This is the same 07 Honda Accord from this thread were I was able to clean and save the interior...https://www.bobistheoilguy.com/forums/ubbthreads.php/topics/4837278/1
Another area that needed attention on the Accord was the headlights. All yellow, oxidized, hazed, etc... The car is too old, has too many miles, and is too rough to be replacing headlights. Just not worth the $$$. I have tried a lot of the kits out there in the past to restore headlights but any that are any good and/or that last more than a month require buffing, sanding, and even clear coating. Many are kind of pricey too at $15-$30+. No thanks.
A while ago I came up with this combo of products that works amazing and is cheap and about as easy as it comes. Unlike the thread above I remembered to take before and after photos so you can see it really does work. I kid you not in 2 minutes you are done with a light. This won't remove pitting or scratches but it removes the hazy, oxidized, yellow look and makes your headlights clear again. All for about $9 using products that can also be used elsewhere unlike the headlight kits. No muss. no fuss, no masking off headlights, etc...
So, I started out with headlights like this (yes the bumper cover is trashed - a snow plow sent a whole wall of snow up and over the car last winter cracking it all to heck and the previous owners didn't fix it - I will here shortly). You can't really tell from the photo but they were extremely yellow in addition to being all hazy and oxidized. You could barely see at night with the lights on they were so bad...BEFORE:
Step I - spray the headlight down good with LA's Totally Awesome All Purpose Cleaner ($1 at the Dollar Store). Mere seconds after spraying the headlights watch the yellowing begin to run off (it is grime and grease). Wipe clean with paper towels. Repeat until all tar, bugs, dirt, grease, etc... is gone. They will look hazy and cloudy but the yellowing should be gone along with anything else on them.http://www.lastotallyawesome.com/shop/all-purpose/awesome-all-purpose-concentrated-cleaner-24oz/
Step II - clean the headlights with glass cleaner (I use Sprayway foamy cleaner) to be sure they surface is nice and clean and no residue is left.
Step III - use Bluemagic Metal Polish Cream (yes you read that right metal polish cream - it isn't abrasive so don't worry) and apply like you would a wax or polishing compound. Use a clean paper towel with a small gob of it and wipe it all over the headlight lens. No need to rub super hard just wipe it on and keep wiping (I did circular motion like wax) until you feel it getting a little tacky then stop. Let it sit for about 30 seconds or so. Using a clean paper towel wipe it off and polish the headlight. Takes about the same effort/elbow grease as it does to wax the car. Once it was fully wiped off I used a soft piece of old t-shirt for a final polish.https://shop.advanceautoparts.com/p/blue-magic-products-metal-polish-cream-7-oz-400-06/7040003-P
That is it DONE! For a really bad headlight you may have to repeat the Bluemagic polish treatment for best results. Again, it won't remove pits and scratches but it makes the headlights clear again so you can see your headlights. The polish also leaves a silicone protective coating so it will last a while. You could use some good car wax over it if you want.
This is way easier than any of the headlight kits and it actually works and will last 6 months to a year+. IF they get bad again 2 minutes and they are once more good to go.
Hope this helps...AFTER:
