Put on your gloves and clean away any dirt or debris from your car's headlights with your terry cloth hand towel and soapy water. Rinse away the soap and dry completely.
Put a nickel-sized amount of your plastic polish onto your clean terry cloth hand towel. Rub onto the headlight in a circular and up and down motion. Continue to rub until the polish is all gone.
With your damp hand towel, go over the entire headlight of your car. All of the film should be removed at this time.
Repeat on the other headlight.
