how to remove yellow headlight haze

I have read posts of people actually using fine grade sandpaper followed by polishing with different products to bring back the clarity. If they were real bad, I would purchase some new ones depending on how much $$$ they were or perhaps searching a salvage yard for some in better condition that might require less cleaning if any."I am ready to meet my Maker.

Pick up a bottle of PlastX and apply with a piece of terry cloth towel.
If you look carefully at this motorcycle windshield, you will see a spot that is clear while the rest of the windshield is hazy looking. I sanded this windshield down with #2000 grit wet-sanding paper and then polished a small area crystal clear using ScratchX and a piece of terry cloth for my applicator.
ScratchX works great for removing defects and restoring clarity.

~One man’s opinion / observations~
Application Methodology:
·Use a plastic polish Meguiar’s PlastX or Renovo Plastic Cleaner
·Plastic Cleaners can be used to clean and condition Perspex as well as flexible plastic but is not suitable for use on glass.
·Prior to application of a plastic polish ensure that the surface is clean and free from dust particles by washing with a soft cloth and warm water.
·It is not advisable to use cleaning detergents on plastic.
·Shake the bottle thoroughly. Plastic polish can be hand or machine applied
·Using a random orbital buffer with a 3.5-inch backing plate and a 4-inch (LC White) polishing pad or a terry cloth applicator
·Place a small dab (about ½-inch diameter) of plastic polish on the foam pad or applicator.
·Place the pad on the lens surface and turn on the machine (speed #4)
·Polish the lens repeatedly in a left-to-right and an up and down pattern.
·Continue polishing until all the polish is gone
·Wipe the lens with a damp Microfiber towel
·Inspect the lens, repeat the polishing process i2-3 times as necessary
Plastic polish will not remove clarity defects that are within the plastic but it will remove external/surface scratching and oxidation (yellowing)
I prefer to use a polishing method before turning to 'wet-sanding'
~Hope this helps~

Note the time I posted that, 6:04am,, I was in a hurry as I was heading out the door... I'm actually going to snag a better picture today that will better show the ability of this product.

Here's a pic of what PlastX can do. Of course your results may vary since some of the haze may be located on the inside of the light housing. This will limit your access to both sides of the lens.
Good luck! I think this pic is getting worn out, but the product works as advertised.

Hey,
Be REAL careful what plastic you sand!!! As I have mentioned in posts before, some factory headlights have a coating on them. This coating does not respond well to sanding!! Trust me on this one!! Do a test spot in a hidden area. If the plastic starts to turn white, and does not respond to polishing, do not sand the lenses. Instead, use PlastX and buff them thoroughly.
Just IMHO!

Hey,
The light looks great!!! If it had the coating, you would have found white blotchy spots as you wore through. I believe it is a UV film, that does look like clear coat. Sometimes, it can be polished back-off; other times, it can not. But if the lights were that bad, then any improvement is still an improvement!
