Simply follow these steps and enjoy the cleanest of lenses with no trace of a scratch.
- Step 1: First, rinse your sunglasses under warm water. Don’t use hot water as this could damage the coating on the lenses.
- Step 2: Take some eyeglass cleaner or, if you don’t have any, mild dishwashing liquid also does the trick. Use your fingers to wipe it all over the frames and lenses. Be extra thorough with the parts that touch your skin, such as the nose part and the temples, as these areas could be the grimiest. If fluff has built up in the hinges, a soft bristled toothbrush can fix that.
- Step 3: Rinse off the liquid soap and hopefully all the dirt and grime will be rinsed off too.
- Step 4: Use a microfiber cloth to dry off your glasses thoroughly. The best way to wipe is with a circular motion, as well as back and forth to reduce lines and smudges. A normal towel isn’t a good idea since you might end up with fuzzy lenses again.
If your glasses have rubber nose pads, and they are too dirty or are very worn down, it might make sense to just replace them.
