Home Made Lens Cleaner...




Introduction: Home Made Lens Cleaner...

About: I consider myself a professional student. I love learning new and challenging things, which is what brought me to instructables - lots of things to learn and do! I have Associates Degrees in both Fine Arts ...

I wear glasses, and cleaning them with the store bought lens cleaner can get spendy at $12 a bottle. (I tend to use it on other things as well...)

So after buying a bottle of it, I started making my own. It works just the same, if not better!

It also works great for cleaning mirrors, glass, lcd screens, tv screens pretty much anything you can get away with - and is made with items usually found in the home.

On with the show!

Step 1: ...What You Will Need...

What you will need is...

  • Water.
  • Isopropyl Alcohol 70%.
  • Spray Bottle. (I reuse the bottle from the store bought stuff.)

I use filtered water for my mix, in the picture is a Brita Filter Pitcher, it cost a few dollars more than a new bottle of lens cleaner and comes with a filter! (Plus, you can drink the water!)


Step 2: ...Mixing...

For mixing the solution, 

  • 60% Isopropyl Alcohol
  • 40% Water


This is far from rocket science, just add the ingredients into the spray bottle in roughly these amounts.

Step 3: ...Shake It Up!

Take your spray bottle, shake it up until you feel it's all mixed well and put it to work!

Until next time...

    Thanks, Mutantpoptart, the mix was easy and my eyeglass lenses haven't looked this good since I picked them up from the lenscrafters!

    STOP! Most lens cleaning products only have at MOST 10% isopropyl in a bottle... Zeiss for instance has 4-6% isopropyl in an 8oz solution. 96% is water! I would use no more than 10% isopropyl or risk injury to your eyes over time.

    Go! Sniff your professionally made eyeglass cleaner and you will notice it's mostly alcohol. And you're not putting this stuff in your eyes, are you?

    Excellent instructable that works. The key is NOT to use regular tap water because the smallest amount of minerals will leave streaks. Use distilled or filtered water. Right on.

    It's not so much cleaning the glasses, but whether the mixture will have any prolonged effect since some residue will be on the lenses and next to your eyes.

    Anyone knows whether isopropyl alcohol has any side-effects in proximity to your eyes?

    I am wondering if this recipe is safe to use on Progressive Transition Lenses with the no scratch coating on them? i am wondering because i have tried other cleaners and the cleaners made the no scratch coating get all spotted etc. and messed up my lenses.

    woody allen you know you don't have to worry about what things cost!!!just make soon yi do it!!!

    Yes you can - I wear transitions with the same coating and I've been using a similar mixture forever. I do however use less alcogol for my specs - so about a teaspoon in a 200ml bottle - and you can work it down for smaller quantities from there.

    good post -my cleaner 50% white vinegar 50% distilled water.and use a clean rag..

    not your handkerchief,

    what are the exact proportions?

    Would most definitely want to attempt to make this :-)

    Thats exactly almost how I do mine EXCEPT I live in the country on well water and my water is already filtered and instead of 60/40 I do 50/50 and it works BETTER THAN THE STORE BOUGHT 2 cents worth of alcohol and 0 cents for the water add a quarter for the bottle and u roughly have 27 cents in a 12 dollar bottle of eyeglass cleaner bet they use less alcohol too so really a ripoff to buy it from retailer go figure OHHHHHHHHHH it says right on the bottle under ingredients that it is alcohol and water NOTHING ELSE SO THEY BLANTLY RIP YOU OFF

    I didn't have a spray bottle, so I just poured alcohol straight from the bottle and wiped my glasses with a cleaning cloth. Worked perfectly. So happy to be free from the marketing trap of lens cleaners.

    You can use any coffee filter if you do not have a microfiber cloth for plastic lenses. I've been using them since 1979.

    I'm sure you can - the mixture here isn't exact or anything I would add a bit more water than alcohol in the case of the 91% though. I usually just eye the "percents" in whatever container I am mixing it in.

    Liquid soap is the last thing that you want to use on your glasses. Some glasses are made of special materials, or may have a UV coating. When they come into contact with soap they can form a film on the lens that will render them useless. As in "throw them away" useless. If you have old solid glass glasses, ignore this. This is specifically for the light plastic ones. Lens cleaner is specially formulated for use on glasses etc. Alternatively, normal window/glass cleaner is excellent. Would the formula work as well without the soap? If so, excellent! If not, check with your optometrist before using this

    I have had a pair of glasses with several coatings UV anti scratch and something else. I have cleaned them many times with soap, liquid or even the tablet type, I have yet to find any soap to cause a film on my glasses. I used the super expensive cleaner for about a month as they said the lenses would scrape easy, this is only a lie to sell more cleaner.  I soon found out the lenses where very resilient to scrapes as long as you rinse them under water before you clean them.

    I switched from glass lenses to the plastic type about 15 years ago and find the plastic lenses are way tougher than glass.

    I have to disagree about soap -- but the key is to use only the tiniest drop. Soap is a surfactant, which means it helps the cleaner spread all over the lens, which in turn helps the solution clean better. Granted, if you're scrubbing away you can clean anyway, however the soap offers another advantage: anti-fogging properties. If a thin layer of soap is left on the lens it breaks down the surface tension of all the little droplets of water which steam up your glasses. Instead of covering your glasses with tiny opaque droplets, the water spreads out into a thin, transparent film. In the picture I uploaded I cleaned only one lens with a cleaner similar to the one in this instructable (plus one drop of liquid soap). I then exposed the glasses to a humidifier: the untreated lens fogged up immediately, the other stayed clear. These are lightweight plastic lenses, I've been cleaning them with my solution for more than a year, and they are perfectly fine and undamaged... The key is to use a very small amount of soap.
