You can find rubbing alcohol at department stores or by ordering it online. Rubbing alcohol can put off noxious fumes, so don’t lean directly over it as you pour it into the bowl to avoid inhaling them.
The rubbing alcohol won’t damage the frame or the hinges on your glasses.
There will be a pile of flakes that form as the coating is removed. Scrape the edge at an angle so you don’t scratch the lenses themselves.
Be sure to rub the edges where the frames meet the lenses to remove the flakes that collect in the crack.
Latex or rubber cleaning gloves will work just fine. You can find glass etching compound at hardware stores, art supply stores, or by ordering some online.
If you don’t have any cotton swabs, you can use dry paper towels.
Read the directions on the packaging of the glass etching compound for specific wait times. If the bottle says to wait 10 minutes, then wait for 10 instead of 5.
Wipe down both sides of both lenses. You may get some of the compound on the frame as you rub the lenses, so run the cloth over it as soon as you’re finished to pick up any compound that may be on it.
