How to Clean Sunglasses?

July 31, 2025

Gently rinse your sunglasses under warm tap water to remove any dust and sand. Then, lather a mild, low-pH liquid soap with a few drops of water in your hands and apply it to the lenses in circular motions. After gently rubbing the soap, rinse again with water and dry the lenses without leaving streaks using a microfiber cleaning cloth. Absolutely avoid using rough surfaces like newspaper, paper towels, or cotton swabs, as well as acetone, cologne, or alcoholic solvents. These will damage the coating and accelerate the formation of scratches.

Use the same soapy water method to clean dirt accumulated on the frame and hinges, or apply a special lens spray available from a pharmacy. After cleaning all surfaces, check the hinge screws and tighten them if necessary. Always store your glasses in a sturdy case to protect them from impacts and extreme heat or cold. Regular cleaning and proper storage will both prolong the life of your lenses and preserve their UV filter performance.

What are the methods for cleaning sunglasses?

Sunglasses are essential for both our style and eye health. Dust, fingerprints, and oil residue accumulate on the lens surface over time, reducing visual quality and decreasing the effectiveness of UV protection. Therefore, knowing the correct cleaning methods will both extend the life of the lens coatings and ensure clear vision every time you wear them.

The most common methods for cleaning sunglasses are as follows:

Lukewarm water and pH neutral soap.

As a first step, hold your glasses under warm running water. Fingerprints and grease stains are most gently removed with low pH, fragrance-free, and colorless liquid soap. Lather a few drops of soap in your hands and apply it to the lens surface in circular motions. This will loosen the dirt without damaging the surface.

After applying soap, rinse the goggles thoroughly again with lukewarm water. Make sure no soap residue remains on the lenses. Finally, dry the lenses with a microfiber cloth to remove any streaks or scratches. Avoid harsh, chemical substances such as acetone, cologne, newspaper, or cotton rags, as these can damage the coating and accelerate the formation of scratches.

Rinse with pure water.

If you're looking for a quick clean without using chemical products, just plain water is an effective method. Gently rinse the goggles under running water to remove dust and sand particles from the surface. This prevents scratches that dry cleaning might cause because it removes hard particles.

After rinsing, dry again with a microfiber cloth. If tap water is hard and contains limescale, using drinking water will prevent staining. This simple method is safe and practical if you don't have soap or spray available.

Drying with a microfiber cloth.

Microfiber cloths are designed to collect dust and fine dirt from eyeglass lenses without scratching them. After cleaning, make sure the cloth is dry and clean. If particles accumulated on the cloth rub against the surface again, they can cause scratches.

Regular washing of these cloths is important for hygiene. If possible, clean them by hand or in a washing machine using a mild detergent. A dirty microfiber cloth can be as harmful as improper cleaning, so take good care of it.

Special Eyeglass Cleaning Sprays

In environments where access to water is difficult, such as during travel or in the office, specialized eyeglass cleaning sprays offer a practical alternative. Simply spray the product onto the glass surface and wipe with a microfiber cloth to quickly complete the cleaning. These products generally have formulas that won't damage the glass coating.

Portable wipes and spray sets are always ready for use without taking up much space in your bag or car glove compartment. These specialized products are especially reliable for ensuring clear vision on polarized or anti-reflective coated lenses.

How to Clean Eyeglass Lenses Without Scratching Them?

Dust, sand, and other hard particles on the lenses should first be gently rinsed under warm running water to prevent scratching. Then, a very small amount of unscented, lotion-free dish soap should be applied to both surfaces of the lenses using your fingertips in a gentle circular motion. This will loosen the layer of grease and dirt. Finally, the lenses should be rinsed thoroughly again under running water without using a scouring pad, ensuring that no soap residue remains.

Once rinsing is complete, the glasses should be gently shaken to remove water droplets, and then thoroughly dried with a clean, dry, and soft microfiber cloth. Avoid using lint-free or harsh surfaces such as paper towels, t-shirts, tissues, or cotton rags. These materials can cause scratches, even microscopic ones, and damage the lens coating.

How to Clean Polarized Sunglasses?

To clean polarized lenses without damaging the delicate polarization film, first gently rinse the lenses with lukewarm running water. This pre-rinsing removes dust and sand particles that can increase the risk of scratching during wiping. Then, apply a mild lens spray suitable for eyeglass cleaning (containing no alcohol or acetone) or a drop of unscented dish soap to both lens surfaces and loosen oils and stains with your fingertips using circular motions. Finally, rinse thoroughly with lukewarm water again, shaking off excess water droplets.

After rinsing, dry the lenses thoroughly with a clean, soft microfiber cloth. Paper towels, tissues, or harsh fibers from clothing should absolutely not be used, as they can cause micro-scratches on the glass surface. Hot water, alcohol-based or ammonia-based cleaners weaken the polarization coating; avoid these. Always store your goggles in their protective hard case after cleaning, and regularly wash the microfiber cloth to prevent dust and sand buildup.

Tips for Cleaning Sunglasses

Proper cleaning extends the life of both lenses and frames, ensuring smooth and clear use of your sunglasses. The following tips will prevent scratches on polarized, glass, or plastic lenses while providing a hygienic user experience.

Let's offer some tips for sunglass care and cleaning;

Pre-rinse with lukewarm water.

Hard particles like sand, dust, and dirt on the lens surface can cause scratches if wiped directly. Therefore, first gently remove coarse dirt by rinsing the goggles under warm running water. This pre-rinsing makes subsequent cleaning steps both more effective and safer.

Use mild soap or lens spray.

Choose a mild dish soap that is fragrance-free and does not contain alcohol or acetone, or special lens sprays sold in optical stores. Apply one or two drops of the product to both lens surfaces and gently clean with your fingertips using circular motions. This will easily remove oil stains and fingerprints.

Drying with a microfiber cloth.

During the drying process, fibrous materials such as paper towels, napkins, or clothing can cause micro-scratches. You'll get the best results using a microfiber cloth, known for its soft texture and lack of lint. Gently press the cloth to dry the lenses without streaks or scratches.

Avoid harsh chemicals.

Alcohol, acetone, ammonia, and aggressive components in glass cleaners can damage the lens coating, leading to dulling or flaking over time. Instead, rely on a combination of water and mild soap and avoid using chemical cleaners.

Regular maintenance and proper storage.

Placing your glasses in their case after each use prevents dust and scratches. Wash your microfiber cloth regularly to prevent sand and dirt buildup. This will extend the life of both your glasses and the cloth. Proper storage is just as important as proper cleaning.

How should eyeglass cleaning spray be used?

When cleaning your glasses, ensure the spray you use is optically compatible and has an alcohol-free and acetone-free formula. Before using the spray, gently rinse the lens surface with warm water to remove any coarse particles. Spray each lens surface 2-3 times from a distance of 10-15 cm; this will ensure the liquid spreads evenly across the entire surface and loosens stains. Avoid spraying directly onto frame hinges or folding areas, as this can damage the lubricating grease and seals in these areas.

After spraying, gently wipe away excess liquid with a clean, dry microfiber cloth using circular motions, without pressing too hard. Pat dry gently, not by pressing. This ensures complete liquid absorption, a streak-free finish, and protection of polarized or UV coatings. Afterward, rinse your cloth thoroughly with mild soapy water and let it air dry to minimize the risk of microscratches during the next use.

Things to Avoid When Cleaning Eyeglasses

Small mistakes made while cleaning eyeglasses can damage both the lens surface and the coating. Here are the main incorrect practices you should avoid during this process:

Dry Wiping: If the lens surface is wiped directly while it is not damp, dust and sand particles can cause microscratches. It is important to rinse with warm water first to remove coarse dirt before proceeding to the drying step.
Using Paper Towels or Napkins: Paper-based products leave lint and their rough texture can scratch the surface. Use only a lint-free, soft microfiber cloth for cleaning. Otherwise, the clarity of your glasses will decrease over time.
Rinsing with Hot Water: Very hot water weakens the UV or anti-reflective coating on lenses over time. Always use lukewarm running water. Very cold water is also ineffective at dissolving stubborn dirt.
Avoiding Ammonia and Alcohol-Based Cleaners: Household glass sprays, vinegar, or alcohol-based products can erode coatings and cause dulling. Only use specially formulated lens cleaners available from optical stores.
Spraying Lens Spray onto Frame Hinges: Spraying lens spray directly onto the hinges will damage the grease and seals on the mechanical parts. Apply the spray only to the lens surface and gently rinse the frame with warm water if necessary.
Do not reuse a cleaning cloth without washing it: Dirty cloths re-apply old particles that have accumulated on the surface during cleaning. After each cleaning, wash the microfiber cloth with mild soap and water and dry it.
