Plastic glasses can get scratched easily with everyday wear and tear. Polishing them will make scratches less noticeable, as well as prevent new scratches from forming. Fixing small scratches as soon as they appear can prevent expensive repairs. You can polish your glasses using some simple methods.
Spray wood furniture cleaner on a soft cloth and rub it onto the frame and lens of your plastic glasses in a circular motion. Wash off the spray cleaner with warm soapy water.
Spray DVD or CD cleaner on a soft cloth and rub it onto the frame and lens of your plastic glasses. Use a soft, clean cloth to buff the surface.
Put non-abrasive toothpaste about the size of a pea on a soft cloth and apply it to the surface of the plastic glasses in a circular motion. Wash the glasses with warm water, then use a clean cloth to buff the the surface.
To prevent scratches, avoid placing your plastic glasses with the lenses face down.
