1. Drop into clean water when the power is on;

3.Put it under a slight heat source such as a desk lamp or spotlight to let the moisture slowly dissipate. This process takes more than six hours. Do not rush to use strong heat sources such as hair dryers. Blow it and it's over.

After these three steps of processing, the power supply can basically work normally.

2. Drop into non-corrosive liquid in the case of power failure.

3.If there is something left on the screen and it is very serious, do not deal with it according to point 1, paragraph 3, because although the electronic circuit can work normally, the screen may be quite ugly. It can be sent to the nearest maintenance department for processing or dismantling the machine for cleaning by yourself.

If you have poor hands-on ability, you should still repair it for a professional).

3. Falling into non-clean water when the power is on, or falling into corrosive liquid or viscous liquid or other clean liquids regardless of whether the power is on or not.
