Run water in your kitchen sink. Let it run until the water is warm to the touch. Use the water to rinse any dust from both sides of your lenses.
Place a dab of dishwashing liquid on your fingers and rub them on both sides of your glasses with your fingers to remove any other smudges that rinsing did not handle.
Rinse your glasses again to remove the soap and any lingering materials. Dry the glasses with a microfiber cloth to complete the cleaning and polishing process.
