Hello, new Prius owner here. The '04 I just bought has the typical old, hazy headlamp covers, and I'd like to get them looking as new as possible -- plus removing the haze helps the lights shine brighter, increasing safety and visibility. I read somewhere that baking soda (or basic baking soda toothpaste) clears this right up, super easy-peasey. So, I tried it, and some of the haze came off, but most of the haze is still there. Any other suggestions on cleaning/removing haze from headlamps? Should I take the covers off and clean the insides? What has worked for you? I don't want to spend $$$ if possible (otherwise, they'll probably just sit there as-is)
Honestly the "as seen on TV" item 'Wipe New' actually works really well. My grandfather had me try it and now I'm a believer! $10 at Walmart. give it a shot
There's a couple of Meguiars products on Amazon, I am using the lesser strength version as my fogging is mild.
Thanks both of you! Looks like with the toothpaste method, I didn't follow up very well, and certainly didn't wax it. I'll try that, and if it doesn't work, will try one of the other methods.
I got the kit that is sold at NAPA, which has various grit pads for an electric drill, and some rubbing compounds. Very good results.
I used 25% DEET anti-bug spray, and it made the lenses clear as new. I've heard WD-40 does the same thing, but have not tried it.
Various oily or waxy substances will fill in the surface erosion pits on the plastic and make things clear looking again, but only for a brief time based on how long it takes for evaporation or UV breakdown to occur. In a hot and sunny place that may quite brief. Actual sanding and polishing will be longer lasting as it gets down to a new plastic surface.
