1. Eyeglasses

Many people habitually wipe their glasses when they get dirty. If they have toilet paper on hand, they use it; if they don't have toilet paper, they use alcohol wipes, which they think is even better because alcohol is more effective at removing stains than water.

However, this method is highly undesirable. Although alcohol can remove some stains, it is not very effective at cleaning stubborn stains such as grease and fingerprints.

Furthermore, eyeglass lenses typically have anti-reflective coatings, hard coatings, and UV protection coatings. Alcohol, as an organic solvent, can dissolve and damage these coatings, leading to lens damage.

In addition, it is not recommended to wipe the temples of glasses with alcohol, especially metal frames. Once they come into contact with alcohol, they will react, causing corrosion to the surface of the frame, resulting in mottled spots or discoloration, which will affect the appearance and durability.

Recommendation: Cleaning glasses is actually done with water. If you feel that water is not enough, dish soap, a neutral detergent that everyone has at home, is also a good choice for cleaning glasses. Of course, if your glasses are expensive enough, you can also buy a special glasses cleaner.
