This is the only method that will actually have any lasting result. Keep in mind that you're polishing off all the UV coating (which is what keeps them turning yellow), so you will need to periodically coat the lights to keep them from turning yellow again.

I saw videos on the net using mosquito repellent. I haven't tried it, but I'm sure it is probably some solvent that is used in making the spray. Find out the ingredients then try to get the stuff.

no joke...
Bug spray with DEET

spray it on a paper towel and scrub it in good. Works quite well.

I learned it on a youtube vid.

And you have to do it every 3 weeks, right?

Mosquito spray, your welcome


Makes it worse after a few days and actually takes off a lot of the plastic. I wouldn't do it.

Rubbing compound or cleaner wax works well if you already have one of them sitting around. My headlights only cost like $40 a piece, so I'm doing that next time.

If you're talking about on the inside, just get new headlights

This. Takes 15 minutes a side. Less if you have a buffer to attach to the pads.

This is your answer. After you finish sanding make sure you put some sort of sealer on the headlights because you have now removed the factory UV coating. Dot use fricking toothpaste!

And the Sylvania (and 3M) kits come with everything you need. 3 different sandpapers, masking tape to protect the paint around the lens, a chemical to help the wetsanding go faster, and the final sealant that wipes on.

Did my wife's car about 4 months ago. Took 30 minutes, lenses looked brand new after and still look brand new.

OP, don't use any of the home remedy stuff. Get some #500 sandpaper and #1500, water bottle, and denatured alcohol. Use Renulite, although it is expensive it works and last for years. Spray down headlights, wipe off with clean rag. Spray down again and use 500 sandpaper and get the old coat off. Spray down again with water and use 1500 sandpaper, headlights will start looking white. Put denatured alcohol on clean rag and wipe headlights down. Car needs to be out of sun while doing this next part. Spray down headlights with Renulite after they have dried and wait for bubbles and lines to smooth out. May have to spray a few times. If cold outside run a blow dryer and heat up headlights, will help getting bubbles out. After its smoothed out placed car in sunlight for 5-10 minutes and you are done.

ETA: Will last you several years

ETA: When you get done with your car do you some friends cars and charge them 20-30 bucks until you finish the can.

Every answer is wrong.

Sams club will do your lights for $30 using professional equipment and warrant it against yellowing for 5 years.

Plus you can walk around and gorge on free samples during the 45 minutes it takes.

How much do you charge?

Eta and would you argue it's the process or employee doing it wrong who was at fault on your sams redos?

To be fair, 2 of the jobs was from one household, a mom and her daughter's car were done at Sams. They took daughter's car back after a few months and had them redone, a few months later they got hazy again. Honestly not sure what system they use. There wasn't scratches or anything around headlights like I've seen from Walmart who does it also.

I didn't realize Sams gave a 5 year warranty, mine is 3 years. Most people in headlight restoration business say its crazy to do more than 1 year since even OEM headlights start to get hazy on many vehicles after a few years.
