Just when I thought I know all the applications of WD-40, I just learned another great application of the product. We have all seen the ads for removing the haze from headlight cover. You have to buy a big can and buff the haze away. There is a much simpler solution. Just spray some WD-40 on a paper towel and wipe the haze away. Yes, it's that simple!!! Try it and you will thank me for it.

A fcouple questions... does it permanently remove the haze, and does it damage the UV-resistant layer of the lens?

Im almost positive that the UV layer is on the inside of the headlights, gotta double check.

I guess i will be trying this tonight!

Someone be the guinea pig and post pics before I do mine , lol

^ haha agreed. I bought the restoration kit for my headlights but the results wasnt what i expected, hopefully this will do the trick.

if you guys only have a mild haze, you guys can always use toopaste (not gel), rinse, voila!

Im going to have to try these methods out tomorrow! Mine aren't bad but their not perfect either.

post results !! i wanna see it before i do it lol

WD40 is mostly a Solvent, I wouldn't really want to keep it on my plastics.

x2... for those of you having issues with your headlights hazing on the outside, there's a DIY i wrote with plenty of pics... search "RADRaze2KX DIY Headlight restoration"

Using wd-40 is just a quick fix and really doesnt do anything that the turtle wax ICE or the meguiars plastic restore is going to do. All of those i listed will just give the haze a wet look that makes it look clear when really it has not gotten all of the scratches and dirt and grime off. If you have a haze or yellowing you really need to use a restoration kit that has all of the sandpaper, buffing pads and ect this will be the only way to get rid of the scratches and film that cause the haze and yellowing

Incorrect sir. WD stands for Water Displacement. It's a light lubricant with many uses.

To the OP, this is not a good fix. It's purely temporary. You can do this same thing to privacy glass. Apply oil to the surface and you can then see through it. So on the car headlights, once you wash the car, it breaks down the WD and you're back to hazy lights.

Who cares what it stands for? Its primarily made up of Solvents. check out the MSDS(Material Safety Data Sheet).

I would not even call it a light lubricant, its a temp lubricant imo. If you leave it to lube anything important you will be SOL very quickly.

WD40 in a spray can is 45-50% Aliphatic Hydrocarbon which is a Solvent. The Next Major ingredient is LVP Aliphatic Hydrocarbon which is 12-18% of WD-40 and again its another solvent (Low odor paraffinic solvent or better known as Deodorized kerosene)

So we are now up to it being 57-68% made of Solvents.

The next thing which is listed as <25% "Petroleum Base Oil", Now we look into each of the CAS# there are four.

Distillates(petroleum), solvent-dewaxed heavy paraffinic(CAS No. 64742-65-0)
Distillates(petroleum), solvent-dewaxed light paraffinic(CAS No. 64742-56-9)
CAS Number:64742-53-6 Distillates(petroleum), hydrotreated light naphthenic
CAS Number:64742-58-1 Lubricating oils, (petroleum), hydrotreated spent

out of <25% only One item is actually a lubricating oil, the rest are solvents.


The rest of the ingredients only hold at most 15% out of the whole WD-40 spray, and they are not solvents.
