Removing white oxidation from plastic eyeglasses
I have a beloved pair of eyeglasses I’ve worn for about 6 years now. I have a very narrow head and this pair measures 50-14-135. Finding adult frames with a narrow bridge and small lens size (but normal, adult ear positioning) is nigh impossible. Most “petite” frames still have as wide a bridge as larger sizes, which makes no sense to me. And children’s frames don’t have long enough arms.
But in the last year or so my rare unicorn frames have developed a hazy white film. It almost looks like they’re perpetually smudged with make-up. Various sources online claim that this discoloration is due to interactions with hair products, but I suspect this is a half-truth. The only area affected is the outside, on the front and on the part of the arms that see sunlight. Not where you’d expect hair products or make up to do damage.
Most plastic frames are cellulose acetate. While in itself this plastic is transparent to UV, in the presence of surface contaminants it can oxidize–growing pitted and, eventually, brittle. This oxidation is almost certainly the source of the cloudiness.
I’ve struggled to replace my frames. Three times now, I’ve bought a new pair only to decide they just don’t fit right. Meanwhile I assumed the white discoloration was permanent. I even vaguely wondered if I should try painting them.
I finally decided to do some digging online and I found several different remedies crop up. Some are chemical: renew your frames the same way you renew the plastic in a car, like with Armor All. Some are home remedies: toothpaste, peanut butter, lip balm, and baking soda have all featured. And some advise that the only way to really fix the problem is to gently scrape away the damaged surface layer.
I managed to restore my frames. The story is below, but here’s the punchline. The oxidized layer needs to be removed–it’s the only permanent fix. I recommend using a 4-way nail buffing block. Then, for additional shine, following up by massaging in a thin coating of Vaseline or lanolin.
Brush your glasses…with toothpaste
Well, it works on teeth after all.
My first attempt was the home remedy route. It was evening and toothpaste was something I had on-hand. The advice I found was to gently rub on and off the toothpaste, avoiding the lens. In principle, it works for the same reason it works on your teeth: the paste is mildly abrasive. The grit scratches off the oxide layer.
I followed up with baking soda, which I mixed into a paste with a little water. Again, abrasion is at work here. Then I washed with soapy water. The final result is below. Definitely an improvement, but still cloudy.
Buff to a shine
Next I broke out my nail buffer. I have a well-used 6-stage buffer. Stage 1 and 2 are grittier, for shaping nails, and 3-6 are for polishing the top. I used stage 3, the roughest polishing stage, to attack the oxidation. Even this level of grit feels soft to the touch. Whenever one of the actual gritty sides of the buffer would contact the frame, it would scratch, so if you try this, be careful! A gentle hand is key.
Because of the shape of my buffer, I could only really get the center well. The top and bottom ridges were tough to reach while avoiding the rougher parts of the buffer. And by time I got to the sides, the grit was basically worn away! I was pretty shocked, since I’d been using this buffer on my nails for months and months without it wearing so much as it did with the frame.
Shine on
As a final step, I took another home remedy piece of advice and rubbed in a thin coat of lanolin. It evened out the result and added some shine, as you can see below.
However, only two days later, I’m finding the parts I didn’t buff as well are looking hazy again. The center still looks nice. I’m going to pick up a new buffer and, in the meanwhile, I’ve shined them again with Vaseline. It gives a little more glossy finish than the lanolin. Hopefully it lasts a little longer.
If you give the buffing method a try, I recommend a 4-stage buffer, with sides that extend right to the edge in order to reach little corners and parts near the eye glass. I’ve read that melamine foam (such as Magic Erasers) also work well for buffing eyeglass frames.
If you give it a go, or have your own tricks for refreshing eyeglass frames, let me know in the comments!
Incidentally, I’ve just made my fourth frames purchase and I’m hoping this one is the charm. They are made of buffalo horn–no more cellulose acetate!–from the Cuthbert & Chen line by RetroSpecs. Although they are listed as 45-18, the bridge fit looks and feels more narrow. (How high they sit on your bridge plays a role in this.) They’ve also got my husband’s stamp of approval and he’s got something of a discerning eye.
Fingers crossed.

Just tried the melamine foam thing on my own glasses, where they had discoloured white in patches after getting something spilled on them… Worked perfectly! Back to glossy black frames again!
Excellent! Good to know that melamine foam does the trick!
Thanks for the info! You will amwant to regularly coat your horn frames in lanolin to keep them nice Mine lasted longer than my taste in that particular pair. 😊
Just curious if you could send your frame to an optician with a polisher, would you feel comfortable doing that?
Hi Jessica! If I had known that professionally polishing acetate frames was even a “thing” I would have done it in a heartbeat!
I asked my optometrist how much polishing cost. She mentioned it was around 200$. (facepalm)
Excellent post, I was going mad trying (and failing) to wash this stuff off my frames!
Btw, it’s a lot easier to do if you pop out the lenses and unscrew the arms.
Hello, is the usage of melamine foam( looks more like a hardcore scrubber to me) safe in between the eyeglasses – the part facing the nose. Because that part has oxidized a lot in my case and would like to see if it will work. Also is there any precautions if I must follow before using the melamine foam like wet the surface beforehand or something…?
Hi Ajay! I think the melamine foam should work just fine for you. You don’t need to wet the surface beforehand, but be careful not to scrape your lenses! If you want to take extra precautions, you could either pop the lenses out or cover them with an easy-peel tape, like painter’s tape. And please post your results for others’ benefit!
The foam works really well, but patience is definitely a requirement.
I managed to get oxidation off my black plastic frame, about 95% or more, by doing it often, say 5~7 times a day, for 2-3 minutes each session, over the course of a couple of days.
Progress with the foam is slow. I found that you can speed it up a bit by adding a bit of water to the frame say every 2nd or 3rd time you scrub. Be sure to dry off the excess water by shaking it off the frame.
Thank you for sharing your experience and tips!
I had this happen to me when I was dying my hair. I got brown dye on the glasses and removed it with nail polish remover. My tortoiseshell and purple frames had a white residue over them where I wiped off the dye that only disappeared when wet. I have managed to solve the problem for now with clear nail polish.
Did the clear nail polish peel?
I had the exact same experience as you – brown dye on the arms of the glasses that I tried to remove with nail polish remover, left a white residue that goes away when it’s wet. I came on here to see if anyone else has done this….and here you are! I’m going to try the clear nail polish idea but do let me know if it lasted or if you tried anything else.
Brilliant, Just wanted to say thank you. I tried the nail file / Vasoline method and the frames came out great.
I wanted to share something that worked for me on my dark frames. After trying several products, a few passes with a “magic eraser” got everything off. Your mileage may vary, but this was the only thing that made a visible difference on my frames.
Let me know if anybody knows what brand that is Magic eraser and who sells it.
Just wanted to say thank you for this post. My frame became discoloured after the summer (so I also suspect UV plays a big role). I tried just with a nail buffer (mine is 2-sided, so I used the coarser side, which is still very fine) and it worked perfectly! Luckily my frame kind of protrudes on top from the lenses so I could really go in without fear of scratching the lens. I don’t know if it’s a permanent solution, but for now I’m happy I don’t have to replace my fave, as I also struggle to find a suitable frame (small face, but large prescription / thick lens).
I just bought the Mr. Clean magic eraser and it worked beautifully and quickly.
Have a pair of vintage black Persols with quite a bit of white discoloration on the outside arms that I haven’t been able to remove. Found this blog, thought I’d give it a try but no lanolin so tried my Dr Martens Magic Balsam for leather in the black tin which contains lanolin and other waxes/oils. Applied a small amount of balsam lightly smeared on with the sponge applicator from the product, rubbed it in with fingers. Rubbed with soft cloth to remove excess. All white residue 100% gone. Deep black sheen restored.
So I read with interest. My wife asked me to sort this out for her a couple of years back I chose a small polishing head on a dremil. Bad idea this started to polish its way through the plastic which i had to delicately try to balance out. I didnt do a bad job in the end and it gave her 12 mths before she needed some new ones. Anyways your experience got me thinking about sorting my own. I went for a pound land magic sponge followed by a delicate application of boiled linseed oil. This worked a treat without to much bother. The boiled linseed oil came from a tip someone gave me for refurbing plastic car bumpers. Thanks for the inspiration.
I have used Perl by CarPro with sucess
There are some steps to remove sweat stains from glasses. Step 1: Wash your glasses. Step 2: Clean with lotion dish soap. Step 3: Use the magic eraser. Hope my way can help someone.
I have a very expensive pair of Cartier, no help at all from vision express or even Cartier, they just wanted to sell me new arms for £300 plus, however I’ve found that after easing them with shower gel I thnn rub the arms with olive oil this makes the arms look dark and like new and last about 3 days, then just repeat
I just used a Mr. Clean Magic eraser to remedy this on a pair of plastic black frames I have. Super fast, maybe 2-3 minutes of gentle rubbing (avoiding lenses). Then coated with a drop of jojoba oil. They look so much better.
Thanks for sharing!
It really works! 😃
I’ve been looking for an option to rejuvenate my acetate frames. I had just decided I’d have to Thank you! I have a pair of gold glitter Gucci frames that I can’t part with, and I’m not a ‘glitter’ or ‘Gucci’ or flashy person. I am constantly getting people asking me where I got them, but they’re a few years old and were a limited color even then. I’ve been searching online for a replacement for a year throughout the WORLD! I had finally come to the conclusion week that I’d have to just accept that I was going to find another type of frames, but I found your post instead. I’m actually going to the store now to get a magic eraser, and a few other things people suggested. Then making an appointment for new lenses. You made my WEEK!!!!! 😃😃😃😃😃
