How to clean dirty glasses?

The cleaning method of dirty glass is as follows:

1. Wash the glasses with warm water to remove dust and other things that may scratch the lenses.

2. Wipe the lens with microfiber glasses cloth.

3. Spray detergent on both sides of the lens. If cleaning agent is used, drop a drop of cleaning agent on both sides of the lens and then gently wipe the lens.

4. Wash the lens with water and shake off the excess water drops. If you want to avoid the watermark, you can dry it with compressed air.

Methods of maintaining glasses

First, glasses themselves are prone to static electricity. In physics, static electricity can attract light substances, dust and wool. Sometimes it happens when you just let it go. It's best to put it in the glasses case when not in use.

Second, when wiping the lens, remember not to wipe it only in one direction, and don't use force. After a long time, there will be horizontal or vertical scratches.

Third, hold the glasses and don't touch the lenses directly. People's hands have fingerprints, which are rough and have a certain amount of sweat. If you touch the lens directly, you will leave a large fuzzy fingerprint on the lens, and sometimes your nails will scratch the lens. This is a small detail that needs attention.
