20214-12PK-12PK Plastic Cleaner and Polish - 156 fl. oz., (Pack of 12)

This is the best clear plastic cleaner that I have found so far. I have tried several other brands of clear plastic cleaner and this one beats those other hands down. I have even used Plexus to clean my plastic glasses lenses and it works great. It leaves a very fine slipery coating on my glasses to repel dirt and dust and helps with removing anything that does get on the lenses. The only drawback that I can find is the price. It is more pricey than the other cleaners I have tried.

This stuff works better than I expected. I use it on a polycarbonate windshield on my SxS and it has kept it relatively scratch free so far. I've washed the windshield when it's cool and out of the sun, then polished it with the Plexus and it looks like glass. Even when the sun shines on it, I can barely see any scratches and only if I look hard. Also seems to prevent or reduce static which helps to keep dust from clinging. Smells good, too. It's a bit expensive, but worth it if you have clear plastic that needs to stay clear.

I use this on a Road King windshield, works great, much better then glass cleaner. I was skeptical of the price, but decided to give it a try. I was pleasantly surprised how well it works.

Very difficult to find, however works well on golf cart windshield. Easy to apply, buff and wipe off. Can see a significant difference without scratching. Expensive but again, challenging to find

Worked like a charm on my old convertible rear window

This works very well for removing bugs and other road dirt from motorcycle windshields, fairings, helmet visors and the like. A little pricey.

I own a golf cart with a plexiglass windshield. I was told this product is AMAZING on keeping that windshield looking as clear as a bell. I've used many similar products designed for glass, and was reasonably skeptical that something could be THAT GOOD on plexiglass. I used this for the first time on a windshield that was becoming opaque from dirt, road dust, rain splashing, and lots more. Using a microfiber towel, I was extremely careful to take my time and use the product exactly as the directions stipulated. I can't tell you how incredible this stuff works. VERY EFFECTIVE. That plexiglass windshield looks positively medical-grade clear now. I think this product is a little expensive for me, personally, to buy lots of it, but I will make just one can of it last as long as I can because IT WORKS, and VERY WELL.

Works really well...but smells strong
