existing cracks,
then it is okay.

Jewelry Stores, Jewelry Makers:
Jewelry stores can use ultrasonic cleaners to expand services.
Jewelry such as necklaces, diamond rings, rings, earrings can
be cleaned with tap water to recover the shine.
Jewelry makers can use ultrasonic cleaners to remove debris or
abrasive powder from work-in-process items
addition to debris. Turning on the heater will raise the water
Jewelry made with investment casting often has wax layer in
temperature, melt the wax and improve the cleaning.
Optical Stores and Labs:
Optical stores can use ultrasonic cleaners to provide valuable
services. Use ultrasonic cleaner and tap water to remove the
debris between the rim and the lenses so the eyewear gets
professional cleaning and care.
Biology / Chemical Laboratories:
Labs can use ultrasonic cleaners to clean test tubes, glass or
metal containers to remove residual chemicals and materials
that can affect the accuracy of the lab tests.
Dental Clinics:
Dental clinics can use ultrasonic cleaners to clean dental
instruments, to remove blood and small particles left on the
instruments before disinfection.
Homes:
Children and baby items: Debris left in small holes and
crevices are difficult to clean by regular means. Bacteria and
mold can develop at these locations. Ultrasonic cleaners can
remove the debris and be combined with disinfection to
achieve true cleaning.
Silverware and silver, copper, or brass decorations: Debris in the grooves and patterns are difficult to
remove by regular cleaning methods. Greasy stains can be removed by ultrasonic
cleaners with a
small amount (around 20 ml or 1 tablespoon) of dish washing liquid. For silver,
copper or brass items
with oxidation that has darkened the items, add a small amount of the
special solution that can
remove oxidation. Shininess will reappear after cleaning with
ultrasonic cleaners.
Eyewear, watch bands, shavers, razors and other household items: Ultrasonic cleaners can
be used to
clean the debris between the rim and the lenses on eyewear, between razor blades,
and on the metal
mesh of shavers to keep the blades sharp.

APPLICATIONS

Shooting Clubs
To reuse brass cartridges: Adding special acid-based solution
can make fired brass useable and like new again.
Gun cleaning and care: Cleaning guns after shooting is time
consuming. Adding special solution in the water and using
ultrasonic cleaners can complete the cleaning better, quicker
and easier than traditional methods.
Mobile Phone and Electronics Service Shops
PCB renewal: Non-operational electronics, after falling into
water, or non-operational key pads can be cleaned with
ultrasonic cleaners and pure alcohol to recover the functions.
Watch Service Shops
Precision parts cleaning: Put small parts in a beaker made of
stainless steel or glass filled with lubricant oil, then place the
beaker inside the cleaning tank and add water. Ultrasonic

簡介
通常不需要特殊的清洗液，僅需普通的自來水
超音波清洗原理：
超音波清洗是以液體為介質，在高頻振動下產生無數的小氣泡，而這些小氣泡爆破時
所產生的能量使污垢脫落而達到清洗效果。
在超音波清洗中，使用純淨水或蒸餾水與普通自來水的清洗效果相同，因此使
用普通自來水即可。
當銀器及銅器的表面被氧化而發暗時，需在水中加入少量的有去氧化層作用的
專用清洗液，方可達到既清洗掉污垢又除去氧化層。
主要特色
清洗槽尺寸：18.3x15.3x7.7cm，可清洗的最大物品長度20.4cm，容量2000 ml
