How to Clean Your Glasses Without Scratching Them
Most lens damage is not an accident. It is a shirt hem, a dry tissue and a dashboard in July, repeated a few hundred times.
The correct method
- Rinse both lenses under lukewarm running water first. This is the step that matters most — it floats away the dust and grit that would otherwise be dragged across the lens.
- Put one small drop of washing-up liquid on each lens and rub gently with your fingertips, front and back.
- Rinse thoroughly, including the nose pads and the hinges where skin oil and dust collect.
- Shake off the excess water and dry with a clean microfibre cloth, using light pressure.
What to never use
- Your shirt, tie or any clothing. Fabric holds dust, and you are grinding that dust in a circle across the coating.
- Paper tissues, kitchen roll or napkins. Paper is wood fibre — it is abrasive at exactly the scale that scratches a coating.
- Glass cleaner, alcohol, acetone or vinegar. These strip anti-reflective and hydrophobic coatings.
- Your breath. Saliva vapour leaves a film, and wiping a dry lens is what causes scratches in the first place.
Can scratches be removed?
No. Every home remedy circulating online — toothpaste, baking soda, car wax, brass polish — works by abrading the surface further. On a coated lens they strip the coating and leave a hazy patch that is worse than the original scratch. A scratched lens is replaced, not repaired.
Habits that decide how long a frame lasts
- Take them off with two hands. One-handed removal twists the frame and is the main cause of a permanently crooked fit.
- Put them down lenses-up, or better, in the case. Face-down on a table is how the centre of a lens gets scratched.
- Never leave them in a parked car. A dashboard in an Egyptian summer easily exceeds 70°C, which warps acetate and crazes coatings.
- Never push them up onto your head. It stretches the temple arms permanently wider than your face.
- Wash the microfibre cloth. A cloth that has absorbed months of skin oil and dust is no longer cleaning anything.
- Have the fit checked once or twice a year. It takes minutes, it is free at any branch, and it stops a slowly loosening frame from sliding down and misaligning your lenses.
Dust, and why it matters more here
Airborne dust in much of Egypt contains fine silica — which is harder than any lens coating. That is the entire reason the rinse-first step is non-negotiable locally: wiping a dusty lens dry is closer to sanding it than to cleaning it. Rinse daily, and keep the case with you rather than at home.
Loose hinges, a bent bridge or worn nose pads — most of these are a five-minute fix.

What is the best way to clean glasses?
Rinse under lukewarm running water, apply a small drop of washing-up liquid, rub gently with your fingertips, rinse thoroughly and dry with a clean microfibre cloth. The rinse before wiping is the critical step — it removes the grit that would otherwise scratch the lens.
Can I use alcohol wipes on my glasses?
Not on coated lenses. Alcohol degrades anti-reflective and hydrophobic coatings over repeated use, causing them to cloud or peel. Use only lens sprays labelled as coating-safe, or plain water with a drop of washing-up liquid.
How do I remove scratches from my glasses?
You cannot. Every home method — toothpaste, baking soda, polish — abrades the surface further and strips the coating, leaving haze that is worse than the scratch. Scratched lenses have to be replaced, which is usually cheaper than replacing the whole pair since the frame can be reused.
How often should glasses be adjusted?
Once or twice a year for most people, or any time they start sliding, sitting crooked or pressing behind the ears. It is a free service at any branch and takes a few minutes. A frame that has loosened lets the lenses drift out of alignment with your pupils, which causes eye strain even though the prescription is correct.
