I have an original set of 69 tach lenses that have light scraches that I would like to remove so they look new. Has anyone had really good success removing light scratches from the lenses? If so what is your method? I tried polishing out the scratches with a pad of wet toilet paper and crest toothpaste, but it will take a long time to remove the scratches. Thanks Alan

On light scratches I've had good luck with a product called Flitz. It's a metal polishing paste but works well on plastic lenses. It is time consuming though.

One of those kits you can buy for dealing to weathered polycabonate headlights might work. you could try it out on another old lens. Ive also used Autosol petal polish on those headlights...a lot of elbow grease though.

I tried this multiple times on the dash lenses for my '69 Mach 1. Mine weren't scratched, but they were noticeably foggy. Once they were removed, you could see very distinct yellow spots, in the perfect outline of each gauge, where the sun had turned the plastic. I tried a 3M headlight buffing kit multiple times, and while it looked better, you could still see those yellow spots. I tried Meguiar's PlastX, which another forum member recommended. No change. I tried wet sanding with Meguiar's 1500 grit, which another forum member suggested. Nope, still looks clouded.

Keep in mind, your mileage may vary, this is just my experience. I feel like I wasted $30+ in materials and several hours of playing around, with nothing to show for it.

i used the mequiars headlight kit on my 93 escort and they turned out really nice. not new looking but 100 times better than they were.

just like you, i tried my best for the lenses for my gauges and couldn't remove the cloudy look either. mine weren't yellow though.

Good feedback, my lenses are only scratched, no discoloring. I'll try Meguires, if it doesn't take the scratches out completely, I'll buy a new lens set. Thanks
