A Our instructions indicate that you need to consult the optical shop where you bought the coated glasses before using them. Generally, there are coatings, and blue films are not recommended for direct use.

A Ultrasonic cleaners can be used to clean certain food-related items such as kitchen utensils, but it is important to use a food-safe cleaning solution and to thoroughly rinse the items after cleaning to remove any residual cleaning solution.

A Yes, ultrasonic cleaners are commonly used for cleaning medical and dental instruments, as they can effectively remove contaminants and are less likely to damage delicate instruments than traditional cleaning methods. However, it is important to follow proper sterilization procedures after cleaning to ensure the instruments are safe for use.

A Ultrasonic cleaners can effectively remove many types of contaminants, including bacteria and viruses. However, it is important to follow proper sterilization procedures after cleaning to ensure that all pathogens are eliminated.

A Generally speaking, the cleaning effect is not as good as that of large ultrasonic cleaners. Although part of it can be cleaned and filtered, small ultrasonic cleaners do not have an ozone function and cannot effectively degrade pesticide residues in vegetables. Professional fruit and vegetable cleaners use the principle of ultrasonic waves and ozone to remove up to 98% of pesticide residues on food effect.

A Glasses, jewelry, and watches can be washed directly with tap water and detergent.
When washing the glasses during use, place the lens facing up to avoid friction between the lens and the bottom of the machine.
Generally, we recommend only washing the strap part of the watch. The watch is a precision instrument. Even if it is waterproof, it is not recommended to wash it directly. If it needs to be used with a watch stand, you can also replace the normal temperature water with warm water for use, and the effect will be better.

A Ultrasonic waves have an effect on the dirt and dust on the surface of the object, and some processes such as electroplating or passivation will not affect it. If you are worried about washing, you can choose an upgraded version with two levels of power, and then the washing time It can be shorter, wash it for a few seconds, take it out to see the cleaning effect, and then decide whether to continue washing.

A Flammables or solutions with low flash points should never be used. The energy released by cavitation is converted to heat and kinetic energy, generating high temperature gradients in the solution, and can create hazardous conditions with flammable liquids. Acids, bleach and bleach by-products should generally be avoided, but may be used with indirect cleaning in a proper indirect cleaning container, such as a glass beaker, and appropriate care. Acid and bleach will damage stainless steel tanks, and/or create hazardous conditions.
