Sunglasses Care: Sand, Salt, Heat and Storage

After a day outside, sunglasses may carry more than fingerprints. Sand, salt residue and dust need care before a cloth touches the lens. Follow the manufacturer’s instructions for the particular lens material and coating.

Remove loose particles before wiping

Do not rub sandy sunglasses with a shirt or towel. Where appropriate for the lenses, rinse loose debris away with lukewarm fresh water before using a compatible cleaner and clean microfiber cloth. Our daily cleaning guide covers the basic sequence.

Keep heat out of the routine

Avoid hot water, direct heat and leaving glasses in a hot vehicle. Do not use heat to dry lenses or bend the frame into place. If a frame has changed shape, get it assessed rather than warming and forcing it yourself.

Use the case, not a loose bag

Let the glasses dry appropriately before storage and keep the case free of grit. Avoid leaving lenses face down or loose with keys. Store the microfiber cloth where it will not collect sand.

Inspect persistent marks

A scratch or damaged coating cannot be scrubbed away. If haze or a patch remains after normal cleaning, stop applying pressure and ask for inspection. The smudge troubleshooting guide helps separate ordinary residue from a problem needing review.

Do care instructions change for polarized lenses?

Follow the specific lens instructions rather than assuming one cleaner suits every sun-lens treatment. Polarization is an optical feature, not a promise that a surface is scratch-proof. See tint and polarization for the difference between lens options.
