Yes, WD-40 works to clean yellowed headlights. Yes, they will fog up again within 2 weeks. To prevent them from fogging back up, simply apply wax on your headlights. The same wax you would use to wax your car. That will protect them from fogging back up for at least 6 months to 1 year. Simply applying wax to your headlights every 5 months or so will prevent them from ever fogging back up again..
Ive for certain wet sanded headlights with a 280 paper and moved up through various finer paper until i got to 2500 then I had some pads of 3000 and 5000 with diamond grit in them. . . I like to use a bugsprayer with water and just keep it flowing so i dont clog up my sand paper or pads. Ive even used orbital both electric and air powered as well as the palm sanders a normal homeowner may own. Finished up before with charcoal lighter fluid and a rag . I prefer to buff then with a compound for either fine scratches on automotive paint or a buffing compound for clear plastics. Ive buffed with hair conditioner, used jewelers rouge and water, just seriously tried random handlotions...i prefer the stuff for the clear plastics or the fine auto paint scratches. Incidentally on a side note if theres real chrome and its needing brightened up or has some rust on it ,get ya a greeny pad and some good old gasoline and scrub away....it looks like new and dont gotta bother with all the crazy junk out there on the market. Im thinking to apply some suncreen as well. Lol
Been using on my 16 year old maxima headlights and it works not for months but for weeks without heavy rain even then you can reapply it week is good!!!
I wasted an unusual amount of the so-called cleaning/polishing kits. I finally ordered new headlights for somewhere around $85.00 shipped from Amazon Prime. I’ve been using prime for over 10 years and it pays for itself. But, the lights after 7 years still look new. Now I use all this polishing”stuff” for chrome, aluminum, steel, etc., projects around the house! Good luck to all!
I just restored the headlights on my sister's 2006 Buick with Maguiar's heavy duty kit. It worked really well. But you can use aluminum oxide sand paper in grits from 800 to 3000, wet sand progressively and then buff with a polishing wheel and then seal with a silicon spray. It'll cost about $10-$15, and amounts to the same thing. But you are going to need some elbow grease regardless. It took me about 40 minutes to do properly and was well worth it. I expect it will last for a good while.
For better result .... your final step better use 2K or Rust -o -leum glossy clear finish for UV protection, and it last much longer than buffing with polishing wax ! 3M also has a small package for headlight restoration for about $10-15.
This works for dirt and grime on the outside of the light but not the inside where it tends to get foggy too it also will not last if you don’t rinse and clean after the wd40
I just did mine with WD40 as my MOT is due in a couple of days time. But I have ordered the 3 M kit for later. As you said it's just a quick fix and that's the only reason I used it
Isn't wd40 great! All kinds of uses even making headlights temporarily looking good! Not bad at all. Lighten up people and quit taking life so serious! Peace!
@@nadamsga : It's a lie if someone claims it's a "fix" forever. If it is not said that this is a permanent repair, then it is not a lie. It is to some extent a fix (problem solving), but with the addition that only for a certain time. That's all. There is no lie in the WD40 effect itself. Only someone can be deceived in the duration of its effect. It solves the problem for 1 week. Just a little WD40 and 1 minute of application. That is enough for many people and they do not have to buy expensive new light.
WD40 acts as temporarily polish on plastic the shine actually gives the illusion that it's clearer and cleaner. This is an old trick to make old items appear newer and it better condition. It also temporarily hides small scratches. Also on the topic of the headlight kit I was out of buffing compound so I used hair conditioner so far a week in the headlights are still as bright as when I finished.
Try finger nail polish remover with cotton rounds it works I seen a video on it and tried it out you can see the yellow come off and stick to the cotton round it lasts for about two three months
Soapwater 1500 grade sandpaper clean and soapwater 2000 grade sandpaper 90 percent might need a few rounds then every 3 or 4 weeks just use tire shine after cleaning with soapwater or glass cleaner
Orange (citrus)-based cleaners are a virtually unknown miracle. Wipe it on fogged plastic - looks great for over a year. Duck (or any) tape residue - takes it right off! Almost any type of sticky residue that's hard to get off - takes it right off! This type of cleaner makes nearly ALL store cleaners (Fantastic, 409, etc.) look and act like you're using water! Problem is, they're hard to find!
Doesn’t fix but does help for quick fix it’s just the oil in wd40 basically, sand them and spray clearcoat for paint out of a rattlecan I found it protects longer but that’s me
Mixed feelings.. A 15 second spray job every 2 weeks doesn't seem like that big a deal... An alternative may have been a good idea, toothpaste, wax, rubbing/polishing compound etc.. takes longer but lasts longer as well..
So thing is, my headlights are obviously smoked. (Were, I have replaced them since this video). And, wd40 can make shitty headlights look ok for a short time. It’s not really a fix.
I use a lemon cut in half and bread soda on the end of a fork in the chuck of cordless drill on a low speed and rinse on dry of then use car polish and finally shine off both headlights,
It may become even worse with wd40 actually, because oil, such as wd40 may tend to stick to dust and dirt, making the headlights tend to get dirty easier
Baking soda, lemon juice, scrub, rinse, dry, add high temp clear coat. Lasts about 2yrs give or take depends on your climate and whether you park in the sun or shade.
My Glass Headlights never got cloudy......and my newer vehicle sits in the garage and still looks like new so I can't test anything........I do suspect WD-40 and 0000 Steel Wool might work okay but I would test a tiny spot first.
Thank you for the information, but you really didn't have to go there. I happen to be dating one of those pigs you mentioned. I spent an even $800 on a rig to hold her up vertical in a way that looks natural, with her tail tucked and the right heels, them pageants could be some good money coming our way.
Deet works best. It melts 5ge plastic. Don't wipe it after about 15 seconds, because it will be sticky until it dries. Once per year fix. Cover with clear polyurethane if you wish. Its MUCH HARDER Than the plastic. Your car paint and headlights were covered with it at the factory.
Wd 40 works the same as toothpaste for a short time but its cheaper then the head light clearner u buy to clean it fact its just like toothpaste or wd 40 after a few in comes back the only way to make it new is buy a new head light other then that just make it easy for your self spray on wipe off wd 40 or u can put toothpaste round and round on your head light then wipe it off yes lots of work ? Buy new or spay on wipe off
You have to be careful with the expensive ones, you speak of because you need a sealant to prevent the lens from fogging up again. Most have polishing wheels, or high number sand paper (1,000, 1500, 2000 grit sand paper) but without the sealant they're useless. (it's a U/V protectant)
It's about time someone ran a test on WD40 and found it worthless Long term! I personally found house old product that works just as well Basso wadding is a better than anything on the market at a fraction of the price! £2 pound one tin will last years, Cut a small piece of wadding clean lens first, Rubbing lens all over for 10minutes, Buff up with clean cloth job done!!👍
C leans them perfectly in less than 30 seconds spray on a regular paper towel. Wipe your headlight and bam its done then look at your paper towel will be all black
WD-40 just for temporary use, like you put some silicon spray or tire shine spray and once the layer of these chemical washed away by rain or sometime under the sun, they are gone and your headlights will show yellowish again ....
15 dolars kit gets u 6 months at best, and u get to work about an hour or two, wd40 costs 4 dolars, a small pack, for about 10-15 uses, lets say 10 ,that is 150 days, times 3 it is 450 days a year and a half for 12 dolars, i go with wd 40.
Spraying plastic engine parts with wd -40 will only last about a few days. The heat from the engine takes care of that plus dust and dirt doesn't help either.
I just keep WD-40 in the trunk with my jumper pack in my spare tire seriously it takes maybe less than a minute to do both headlights I'm good to go for a month
Or ...if the company had stop producing it may b its time to change the car ... 😂 Why hang on to things thats gonna make u cough out more dough n time replacing n maintaining it when its already time to say goodbye n move on. Cars are wear n tear item. 10-15 years is the suitable time to hang on to a car. Then its time to sell it off n get a new n latest one.
