Looking for a cleaner for back plastic window
 

I was browsing for a cleaner for my back plastic window, and look what I found.
Plexus Plastic Cleaner for Automotive Uses

If you have a haze or small scratches the best product I have used is Novus NOVUS Plastic Polish

My back plastic was almost unusable until the dealer had a detailed come in and work on window. He used this and it turned out great. It of course isn't new but close. He only spent about an hour on it and I will work a little on it this spring. The edges are still showing signs of age but just a quick look no one would notice.

That's what many of us have used for years. Great product.

Oh man... MEGUIARS PLASTX. $10 a btl or something. Came crystal clear and soft as NEW.

I've used a "soft" foam polishing pad on a rotary and ran this at 2k RPM for a good 5 min. Wiped out, cleaned, and just couldn't believe it.

The real blast was after I've done the same routine, but from the inside of the car i.e 2k spins for 3-5 min (prep for back aches my man!). Its only then that I've noticed that this product was simply meant for the Boxster rear foggy window (you do get lucky with silly produccts sometimes!). The windows came up literally brand new and all the small scratches vanished.

Note that my window's temp came up pretty hot after a few minutes of buffing at 2k (summer day). Not sure if this was a major factor to success but anyway, I'm convinced it did. I've left the roof down overnight for the window to relax while temp cooling down and all the stretch came back normal the next morning.

From only two meter away, you wouldn't make the difference between my window and a new one.

Luck with yours there

Oh and do your headlights for twice the buffing time (10-12min) and you'll be in for a serious laugh buddy. Works as advertised

plexis is good stuff. it is what i use to keep my rear plastic window clean

Don't bother with anything but this choice, if you are not buying plexus just use pledge, every good boater knows pledge is killer on plasti glass.

plexus, My neighbor gave me a can. He uses it on his airplane's windshields and windows. SWEARS BY IT !!! and it smells, good !!! I trust him.

Ditto on both Novus and Plexus. Use the Novus system to get the yellow and bad scratches/oxidation out, then wipe down w/ every car wash with Plexus. Same process for the headlights and tail lights.
Many Harley-Davidson shops carry both products. Boat shops are also a good source.

Another vote for Plexus, great product. Not a scratch solution, but a great cleaner. Make sure to use a non abrasive cloth.
