Keep your glasses free of grime and scratches with proper cleaning. If you use a product designed for cleaning glasses, follow the directions on package, which usually recommend spraying it on and gently wiping it off. Mild dish soap also makes an excellent cleaner for eyewear. Wet your glasses, put a dab of soap on your finger and lather up the lenses before rinsing them in running water.

Drying Glasses and Things to Avoid

After washing your glasses with dish soap or a specialized cleanser, dry them with a microfiber cloth. Never use a napkin or paper towel to dry -- they may irreparably scratch the lenses. Wash the microbfiber cloth regularly as well, as it will accumulate dust and dirt that may damage your glasses. Don't use vinegar, ammonia, bleach or window cleaner to wash your specs, as they can ruin lens coatings.
