The opticians were really upset when they chose the ultrasonic cleaning machine. The brands of ultrasonic cleaning machines on the market are really varied and dazzling. As a person who has worn 10 glasses for more than five years and washed them with an ultrasonic cleaner, I have suffered more than anyone else on the road of choosing an ultrasonic cleaner. A good ultrasonic cleaning machine has good compatibility, and there are many items that can be cleaned. Not only can you clean glasses, but many ultrasonic cleaning machines can clean small objects such as rings, earrings, cosmetic brushes and braces. It also has the function of ultraviolet sterilization. So there are so many ultrasonic cleaning machines on the market, how can we choose a good ultrasonic cleaning machine?

First, how to choose and use ultrasonic cleaning machine?

1, working frequency: the cleaning power of general ultrasonic cleaning machine depends on the working frequency of ultrasonic. Normal ultrasonic frequency is relatively normal at 20KHZ~50KHZ. Too high ultrasonic frequency may damage articles, and too low ultrasonic frequency may not achieve cleaning effect, so it is more suitable in this range!

2. Brand: You must choose the right brand when buying an ultrasonic cleaning machine. The after-sales service of well-known brands will not be bad. For example, Yi Xi ultrasonic cleaning machine has 7 days free trial service, and Meng Jie also has after-sales guarantee. When products encounter problems, there will be special after-sales solutions.

3. Water tank capacity: If you buy an ultrasonic cleaning machine to clean daily small objects, the capacity does not need to be too large. If you want to clean multiple items together, it is recommended to buy one with a capacity of not less than 200ml. If the capacity is too small, a lot of things will be cleaned. Limited, large capacity can hold more items at a time.

4. Sterilization method: Some ultrasonic cleaning machines have UVC ultraviolet sterilization method, which can sterilize articles better, and another disinfection method is to buy cleaning liquid for disinfection. Both methods can be used, mainly depending on which sterilization method friends prefer.

5. Damage or not: This requires special attention. When buying an ultrasonic cleaning machine, try to buy one with a small damage rate. Some ultrasonic cleaning machines have done the technology of damaging articles 0, which will be very good. Be sure to read the instructions of the ultrasonic cleaning machine clearly, which items can be cleaned and which items can't be cleaned, and don't blindly clean some household items.

6, look at the material: the material of the clear water tank liner is generally 304 stainless steel, which will be safer and more durable, and you can safely clean some personal items. The external machine is made of ABS material, which will be more wear-resistant!

7. Noise: The noise of the ultrasonic cleaning machine is inevitable, but you can choose an ultrasonic cleaning machine with lower noise when you buy it. The noise of our normal conversation is about 70 decibels, so try not to be higher than 70 decibels, otherwise you will feel very noisy during the cleaning process and the experience will be greatly reduced!

8. Outer cover: The outer cover of ultrasonic cleaning machine is divided into visible outer cover and non-visible outer cover. Choose an ultrasonic cleaning machine with a visible cover, and you can intuitively see a dirty thing being cleaned in a short time.
