Headlights going yellow?

[Querentino_Spaghettino]

My car is approaching 8 yrs old and I noticed the headlights glass (or plastic I suppose), is going like a bleached yellowy color ? Is there any way of getting them back to clear or will I need to buy new ones? Any tips or suggestions please?

Yes, there are compounds to take the yellow off the plastic lenses.....Big C, Lotus, & auto supply shops should stock....

Some report that a brush & toothpaste works....

I had mine done at a car wash place that charged 300฿ to remove the yellow stain....Took them about 10-15 minutes by hand.....

Brush & toothpaste might not do the job. I've heard that they sand the lights first, and then polish it with some compound.

Just an example down below. Best is to give a professional IMHO

Probably the most painless way is to get it done in a Service Workshop. But be aware that unless a UV blocking coating is applied they go yellow again quickly. New units have that but it does also deteriorate.

Cut a lemon in half, add a heavy coat of baking soda to one half, scrub one of the lights for ~5 minutes.  Rinse.  Tough remaining spots can be tackled with a dish scrubber with toothpaste and baking soda.

You would be surprised how WD 40 removes and restores fading headlights.

 

Don't use a harsh cloth or the like.  Just spray it on and rub continuously.   Then repeat.

 

Or, as one member suggested, a local carwash/ local worksop could do it for a couple of hundred baht.
