Wipe the front and back of your glasses with a sponge full of warm, soapy water. Use a soap that does not contain anti-bacterial products. Handle your glasses gently to avoid bending them or adding scratches.
Rinse your glasses with warm water. If needed, repeat the washing and rinsing process.
Use a soft, clean cloth to thoroughly dry your glasses. Be sure not to use paper towels or facial towels to dry your glasses, as these can scratch the lenses.
