Quick summary
To clean your eyeglasses properly, use a microfiber cloth to gently remove dust and fingerprints. Wash the lenses with lukewarm water and mild soap to remove stubborn smudges, avoid using harsh chemicals or rough materials. Regular cleaning helps maintain clarity and prevents damage to the lens coating. For a detailed step-by-step guide, read the full article below or explore our Lensotic blog for more tips.
Smudged lenses are annoying, but scratched lenses are way worse. Cleaning them safely can prevent premature replacement.
Most scratches result from wiping dry lenses with the wrong material. Dust particles act like sandpaper when you rub without rinsing first. Paper towels, tissues, and clothing all scratch over time, even when lenses look clean.
Here’s the safe method that protects your lenses and keeps them clear.
Keeping your lenses clean helps maintain clear vision and prevents scratches. If you wear your glasses all day, choosing lighter frames can also improve comfort and reduce pressure on your nose and ears. Explore our lightweight prescription glasses.
What you need
Keep these items handy, so you don’t improvise with your shirt:
- Mild dish soap (lotion-free)
- Clean microfiber cloth
- Lukewarm water
- Optional: lens cleaning spray designed for eyeglasses
- Optional: soft toothbrush (reserved only for glasses)
- Optional: cotton swabs for nose pads
Skip household glass cleaners, paper products, and hot water. These damage lens coatings.
The best daily method: soap and water
This five-step routine takes 60 seconds and prevents most scratches.
Step 1: Wash your hands
Wash your hands with soap and water, then dry them fully. Grease on your fingers transfers directly to the lenses.
If you are cleaning over a hard sink, lay a clean towel at the bottom first. This is not about hygiene; it is about reducing the chance of chipping a lens or frame if you slip.
Step 2: Hold the glasses the right way
Hold the glasses by the frame, ideally by the sides. We advise holding the side of the frame you are cleaning to help avoid warping or breakage.
Try not to grip the lenses. Fingerprints undo your work.
Step 3: Rinse under lukewarm water
Hold glasses under a gentle stream of lukewarm tap water for 10-15 seconds. This floats away dust particles that would scratch when you rub.
Never use hot water. Heat permanently damages anti-reflective and other protective coatings.
If you were in dusty conditions, rinse for about 30 seconds on each side.
Step 4: Add one small drop of soap
Put a small drop of mild washing-up liquid on your fingertip and spread it across both sides of each lens.
Eyewear manufacturer guidance describes lukewarm running water and a drop of pH neutral washing up liquid as a good cleaning combination. Optometry guidance also recommends washing glasses with a mild soap and water approach and avoiding paper products.
Avoid soaps with moisturisers. They can leave a film that causes haze.
Step 5: Rub gently with your fingertips
Rub for 10 to 20 seconds per lens side.
Use a repeatable pattern so you do not miss edges.
- Start at the centre.
- Make small circles outward.
- Trace the rim where oils build up.
Then clean the frame with the same soapy fingertips. Spend time on these spots.
- Nose pads and the bridge
- The inside of the temples
- The temple tips behind your ears
- The top bar if you have it
Manufacturers recommend cleaning nose pads and frame sides from time to time for hygiene and because removing greasy buildup can help prevent slipping.
Step 6: Rinse thoroughly
Rinse until there is no slippery feel and no visible foam. Leftover soap dries into streaks.
If your tap water is very hard and you get water spots, do one of these.
- Do a final rinse with distilled water.
- Blot more carefully before wiping.
Step 7: Shake, blot, then wipe dry
Shake glasses gently to remove excess water. Then dry with a clean microfiber cloth using this technique:
- Blot first: Press the cloth lightly against each lens to lift water droplets
- Wipe second: Use straight strokes from top to bottom
- Dry the edges: Use a clean corner of the cloth for the rim and frame groove
Never use paper towels, tissues, napkins, or your clothing. These materials scratch lenses and wear down protective coatings over time.
How to deep clean nose pads and hinges in detail
If your lenses look clean but your glasses still feel dirty, the problem is usually the nose pads and hinge area. Sweat, skin oil, sunscreen, and makeup collect there and transfer back onto the lenses.
Do this deeper clean one to three times a week.
Step 1: Do the everyday clean first
Start with the soap and water routine above. You want the lenses and frame broadly clean before you detail the corners.
Step 2: Detail clean nose pads
Dip a cotton bud in warm, soapy water.
- Wipe the front and back of each pad.
- Wipe the small arms holding the pads.
- Rotate the cotton bud as it gets dirty.
If you see a greenish buildup, continue gently until it lifts. Cleaning guides recommend tools like cotton buds or a soft toothbrush for nose pads because grime hides in tight corners.
Step 3: Clean around hinges and screws
Use a soft toothbrush with a little soapy water.
- Brush the hinge area from the inside and outside.
- Brush the screw head lightly.
- Avoid forcing bristles into the hinge.
Rinse well after brushing. Soap trapped in a hinge can attract dust.
Step 4: Optional disinfection for pads only
Avoid using alcohol based cleaners on the lenses. Several optical sources caution that alcohol based products can damage lens coatings.
If you want to disinfect high-touch areas, some practical guides suggest using a disposable alcohol pad on nose pads only, then rinsing and drying. Keep it occasional.
Quick cleaning when you are not near a sink
The priority is scratch prevention. If the lens has visible dust, do not dry wipe.
Option 1: Pre-moistened lens wipes
Use wipes designed for eyeglass lenses.
How to use them safely.
- Blow gently across the lens to remove loose dust.
- Wipe lightly from the centre outward.
- Use a fresh wipe for the second lens if the first wipe picked up grime.
Eyewear manufacturers warn against using sleeves, ties, or tissues because they are not suitable for lens care and can cause damage.
Option 2: Lens spray plus microfiber cloth
Spray both sides, then wipe with a clean microfiber cloth. Avoid household glass cleaners because coatings can be sensitive to chemicals like ammonia.
Option 3: If you must wipe without liquid
Only do this if the lens is already visibly clean and you are removing a fingerprint. Use a very light touch and a clean microfiber cloth. If you feel any grit, stop and wait until you can rinse.
What to avoid so you don’t ruin your lenses
Most scratched lenses come from a few repeat offenders.
- Avoid paper products and rough towels: Paper towels and tissues can scratch and wear coatings over time. Eye care guidance explicitly advises against paper products.
- Avoid clothing: Even soft clothing can carry dust and tiny particles that scratch.
- Avoid hot water: High heat can damage some coatings, so stick to lukewarm water.
- Avoid harsh cleaners: Don’t use window cleaner, bleach, vinegar mixes, acetone, abrasive cleaners, or strong degreasers. Ammonia and strong chemicals can damage lens coatings.
- Avoid saliva: It is unhygienic and does not dissolve oils well, which can tempt you to rub harder.
How to keep your microfiber cloth safe
A microfiber cloth is only safe if it is clean. A dirty cloth becomes a scratch tool.
- Wash it regularly, weekly is a good baseline if you use it daily.
- Use mild detergent.
- Avoid fabric softener and dryer sheets because they coat fibers and reduce absorbency.
- Air dry or tumble dry on low.
- Store it in a clean pouch or case.
Special situations and exactly what to do
You dropped your glasses in the sand or dust
Do not wipe. Rinse for longer than usual, at least 30 seconds per side, using a gentle stream. Then do the soap routine. If you still feel grit when rubbing, stop and rinse again.
Your lenses are covered in sunscreen or oily makeup
Use the standard routine but extend the soap rub to about 30 seconds per lens side. Focus around the edges near the frame, then rinse thoroughly. If a haze remains, your cloth is probably oily. Wash the cloth and repeat the drying step.
You have anti-reflective or other coatings
Treat all coated lenses as delicate.
- Avoid hot water.
- Avoid harsh cleaners like ammonia-based products.
- Use a gentle fingertip rub and a clean cloth.
The soap and water method is widely described as suitable for coated lenses when done gently.
You are dealing with hard water spots
If you see tiny dots after drying, you have mineral spotting.
- Do a final rinse with distilled water.
- Blot more thoroughly before wiping.
- Keep your microfiber cloth very clean, as minerals and rubbing can cause faint scratches over time.
Your glasses keep slipping down your nose
Cleaning helps because oil on nose pads makes frames slide. Zeiss notes that removing greasy substances can help prevent slipping.
If slipping continues, store your glasses in a hard case when not in use and consider a professional adjustment rather than bending frames yourself.
If your lenses include special coatings or adaptive technologies, proper cleaning becomes even more important to maintain clarity and performance. Learn more about photochromic prescription glasses and how they automatically adapt to changing light conditions.
Clean the case too
A dirty case re-smudges lenses. Once a week, empty it, shake out grit, then wipe inside with a cloth dampened with soapy water. Rinse the cloth, wipe, then leave the case open to air dry.
Simple cleaning schedule
- Daily: Use the soap and water routine or a lens spray.
- Weekly: Detail clean nose pads and hinges, and wash the microfiber cloth.
- Monthly: Check screws and hinge tension. If the frame is loose, an optician can adjust it safely.
Troubleshooting
- Still seeing streaks? You likely left some soap behind or used a dirty cloth. Rinse longer, then blot before wiping. Wash your cleaning cloth.
- Tiny scratches appearing? Stop dry wiping and never use paper products. Always rinse first to remove grit.
- Frames smell or feel sticky? Spend more time cleaning nose pads and temple tips. These high-contact areas collect the most oil.
Quick checklist
- Wash and dry your hands
- Rinse glasses under lukewarm water (10-15 seconds)
- Add one small drop of lotion-free dish soap
- Rub gently with fingertips (lenses, nose pads, temples)
- Rinse thoroughly until no soap remains
- Shake off water, blot, then dry with a clean microfiber cloth
- Never use paper products, hot water, or harsh cleaners
Follow this routine and your lenses stay clear, coatings last longer, and you spend less time fighting smudges.

Frequently asked questions
Can I use hand sanitizer to clean my glasses?
No. Hand sanitizer contains alcohol and other chemicals that damage lens coatings over time. It also leaves a greasy film that attracts more smudges. Stick to mild dish soap and water for safe cleaning.
Why do my glasses get smudgy right after I clean them?
Your microfiber cloth is dirty. A cloth contaminated with old oil and dust transfers grime back onto clean lenses. Wash your clothes weekly with a mild detergent, skip fabric softener, and air-dry. Also, make sure you rinse all soap off before drying.
How do I clean glasses with an anti-reflective coating without damaging it?
Use the same soap and water method, but avoid hot water and harsh chemicals. Anti-reflective coatings are more delicate than standard lenses. Always rinse first to remove grit, use only lukewarm water, and dry gently with a clean microfiber cloth.
What’s the white buildup on my nose pads?
That’s a mix of dead skin cells, sweat, oils, and sometimes makeup or sunscreen. It’s normal but needs regular cleaning. Use a cotton swab dipped in warm, soapy water to clean nose pads 2-3 times per week to prevent buildup.
Can I use my shirt to clean my glasses if I don’t have a cloth?
Only as a last resort and only if your lenses are already clean. Clothing carries dust particles that scratch lenses when you rub. If you must use your shirt, shake it out first and use the softest part with the lightest touch possible. Better option: keep a microfiber cloth in your car, bag, and desk.
Why do my glasses fog up after cleaning?
You’re either using too much soap or not rinsing thoroughly. Soap residue causes fogging. Use only one small drop of soap, and rinse until the water runs completely clear and no longer feels slippery. If fogging continues, your water might have high mineral content, try a final rinse with distilled water.
