The glasses as myopic people wear every day, is the need for regular cleaning and maintenance, if the maintenance is not good, easy to accumulate stains and generate copper green. At home, you can use the ultrasonic cleaning machine for cleaning and maintenance, ultrasonic cleaning is a professional cleaning tools for glasses cleaning, optical stores basically have this cleaning tool, more convenient and hygienic to use at home.

Ultrasonic cleaning machine to remove copper green use method.

Tools, materials: an ultrasonic ultrasonic cleaning machine, a glasses, a bottle of glasses special cleaning agent

1, the prepared glasses ultrasonic cleaning machine placed on a flat table, open the top cover of the cleaning machine, into the glasses (note that the lens must be placed facing upward to prevent the lens contact bottom scratching.)

2, in the cleaning box filled with water, (tap water can be) pay attention not to exceed the highest water level line. You can add 1-2 drops of special cleaning agent for glasses to the water;
