Headlight lenses are that milky/yellow color primarily because of the UV rays from the sunlight on the poly-carbonate lenses.

Windex now has an ammonia free product; Windex Crystal Rain, safe for plastics.

I gotta tell you, when I fogged up my skylight, I was using Windex, which clearly was labeled as ammonia free. However, I have been known to take a near empty bottle and pour its contents into a new bottle when it starts pulling air. It is possible I had some ammonia in the new bottle. But, now, Lexan only gets soap and water, like the skylight manufacturer states!

The headlight condition described above is crazing, not yellowing.

Mayonnaise will restore those faded headlights to like new looking. Put a little on a terry cloth towel and simply wipe the lens. You will have to reapply it after about 4 car washes. It also does miraculous things to faded gel coat on boats or other fiberglass materials. Again it will have to be reapplied every so often but it is much easier and gives as good or better results than waxing.

Consumer Reports ...without any evidence of research... states the following in that report:
"Ultraviolet radiation from the sun is the primary culprit in the headlight aging process, compounded by other environmental factors. The problem tends to be most serious in warmer, sunny climates, but we've seen plenty of evidence of it in northern regions, including on employee cars in our own Yonkers, N.Y., parking lot."
In other words...they are pretty good at contradicting their own imaginative causes of headlight lens problems. In fact, they are GUESSING because they simply haven't tested their theory that sunlight is the problem.
Even worse.... Consumer Reports FAILS TO MENTION that ammonia will ruin plastic lenses when they recommend owner-actions: "Get in the habit of regularly cleaning your lenses with a household glass cleaner."
Many car-washes use ammonia-based window cleaners and they apply them liberally to all windows/lenses. Many owners unknowingly do the same. Over the last 20 years, I have owned four cars with plastic headlight lenses in sunny Texas and NONE of them have been garaged and NONE of them suffered damaged headlight lenses. I do not allow car wash personnel to clean my headlight lenses.... EVER. (in fact, I rarely allow them to wash my car since I live/work way out in the countryside...It's more convenient to do it myself.)

Mayonnaise is largely vegetable oil. If you don't plan to eat your car... you might just use a bit of vegetable oil on your lenses if you choose to follow that route.
