Have you ever tried to remove the yellow from plastic? Part 2 of 3 - An experiment!
Тәжірибелік нұсқаулар және стиль
This is a 3-part series on how I solve this. I’m always reminded my dad when problem solving - to look at things from a different perspective.
As a boy, science experiments fascinated me. I received an overhwelming number of suggestions from the test I ran a few days ago - how to restore plastic from yellow. A BIG THANK YOU! I think all of us are scientists - full of knowledge, ready to help the community (folks if you’re interested, read the comments below for suggestions).
I’m sure you’re wondering about the results of test. So, lets tune in...I was convienced one of these solutions could work. And it really didn’t take me a long time or a lot of money to setup.
Even though I let the hydrogen peroxide solution sit in the sun for a day in hot weather, it looked the same. I even ran this test twice, covering the container, but the yellow was deep set. A few folks suggested UV light or higher strength hydrogen peroxide in a very hot setting. I might have to try that down the road.
The vingear/water solution also looked similar. Again, I probably could have used a higher concentration.
The baking soda solution surprised me the most. It actually absorbed some of the yellow. I gave it a good scrub, but most of the yellow was still there.
In this shell game of life, it seems I might be out of luck for now. I tried a few other suggestions with no solid results. My dad was into chemistry and I remember every experiment became a lesson. He was also relatively frugal and relentless if he could save things. I have one more trick up my sleeve shy of just buying a new lantern. Time to ditch the lab coat and get to work. Stay tuned...
(p.s. I’m often reminded that Rome wasn’t built in a day. And I make a ton of mistakes. Upon reflection, many of my projects take some time, but I appreciate you sticking around if this kind of storytelling interests you.)

You needed hair bleach love
You have to get a certain concentrated peroxide, like those in hair salons that is far more than 3 %, and then it needs to be submerged in it, in a tub, under UV lights, sealed up. Seal it because UV lights can harm your eyes and prolonged exposure can hurt your skin. This is how a lot of electronics restorers fix old faded plastic casings.

That works exclusively on ABS plastic. This lampshade cannot be ABS, because ABS doesn't come out clear, it's milky and just barely translucent without additives. Heat and some sunlight is already effective. If peroxide developer is going to work, then 3% peroxide would already have a pretty substantial effect, peroxide developer is just quicker. I suggest that the plastic was likely PET, PC or PMMA which don't yellow by the same mechanism as ABS and don't restore this way. The yellowing is due to breakdown and there is no known way to fix it. The best course of action is making new lampshades. You can even copy the existing ones to retain their design with vacuum thermoforming or mould slosh casting.
The high percentage hydrogen peroxide paste used for hair bleaching is what I used to make my NES and old light switch covers like new. Give that a try!

Also, with hydrogen peroxide, the reason why it’s stored in a dark bottle like that is so it doesn’t oxidize. Once hydrogen peroxide is exposed to air, it just becomes water.
@evanjohnson8418
Жыл бұрын
The dark bottle is to block out light. The O-O single bond in hydrogen peroxide is not very stable, and light can give it enough energy to break apart, forming water and oxygen gas
See there’s frugality but then there’s your dad spending more money trying to fix the damn thing than it’s worth because he’s STUBBORN 😂

Try transmission fluid I've used it on yellowed headlights it's always worked for me. That or good old WD-40
The yellowing in plastic systems is usually caused by the plasticizers (additives to help melt viscosity and softness, which often contain aromatic rings) undergoing radical reactions caused by exposure to UV light over long periods of time. Not something that can easily be extracted with any aqueous wash.

I used a similar method to the water and baking soda to get yellowing off the bottom of shoes except I used hydrogen peroxide instead of water. There’s also a shampoo that would be used with a similar effect, I think it’s called salon40 or something like that.

Brasso works great, brings old plastic to like new condition, use it all the time when restoring cars, just need some elbow grease
Yep, unfortunately most kind of plastic yellowing cannot be repaired. Thanks for the video :)
Glass is best. I have run into the same problem. I’m in this home 20 years. I replaced the builders 4 lamps after 3 years (they were tinny brass and were starting to corrode). I replaced with aluminum (my old home had them, 14 years old still like new) and they lasted about 16 years, but paint was not real good. It was actually cheaper to buy new than spend the time to repaint. The entry light was in a covered entry area on the ceiling, this I painted and did not replace. I’m seeing that the new fixtures look ok after 2 years, but the paint isn’t as good as the previous. My old home, the fixtures are now over 32 years old, have been repainted white and are still there! The original paint was epoxy based, next time I will repaint with epoxy based black. Well life goes on, good luck. Jim
Baking soda is awesome to use indeed, will try this even on my car headlamps glass
I DID ENJOY YOUR PRESENTATION JUST THE SAME AT 70 👁 STILL ENJOY LEARNING (PERIOD)
Use "blending solvent" for autobody clear coat blending that's used to hide spot repairs, it will work!
Try volume 40 conditioner it works on shoe soles. Gotta wrap it in saran wrap and either put it out on the sun or uv light for 2 hours at a time it dries out so gotta do it a few times depending on how yellow the material is. But give it a try
off deep woods bug spray works like a dream for car headlights
Some plastics like older acryilic's can't have yellowing reversed, the only way is to replace, its a more commonly known thing on vintage watch repair for instance, in severe cases the acrylic breaking down off gasses a corrosive element and it begins to corrode delicate parts like the hands, face and movement parts, so best to replace or you will have a much more extensive repair down the line due to corrosion.
For the hydrogen peroxide you need to use a way higher concentration, you need the salon strength stuff and that works pretty well
The headlight restoration kit will most definitely work👍
You needed stronger H2O2. Like the kind from hair supply stores, Salon Care 40 Volume Devoloper. It's called RetroBrighting, and we in the retro computer field know it works to get rid of yellowing.
Clorox clean up spray. I don’t know what’s in it, but spray them. Let sit a few and then use micro rag. I just thought about using dishwasher soap. I would use to whiten & clear up.
This is like that one dude who tried to do all this for his clear phone case.
There’s a great product called Dip-It. It’s a stain remover and it works wonders. We use it in kitchens all the time to remove coffee stains from the insides of coffee carafes.
I’ve seen a restoration guy here on KZread that uses some solution and uses uv light and his old faded white plastics come out freakin amazing. The channel escapes me but I’m sure a smart guy like you can find him. I believe he restore very old tonka trucks and toys of that nature. 🤷🏽♂️
Cant wait for part 3
Could you try the paste used for cleaning the yellow and dirt off of car headlights? Wonder if that would work.
they sell these little kits at walmart or any auto store to clean headlights that yellow or get fogged and I used them as we have similar lights and had the same issue and it worked well.
Me aswell always loved to question it how does it do that then when you do science experiments it’s always satisfying to me to figure it out thanks for sharing ❣️🤗🫶🏼
A popular way to remove yellowing on plastic/clear outsoles of shoes is to brush them with salon care 40, put plastic wrap to prevent it from drying out, and then put it in the sun/in a box under uv light.
Great! You discovered crowd sourcing.
Bro was sleeping with the cap on 💀

I found my mom‘s 25-year-old bread machine in the back of a walk-in closet and the metal parts were still white, but the plastic lid had turned an ugly dark yellow so I went to Sally’s beauty supply and bought a bottle of hair bleach, the thick white pasty stuff and a cheap applicator brush. I painted the lid with a thick coating of that, put it in a clear big plastic bag and set it out in the Florida sun for several hours, brought it in and cleaned it off and it had whitened considerably so I repeated the process for two more days, letting it sit in the sun for about 6 to 8 hours a day and it worked. The lid was a slightly different shade of white than the metal body, I knew I wouldn’t get an exact match because obviously plastic and metal paint are going to age differently but it is hardly noticeable. I use it on the dough cycle when making bread now instead of my stand mixer.
retro computer restorers use a product called retrobrite (sp) to remove the yellowing of old computer cases, might work or maybe figure out what's actually in it.
Peroxide cream can work, but it's possible it can streak as well. A high % liquid is better option to prevent streaking. Tons of videos on it within the retro computer / console repair community
Hydrogen peroxide would work quite well if not so dilute. Try the peroxide hair cream. Cover in plastic so it doesn't dry. Works wonders on restoring the color on those old Nintendo systems.
This always works and you should definitely just melt the surface :)
I had seen something once about using aerosol hairspray on yellowing headlight covers.
Their is this one soap my shop teacher uses where we use to clean our headlights and works pretty good
Knowing how well Baking Soda & Vinegar mixed into a paste cleaned my mattress; I think I’d try that combo.
Use the same method as for yellow headlights... put acetone in an empty redbull can with a rubber tube at opening and seal tube around the opening ... then heat it w heat gun... Point fumes coming oit of tube onto the plastic... The heated fumes should restore the plastic... btw all the yellow should be wet sanded out... Also use safety precautions and PPE cause of flammables etc. Also spray a clear coat over it when done
i didn't knew electroboom Medhi would turn into a chemist.
one thing i didnt see in that bundle, while there was a headlight kit there, but there is another kind that is more like wax where you wipe it on, rub it in , let it sit a bit and wipe it off, blue diamond makes it and i think miguire makes it too, both work very well on headlights, headlights that were made in 1996 and had never been treated, just saying it might prove better results as the stuff had a chemical smell to it i didnt recognize amongst all the things ive tried before on the headlights trying to obtain similar results that might be the key to lifting the yellow out of the plastic and restoring the clarity

note it may take 2-3 times to obtain the clarity desired
On another channel I have seen a guy use something called "retro-bright" but he is applying it to the opaque plastic parts that computer cases are made out of. I have no idea what success you might have on clear plastics. But it might be worth looking into. It is a product that you submerge the object in and then leave in broad sunlight for several hours. So if might be like what you tried already.
OxiClean+UV lights will whiten yellowed white plastic, though I've never tried it with clear plastic. Might be worth a try, if you ever revisit the idea.
Right to the point love it
I dont know about light covers but this is usually for getting the yellow out of plastics that were in an environment where people smoked.
@buildtomade you also can use bug spray it works on car headlights aswell when they turn yellow like that
Use one of them kits for cleaning up head lights it works grate!!! And yes there is some sanding involved but you can use a power tool works grate tho I did it to my doorbell camera out front for the lense
Use something called Volume 40 cream from Sallys. Works great. The sun method works but it is slow and works better with a uv light. I use it to restore yellow game gear. I find 3% peroxide is not enough.
I remembered seeing them use a torch to put the gloss back into stadium seating. I'm wondering if a light blast from a heat gun might be able to clear it up.
I have an m&m display with yellowing on his shoes gloves and eyes so would love to see the next part
Uv with peroxide is probably the only way look up electronic restoration videos
Off deep woods with "deet"works on head car head lights.. might be worth a try .
A old lady at my job use to use The Smokers Denture cleaner tablets in warm water and let them sit in it over night
Should've tried scrubbing the baking soda light shade with some of the peroxide with half a lemon
I used suntan lotion and it worked good on my head lights a year ago and they look just fine.
Some kid at a gas station did my headlights for $10. I don't know what he used, but it was nontoxic (proved by him drinking it), and it worked great.
Bug repellent spray , it also works on headlights on vehicles. Spray and clean off with a cloth.
Him : Ever since I was a boy Me : he is sus
Order some “brite lites” from quality aerosols. Comes out like whipped cream and if anything will help it’s that. It’s the only thing that removes yellow from my cars headlights! Not many stores carry it either and it’s not well known but an old mechanic showed it to me and it’s my new favorite thing! Those are pretty severely yellow, good luck! 🍀

Use mother's mag and aluminum polish. Get it from walmart about 9 bucks for 10 ounces. Put paste on microfiber cloth and work in with two fingers with small circles. It should take about 3 minutes to polish into the polycarbonate. Then wipe with the clean portion of the cloth. Works great on car headlamps that do not have heat damage. Repeat after 6 months. It is really cheap.
do the baking soda rub but then spray a little lemon water all over it... would work best if you made the lemon water. boil water. add halved lemons. turn heat off and let sit overnight.

U can try Wet sanding it with fine sandpaper . Just like u restore headlights
The mix I know it works, although not sure if it does in this kind of material, it's baking soda mixed with vinegar no water
White vinegar and bicarb soda. Paste it on and give a little scrub with the green part of a sponge
The yellowing is oxidation, you can use a car polish or scratch "remover" to remove it, this also works on headlight assemblies.
I saw another short somewhere about removing the spaghetti red stain from tupperware, I think they did something with butter? Like rubbed it in then maybe microwaved it? I don't remember exactly but if you can find that short, maybe try that process on these?
