How do you clean a dirty headlight lens?
------------- i have the plastic light lenses on my car they
were all foggy and yellowish i put a small buffer pad on a drill
applied sone mild polishing compound on it and buffed away then did
it with wax they came out like brand new it was very easy
Cleaning a dirty headlight lens requires a product or products
and techniques suited to the material the lens is made of and the
kind of "dirt" on the lens. Let's look.
Generally the problem is oxidation, If uninhibited it will form
naturally on acrylics exposed to heat and moisture creating a thin
veil over the lens that gets thicker over time. There are two ways
to address oxidation.
There is the easy way:
1. Use a acrylic lens deoxidizer,
I recommend Pittman Original ALR. its a non abrasive DIY
solution that takes seconds
Or you could do it the hard way
2. Use a polish , which is abrasive which I don't advise
for oxidation removal on acrylic or plastic.
First you need to have a better understanding about headlight
construction before you start.
A lens could be made of glass. In this case, just about any
glass cleaner would work. (Avoid abrasives; they could scratch the
glass.) If road tar or tree sap is the problem, a solvent will be
needed, and car parts places as well as good hardware stores have
what you need.
In the case of a plastic lens, cleaning is accomplished with
glass or plastic cleaner in a manner similar to what is used on a
glass lens. If road tar or other gunk that is not water soluble
ends up on the lens, a solvent is called for. Be sure to get one
that won't attack the plastic. (Try a tiny amount in a lower corner
before applying it wholesale.) Lastly, a plastic lens can oxidize
where a glass lens will not. Often we see a plastic lens take on a
"white-ish" or possibly a "frosted" look. In this case, the surface
layer of the plastic will have to be removed, and it will have to
be "polished off" by some means.
The reconditioning of a plastic auto headlight lens is probably
best left to professionals who have equipment as well as the
appropriate polishing compound (s). But if you are a hard core
do-it-yourselfer, start researching the materials and equipment
you'll need to do the job. There are kits out there you might try,
too. Do your homework, and begin at an auto parts place, hit some
body shops, and particularly some big auto detail shops. Certainly
the web can help.
