I was so stupid. I went googling and youtube to try polishing my vinyl rear window..

I tried rubbing with toothpaste and then using abrasive sponge to polish. And now it is fogged up.

Stupid me! Anyone with similar encounters? Anythint i can do now?

I looked at the vinyl from an angle.. seems like the fogging is from micro scratches..

Ive ordered a bottle of meguiar plastx.. anyone has any opinions about this other than im so stupid?

I've had good luck removing scratches in the rear vinyl window with Blue Magic headlight lens restorer.

perspectivism · 10-05-2016, 02:39 AM

From the look of mine do you think it is remotely possible to remove the dense hazing?

The Novus products are pretty much the gold standard for plastic window treatment.

jcslocum · 10-05-2016, 03:22 AM

Just use plastic window polish and work hard at it.

I have also used headlight restore polishing compound to remove fold rub scratches out, doing it by hand

You would have to have someone sew in the new plastic window if you purchase it. That won't be ideal, as they'd have to cut a little bit of the black cloth off to sew in the new plastic. Just try to polish the haze off by buying a plastic polishing cream like the guys here suggested. Don't use an abrasive sponge to wipe off the polish cream. Use a soft cloth or microfiber cloth.

Thanks for the replies. Replacing the top here in my country is a 2 to 3k usd job.

I was stupid to use an abrasive sponge and tooth paste.

Anyone had it as bad as me? Possible to polish the vinyl window until it is less hazy again?

Try and use Plex over and over again in small amounts by hand. Do not use a machine as that will eat away at the plastic and the heat friction will cause even more damage. Soft cloth and doing it daily should do the trick... sadly there is no 'fast' method of recovery at this point.

Sorry for your troubles, but 9 of out 10 dentist will tell you not to use Crest to polish your plastic window. Are you by chance a dentist?

I'm guessing it was more the abrasive sponge.

Mine had a bad hazed up area in the middle from the latch rubbing on it. It took a lot of elbow grease but it cleaned up decently. It is a slowwwwww process and you have a much larger area, but it is doable.

Thanks for this. Its quite reassuring. Do you use fingers to rub it in or sponge/microfibre?

Its a fatal combination of toothpaste, abrasive sponge and plain stupidity on my part

You aren't the first person to do this, so stop saying you are stupid! If you made the same mistake again, then you might be stupid.

Once your window goes hazy and then yellow the plastic is on its way out.

It wont be long before you start getting cracks, maybe a couple years if your lucky and don't retract the roof at all.

Better to invest your time in getting a new plastic window sewn in ($150-$600), buy a new third party replacement top ($450-$700) or replace the entire roof with a used glass window 03-04 4 bow top($700-$1200)

I suppose polishing will get it useable at least for the short term. I have heard others say that the plastic lens polishing/restore kits work reasonably well.

Tip: Never fill oil into the coolant system. Never fill Water into the Oil system. So your boo boo is not too terrible compared to some others unfortunate mistakes.

Novus 1, 2 and 3 They sell a kit with bottles of all three.

Kept mine clean and supple for 7 years. First treatment, With a clean cloth. Use the abrasive once, then the middle and finally the polish. Use on the inside of the window too but just the mid and polish. To maintain just the polish every 3-4 months.

Once it is clean, use soft felt between the folds when the top is down so the plastic doesn't rub against itself and use any grit like sand paper.

Hi, I used Mothers Plastic Polish on my MG for several years, worked a treat.
