How To Clean Glasses


Cleaning glasses has recently taken on a new importance, since the arrival of the Covid-19 coronavirus. Research has shown that the virus can stay active on hard and shiny surface (like glasses frames) for up to 72 hours. Glasses are a good barrier for the virus, as it will stick to your glasses as well as your face. But cleaning your glasses has now become important in the fight against the spread of the virus. The CDC, the World Health Organization and others health authorities, have emphasized that both washing your hands and cleaning and disinfecting frequently touched surfaces daily are key in preventing Covid-19's spread.  However, you can ruin your glasses if you use the wrong disinfectant on them.

How To Clean Your Glasses

Cleaning glasses and their prescription lenses properly takes time and patience. The best way to scratch your glasses lenses is with improper cleaning. Take a few minutes to learn how to clean glasses, and you will not regret it. For example, the people that have chronically scratched lenses are the ones that clean their lenses the worst. Here is the best way to clean your lenses:

1) Disinfectant soap. Hold the frames under a faucet of warm water. Get your fingers soapy and GENTLY rub the lenses and the frame. This will remove Covid-19, and grease and dirt without scratching the lenses. Glasses cleaner will not disinfect your glasses as well as using disinfectant soap.

2) Gently Dab Dry. The biggest mistake people make when learning how to clean eyeglasses is to rub too hard. Rubbing hard, especially on a dry lens, is where most of the scratches come from. Gently dab the cloth on the lens until it is dry.

4) Use a Soft Tissue. Use toilet paper or a tissue (without any chemicals in it) . The best cloth to use is a microfiber cloth, followed by a clean cotton cloth, followed by a tissue or toilet paper, followed by paper towels, followed by sandpaper (just kidding). If your cloth is not soft, the lenses will scratch. If your cloth is not clean, the lenses will scratch. The best way to ruin lenses over time is to dry them with your shirt, a paper towel, or some other handy cloth.

Don't Use Harsh Disinfectants On Your Glasses

There are many disinfectants which are fine for use in your bathroom and kitchen, but are very harmful for glasses. Using these chemicals could remove the finish from the frames, and/or the coating from the lenses. Even if your glasses look OK after using these on them once, repeated use will certainly harm your glasses. Do NOT use any of these on your glasses:

Window or glass cleaner

Any kind of alcohol

Any kind of bleach


Lemon Juice

How to Clean Green Corrosion Off Metal Glasses

We hear from customers periodically about the green corrosion that sometimes appears on well-worn metal glasses. This occurs because facial skin acids can be quite corrosive, and they eat away at the varnish the covers all metal glasses, until the underlying base metal is exposed. This then reacts with the oxygen in the air and creates the green tarnish that is unsightly and very difficult to remove.

We at Eyeglasses.com cannot take credit for the following (edited) article, nor can we attest to its accuracy. But it sounds very accurate and it came from a devoted customer who seems to know his stuff!

"Dear Eyeglasses.com:

Thanks again for all your help with my problem of cleaning my gold metal glasses frames. All this time, I have been working off and on with this problem, mainly by joining NACE online, which is the National Association of Corrosion Engineers. The NACE members gave me various suggestions, which I kept trying. At one point, I even tried a homemade electrolysis experiment, but it just turned the corrosion black. Today, finally, I hit the jackpot. Please see my message to NACE below. I hope this research will help you to help others with this kind of glasses problem. I had just about given up, and then, success!

I tried many things, but nothing worked, so I decided to go back and read past posts some more, in particular the one from Rafael Suarez Baldo (Tuesday, February 14, 2012) with a reference to Preservapedia about using sodium carbonate, trisodium phosphate, and sodium silicate in an ultrasonic approach. Last week I tried a little Woolite in my new, little, cheapo ultrasonic machine, but the results were not impressive (ultrasonic should never be used on lenses.  If you want to clean the frame, the lenses must be removed first).

I thought I was just going to have to settle for the messy, time-consuming metal cleaner and pipe cleaners approach on my glasses, but this week I tried adding a little Natural Choices Oxy-Boost with sodium carbonate peroxyhydrate and Zep Pressure Washing Concentrate with sodium metasilicate. I ran the machine for one cycle and took a look, expecting the same usual disappointing results, but I looked again! The cable temples on my glasses seemed to gleam! I looked more closely--very closely! My glasses were gleaming, and I wasn't sure I could see any blue-green corrosion at all! Then I fished out my plastic temple covers from the ultrasonic machine, which I had put in just to see if it might do any good, and I couldn't see any blue-green corrosion on them, either! It even worked on the temple covers!

Thanks very much to all those NACE members who contributed ideas to solve my problem! I will send this good news to my optometrist, from where it hopefully may spread to all who are looking for a solution (no pun intended) to monel corrosion of metal glasses frames.
