Avoid the Mistakes: How to Clean Your Glasses the Right Way

We’ve all been there — smudges, fingerprints, and even the occasional splash of sauce can obscure the clarity of our eyeglasses, leaving us squinting at the world through a foggy lens. While it may seem straightforward to swipe them clean with a shirt sleeve, proper eyewear maintenance goes beyond quick fixes.

This article delves into the most effective methods on how to clean your glasses, including a step-by-step guide, common pitfalls to avoid, and answers to popular questions like, “Can you clean glasses with alcohol?” Read on to ensure you’re seeing the world as clearly as possible.

Common Mistakes in Cleaning Eyeglasses


One of the biggest challenges in maintaining clean eyeglasses is knowing what not to do. Common mistakes can not only result in smeared and smudged lenses but can also lead to permanent damage. Here are some of the most frequent pitfalls:

  • Using a Shirttail or Rough Fabric: Although it seems convenient, the fibers in regular cloth can be abrasive, leading to fine scratches on the lens surface over time.
  • Cleaning Lenses Dry: Wiping your lenses when they are dry can rub in dirt and grit, causing microscopic scratches that accumulate and degrade vision quality.
  • Using Household Cleaning Products: Cleaners like window sprays or multi-surface cleaners often contain chemicals that can strip off the lens coatings and potentially discolor the frames.
  • Submerging in Water: While it might seem like a good idea to give your glasses a “deep clean,” submerging them in water can loosen the screws and may also damage special lens coatings if the water is too hot or chemically treated.

Understanding these common mistakes can go a long way in helping you maintain your eyeglasses in pristine condition.

The right tools are key to properly cleaning your eyeglasses without causing damage. Investing in high-quality cleaning supplies ensures that your eyewear will not only be spotless but will also last longer. Here are the essentials:

  • Microfiber Cloth: These are specially designed to lift off oils and dirt without scratching the lens. They can be washed and reused, making them eco-friendly and cost-effective.
  • Specialized Lens Cleaner: Available in spray or wipe form, these solutions are made to remove oils and debris without damaging lens coatings. Make sure to choose a product that is specifically designed for eyeglasses.
  • Soft, Lint-Free Tissues: If you don’t have a microfiber cloth, these can serve as a good alternative for wiping off cleaner. Just make sure they are free of lotions or additives that could smudge your lenses.
  • Mild Dish Soap: A drop or two of a gentle dish soap that is free from lotions and strong fragrances can be highly effective for cleaning. Some people even consider this their go-to cleaner.
  • Lukewarm Water: Always use lukewarm water, as hot water can damage lens coatings and can warp plastic frames over time.

Having the right tools on hand can simplify the cleaning process and help you avoid the common mistakes that lead to damaged eyewear.

Step-by-step Guide to Cleaning Eyeglasses


Clean eyeglasses are essential for optimal vision, and the process isn’t as simple as wiping them on your shirt sleeve. Here’s a detailed step-by-step guide to ensure you get the cleanest, clearest lenses possible:

1. Wash Hands Thoroughly

Before touching your glasses, it’s important to wash your hands with soap and water. Any oil, dirt, or grime on your hands could transfer to your eyeglasses, counteracting your cleaning efforts. Make sure to rinse and dry your hands well.

2. Rinse Eyeglasses with Lukewarm Water

Start the cleaning process by holding your glasses under a gentle stream of lukewarm tap water. This initial rinse will help dislodge larger dirt or debris particles that can scratch your lenses during the cleaning process. Avoid using hot water, as it can damage lens coatings or warp plastic frames.

3. Apply a Small Amount of Appropriate Cleaner

Put a small drop of mild dish soap or specialized lens cleaner on your fingertips. Gently distribute this soap across the surface of your lenses and frame. Be cautious not to use harsh soaps or those containing added lotions, as these can leave a filmy residue.

4. Gently Rub Both Sides of Each Lens, Frames, and Earpieces

Use your fingertips to rub the cleaner in a circular motion on both sides of each lens. Extend the same care to the frames, focusing especially on the nose pads and ends of the earpieces that touch your skin. These areas are often overlooked but can accumulate a lot of oils and grime.

5. Rinse Thoroughly

Rinse off the cleaner by once again holding your glasses under a stream of lukewarm water. Make sure to get rid of all soap residues, turning the glasses around to ensure all surfaces are rinsed. Leftover soap can smudge your lenses and create streaks, hindering your vision.

6. Shake Off Excess Water

Close the tap and gently shake your glasses to remove most of the water droplets from the lenses and frames. This action helps to make the drying process quicker and more efficient.

7. Dry with a Microfiber Cloth

Grab a clean, lint-free microfiber cloth to carefully dry your glasses. Start with the lenses, using soft dabbing motions to avoid causing scratches. Once the lenses are dry, proceed to the frame, ensuring you also dry the nooks and crannies.

8. Inspect for Smudges

After you’ve dried your glasses, hold them up to a light source to inspect for any remaining smudges, streaks, or spots. If you find any, it might be necessary to repeat the cleaning process.

Cleaning your glasses isn’t just about appearance; it’s about maintaining the quality of your vision and the longevity of your eyewear.

Can You Use Windex on Glasses?

When it comes to cleaning surfaces around the house, Windex is often a go-to choice. But should it be used on eyeglasses? The answer is generally no. Windex contains ammonia, a strong chemical that can strip away the special coatings on your lenses, such as anti-reflective and scratch-resistant layers. It can also be harsh on plastic frames, potentially causing them to become brittle over time.

Moreover, Windex is not formulated for optical clarity. While it might give your windows a streak-free shine, it’s not designed to interact safely with the materials commonly used in eyeglasses.

If you’ve been using Windex to clean your glasses, it would be wise to switch to a specialized lens cleaner or mild dish soap to preserve the integrity of your eyewear.

Can You Clean Glasses with Alcohol?

Isopropyl alcohol is often considered for cleaning eyeglasses due to its disinfecting properties and quick drying time. However, its use is not universally recommended. While it’s true that alcohol can kill bacteria and evaporates quickly, it may also strip away special lens coatings like anti-reflective or scratch-resistant layers.

Some frame materials, especially certain plastics, can also react poorly to alcohol, becoming discolored or brittle over time.

If you decide to use alcohol, pay attention to its concentration; lower concentrations (around 70%) are generally less harsh. Always check the manufacturer’s guidelines before applying alcohol-based solutions to your eyeglasses.

Although it may be suitable for occasional rapid disinfection, alcohol should not be a regular part of your eyeglass cleaning routine due to its potential to damage lens and frame materials.

What to Avoid

When it comes to cleaning eyeglasses, there are a number of things that could potentially harm your lenses and frames, reducing both their effectiveness and lifespan:

  • Hot Water: Excessive heat can damage the special coatings on your lenses and may cause plastic frames to lose their shape. Always use lukewarm water for cleaning.
  • Abrasive Cleaners: Avoid using any kind of abrasive cleaners, including baking soda or other scouring agents. These can severely scratch and damage your lenses.
  • Alcohol & Ammonia-Based Cleaners: While these can disinfect, their chemical composition can strip away lens coatings and may cause frames to become brittle over time. Always read your eyeglass manufacturer’s care guidelines before using these substances.
  • Paper Towels, Napkins, or Tissues with Lotion: These materials can be abrasive to your lenses and may leave lint or a film, causing streaks and reducing clarity.
  • Blowing on Lenses: While it might seem like a harmless quick fix, blowing on your lenses to fog them up for cleaning can transfer bacteria and saliva onto the surface.

Knowing what to avoid can save you not only from the inconvenience of blurry or scratched lenses but also from the financial burden of having to replace them before their time.

Special Considerations

Sometimes eyeglasses come with unique materials or special coatings that require extra care during the cleaning process:

  • Anti-Reflective Coatings: If your lenses have an anti-reflective coating, be sure to use only approved cleaners. Any ammonia or alcohol-based cleaners can degrade this delicate coating.
  • Scratch-Resistant Lenses: While these lenses are more robust than others, they are not entirely scratch-proof. They still need to be handled with care, using soft, lint-free materials for cleaning.
  • Sunglasses: Sunglasses often have different types of lenses and coatings designed for UV protection. Always read the manufacturer’s cleaning instructions to maintain their effectiveness.
  • Frequency of Cleaning: The more often you clean your glasses, the less time grime has to build up. However, more frequent cleaning also means more opportunities for scratching and wear, so always use the gentlest effective cleaning methods.
  • Proper Storage: When not in use, store your eyeglasses in a hard-shell case. This protects them from dust and reduces the need for frequent cleaning. Avoid leaving your glasses in the car or other areas with high temperatures as this can damage both the frame and lenses over time.

By considering these special aspects and tailoring your cleaning routine accordingly, you can maximize the life and effectiveness of your eyeglasses.


Keeping your eyeglasses clean is crucial for maintaining clear vision and ensuring the longevity of your eyewear. With these tips on what to use and what to avoid, you’re well-equipped to keep your glasses sparkling clean.
