Here’s a simple, optician-approved way to deep clean glasses (lenses and frames) plus a bit of “forum wisdom” on more intensive options and what to avoid.

Quick Scoop

  • Rinse with lukewarm water to remove grit (prevents scratches).
  • Wash lenses and frames with a tiny drop of mild, lotion‑free dish soap using your fingertips.
  • Clean nose pads and hinges with a soft brush, then rinse well.
  • Dry with a clean, lint‑free towel and finish with a microfiber cloth.
  • For a “deep clean,” consider popping lenses out or using an ultrasonic cleaner at an optical shop or jeweler.

Step‑by‑step: Deep Clean at Home

1. Prep your hands

  • Wash hands with liquid, oil‑free soap and dry them with a lint‑free towel.
  • This keeps skin oils and tiny grit from going straight back onto your freshly cleaned lenses.

2. Rinse off dust and grit

  • Hold your glasses under a gentle stream of lukewarm (not hot) water.
  • The water removes dust and debris so you don’t grind it into the lenses and cause micro‑scratches.

3. Soap wash for lenses and frame

  • Put a tiny drop of mild, lotion‑free dish soap on your fingertips or directly on each lens.
  • Gently massage:
    1. Both sides of each lens.
2. The frame front and back.

3. The nose pads and the arms behind your ears.
  • A soft toothbrush can help clean crusty nose pads, hinges, and where the frame meets the lens.

4. Rinse thoroughly

  • Rinse lenses and frames under lukewarm running water until all soap is gone.
  • Lightly shake to remove excess water.

5. Dry without scratching

  • Use a clean, dry, lint‑free towel (not one washed with fabric softener or dryer sheets, which leave residue).
  • Gently pat or wipe in straight strokes rather than harsh circular scrubbing.

6. Final polish with microfiber

  • Finish with a clean microfiber cloth designed for glasses to remove any remaining streaks.
  • Wash your microfiber cloth regularly with liquid soap and hot water so it doesn’t just smear trapped oils around.

“Deeper than normal” clean (intensive options)

These are the kinds of things people talk about in forum discussions when “regular cleaning” isn’t cutting it.

  • Pop the lenses out (for grime in the rim)
    • Some users recommend popping lenses out to clean between the lens and frame where gunk builds up.
* If you’re not comfortable, you can ask an optical store to do this so you don’t bend or crack the frame.
  • Ultrasonic cleaner (pro‑level deep clean)
    • Commenters mention ultrasonic cleaning baths at jewelers, watchmakers, or optical shops to shake out dirt from tiny crevices.
* Many optical stores will drop your glasses into their ultrasonic bath for a quick, thorough clean.
  • UV sanitizer boxes (for disinfection)
    • Some people like UV light sanitizer boxes to disinfect frames and nose pads, especially after illness, though this is more about germs than visible dirt.
  • Targeted refresh: nose pads and ear pieces
    • Replacing old nose pads and then cleaning the rest of the frame with soapy water or in an ultrasonic bath can make glasses feel almost new.

Safe extras and what to avoid

Sometimes okay (with care)

  • A little isopropyl alcohol on the frame or nose pads can help disinfect and cut oils, but repeated use on coated lenses is risky, so keep it minimal and follow your optician’s advice.

Common mistakes that can damage lenses

Avoid these because they can scratch lenses or ruin coatings:

  • Clothing (shirt corners, hoodies, etc.).
  • Paper towels, napkins, tissues, or toilet paper.
  • Household glass cleaners or multi‑surface cleaners.
  • Saliva or “quick spit‑and‑wipe” methods.
  • Hot water that can damage anti‑reflective or other coatings.

How often to “deep clean”

  • A quick soap‑and‑water clean a few times a week keeps everyday smudges and skin oils under control.
  • A more intensive clean (ultrasonic machine, lens removal, nose pad replacement) is useful if you notice trapped grime, persistent foggy patches, or irritation on your nose/ears.

Method What it does How “deep” it is How often
Lukewarm water + mild dish soap + microfiber cloth Removes everyday oils, fingerprints, and light grime from lenses and frames without harming coatings. Standard, core cleaning routine. Every day or a few times per week, depending on how quickly your glasses get dirty.
Soft toothbrush on nose pads/hinges Gets into tiny crevices where skin oils and dirt build up, especially around nose pads and frame joints. Deeper than normal fingertip cleaning. Every 1–2 weeks or when you see visible buildup.
Popping lenses out to clean frame groove (by you or optician) Removes trapped grime between the lens edge and frame rim that regular washing can’t reach. Deep clean; higher risk if done incorrectly. Occasionally, when there is visible dirt or irritation where the frame meets the skin.
Ultrasonic cleaning bath at optical shop/jeweler Uses vibration in a cleaning solution to flush out dirt from all crevices in frame and around lenses. Very deep professional‑style clean. As needed; great when glasses feel grimy even after normal washing.
UV sanitizer box Disinfects frames and surfaces, targeting germs rather than visible dirt. Deep on sanitation, light on actual “scrub.” Optional; useful during illness or if you share glasses for demos, etc.
Avoided methods (paper towels, glass cleaner, hot water, clothing) These can scratch lenses, leave residue, or damage coatings, so they are not recommended. Not safe; can shorten lens life. Never, if you want your lenses to last.
