When you wear glasses, they accumulate oils from your face. Some of these oils are produced naturally by your skin, while others can come from moisturizers and makeup. When oils interact with metal eyeglass frames, a green residue may form. Cleaning your glasses every night can help prevent the residue from accumulating.

Fill a bowl with warm water. Add a small amount of mild liquid soap, such as dish or laundry detergent.

Dip a clean cloth into the soapy water. Wring the cloth to remove excess moisture.

Wipe the eyeglass frames with the soapy cloth. Light rubbing will remove the green residue.

Dampen a soft cloth with cool water. Squeeze to remove excess moisture.

Wipe the eyeglass frames to remove any soapy residue.

Dry the eyeglass frames with a towel.
