To clean sunglasses properly, rinse them under lukewarm running water first, add one drop of plain dish soap, rub gently with your fingertips, rinse again, and dry with a clean microfiber cloth. That is the whole method, and the rinse-first step is the part almost everyone skips.
Most scratched lenses were not damaged by accident. They were damaged slowly, by good intentions — a shirt tail here, a paper towel there, a squirt of window cleaner. Here is how to clean your sunglasses without wrecking them, and how to store and maintain them so they last for years instead of months.
The correct way to clean sunglasses
- Rinse first, under lukewarm water. Dust, sand, salt, and pollen sit on the lens as hard little particles. Running water floats them off before your fingers or a cloth can drag them across the surface. Skipping this step is how scratches happen.
- Add one drop of plain dish soap. Put it on your fingertip, not directly on the lens. Plain means plain — no degreaser boost, no moisturizing additives, no bleach, no citrus scrub.
- Rub gently with your fingertips. Both sides of both lenses, the nose pads, the temple tips, and the little gap where the lens meets the frame. Your fingers are softer than any cloth you own.
- Rinse thoroughly. Leftover soap dries into streaks and film. Keep the water lukewarm.
- Dry with a clean microfiber cloth. Clean is the operative word. A microfiber cloth carrying yesterday's grit is a piece of sandpaper.
Do this a couple of times a week if you wear them daily, and after every trip to the beach, the boat, or anywhere with salt and sand. It takes about thirty seconds.
The mistakes that destroy lenses
Dry-wiping with a shirt tail or paper towel
This is the number one lens killer. A dry lens has grit on it, and your shirt presses that grit into the coating and drags it in circles. Paper towels and tissues add their own problem — they are made of wood fiber, which is harder than the soft coatings on a modern lens. The result is a haze of fine micro-scratches that you notice most when driving into low sun.
Household glass cleaner, ammonia, or alcohol
Window cleaner is formulated for bare glass, not for coated polycarbonate. Ammonia and alcohol strip anti-reflective and mirror coatings, leaving cloudy patches and crazing that cannot be repaired. The same goes for acetone, all-purpose sprays, and hand sanitizer.
Hot water
Hot water can soften frame materials and stress the bond between the lens and its coatings. Lukewarm is all you need — soap does the work, not temperature.
The car dashboard
A parked car in a Florida summer turns into an oven, and the dashboard is the hottest surface in it. Heat warps frames out of alignment, loosens lens fits, and delaminates coatings. If you take your sunglasses off in the car, put them in the glovebox or the center console, not on the dash.
Setting them face-down on a table
Every restaurant table, counter, and workbench has grit on it. Lens-down means that grit is now in direct contact with the part you look through. Fold them and lay them on their side, or better, put them away.
Pushing them up onto your head
It is the most natural habit in the world and it slowly ruins fit. Your skull is wider than your face, so parking sunglasses on your head stretches the temples outward. Once they are stretched, the glasses slide down your nose, and sunscreen and hair product get onto the lenses on the way past.
Storage that actually protects them
Every Vitality frame ships with a microfiber cleaning case, and it is worth keeping. It does two jobs at once — the outside protects the frame, and the inside is the cloth you clean with. Slide them in whenever they are not on your face, and the odds of a scratch drop dramatically.
If your case has gone missing, or you would like a second one for the car or the boat bag, our accessories collection covers the basics. A retainer helps too: Floating Sunglass Strings keep your glasses hanging on your chest instead of balanced on your head, and they float if the pair goes into the water.
Wash the microfiber cloth, carefully
Microfiber works because thousands of tiny fibers lift and trap oils and dust. Once it is saturated, it just smears. Wash it in warm water with a little detergent, by hand or in the machine, and let it air dry.
The one rule: no fabric softener and no dryer sheets. Softeners coat the fibers in a waxy film that kills the grab, and from then on the cloth leaves streaks on every lens you touch with it.
Small maintenance that adds years
- Retighten the hinge screws. The tiny screws in the hinges work loose over months of opening and closing. A jeweler's screwdriver and a quarter turn every few months prevents an arm falling off in your bag.
- Rinse after salt water or sweat. Salt is corrosive and abrasive. Fresh water at the end of the day handles it.
- Keep a spare cloth where you need it. One in the car, one in the boat bag, one at your desk. Spare cloths and cases live in our sunglass accessories section.
- Keep sunscreen off the lenses. Apply sunscreen first, let it dry, then put your glasses on, and wash your hands in between.
- Open and close with both hands. One-handed removal twists the frame slightly every single time, and that is what puts a pair permanently out of alignment.
- Check the alignment. Set them on a flat table. If they rock, one temple is bent, and you can usually correct it with gentle pressure.
When a lens is too scratched to keep wearing
There is a point where careful cleaning stops helping. Hold the glasses up toward a bright window. If you see a web of fine scratches across your line of sight, or the coating has visibly clouded or flaked, they have reached the end of their useful life.
The test that matters is driving. Scratches scatter light, and scattered light turns headlights and low sun into a starburst that hides what is behind it. If you find yourself squinting through your own lenses at dusk, retire that pair for driving. Vitality's lifetime replacement guarantee, which carries a processing fee, is there for exactly this situation.
Frequently asked questions
Can I use eyeglass cleaning wipes?
Pre-moistened lens wipes are fine occasionally, especially when there is no sink around. Check that they are alcohol-free and ammonia-free, and never use one on a dusty lens you have not rinsed.
Is dish soap really safe on coated lenses?
Yes, in a small amount and in its plainest form. It is mild, it cuts skin oil and sunscreen, and it rinses clean. Avoid anything marketed as heavy-duty, antibacterial, or exfoliating.
How do I get rid of streaks after cleaning?
Streaks almost always mean leftover soap or a contaminated cloth. Rinse longer, and wash the microfiber cloth without fabric softener.
Can scratches be polished out?
Not on a coated lens. Polishing compounds and toothpaste remove the coating along with the scratch and leave distortion behind. Replacing the pair is the honest answer.
Keep them clean, keep them longer
Rinse first, use a drop of dish soap and your fingertips, dry with a clean microfiber cloth, and store them in the case instead of on your head. When a pair has finally earned its retirement, browse all Vitality collections to find the next one.
