The Owner of the Optical Store Does This Secretly  (Dirt and Scratches Disappear) 

Believe it or not, the humble potato is a secret weapon for keeping your glasses and optical items clean and scratch-free. Optical store owners have known this trick for years, and now you can, too!

The Magic of Potatoes
Potatoes contain natural enzymes and starch that can help remove dirt and reduce the appearance of scratches on glass surfaces. This simple, natural method is an affordable and effective way to maintain your lenses.

How to Use Potatoes for Cleaning
Choose the Right Potato: Select a fresh, raw potato. Any variety will do, as long as it’s firm and free of blemishes.
Prepare the Potato: Cut the potato in half. You’ll only need one half for the cleaning process.
Rub the Potato: Take the cut side of the potato and gently rub it over the surface of your glasses or optical items. Make sure to cover the entire lens, applying light pressure to avoid causing any damage.
Let It Sit: Allow the potato juice to sit on the lenses for a few minutes. This gives the enzymes and starch time to work their magic.
Wipe Clean: Using a soft, lint-free cloth, gently wipe the lenses clean. You should notice that dirt and minor scratches are less visible.
