Rear window cleaning

Post by ///M_aniac » Fri 23 Jun, 2006 19:57

Folks,

Cleaned my rear window this afternoon for the first time with the BMW rear window (tooth)paste.

Really does the job. Couple of applications outside then couple inside. Awkward on the inside but results defo worth it.

I've posted before about the BMW paste, It is a great product and seemed to last quite a long time before the window became cloudy again..
In fact I think I only ever did it twice in the two years of owning the Zed

Did mine recently with Renovo, much improved but it doesn't seem to last long, how about the BMW gear, does it last.

What I mean is does the plastic appear scratch free as Renovo greatly reduces appearence of scratches but they come back. In much the same way as wax will hide scratches on paintwork for a while.

Less of an issue in summer as roof down most of the time. My wife said she could see much better since I cleaned the rear screen, I said the roofs down there is no screen

Have just done it for first time there the other night, Kipper. Will report back in a few weeks. Remind me.

Garyw,

What's your experience been of its longevity?

Great news. Just stopped off last evening on way home - rear window looks superb after the treatment.

Thanks for the info Daneborough

I use the BMW toothpaste too. I've had my hardtop on for the winter months and the screen was quite cloudy. I did both the inside and outside twice and it really makes a big difference. Won't need to do it again until next summer.

One word of warning - make sure you clean the screen thoroughly before you polish it - otherwise you'll scratch it - it's very soft plastic.

It also helps if you're double-jointed :lol:. I still haven't quite got into the corners on the inside. Anyone got any tips on how to get those last irritating little bits?

Try and try again. you'll get a little bit further into the corners each time. Wrecks your arms though.

Auto Glym SRP is just as good - and you can use it on the rest of the car (except the hood :head: )
I've used both and would say the Auto Glym is possibly even better - it's certainly more readily available :wink:

It depends very much on your definition of expensive. I paid £8.80 for my BMW toothpaste back in 2001 and I'm still on the same tube. A little goes a very long way! That's about a pound a year!

I have always used this which did the job, then one I was polishing the car and just kept going with the Autoglym super resin which made it clearer than ever. Both products also work well on the headlamp covers as well :zmurf:

Does the AG Super Resin not smear? Do you put it on in a circular motion and is that on both sides? Sorry for the Spanish inquisition Mupps :wink:

No smearing for me and i do it inside and out . I apply using a Meguirs polishing pad(the wee yellow hand one) and buff off with a microfibre cloth... I think I use circular action..... I didn't expect the Spanish inquisition :zmurf:

I paid £3.51 for the toothpaste from the BMW dealer in Ipswich the other day... pretty cheap. I need to get rid of that fold mark in the window though!

AFAIK they have discontinued the toothpaste.
However, Autoglym SR polish is just as good

It is shown as part #4 below, part number 81.22.9.407.665, approx price £6-7. If price is shown it is usually orderable.

lycrake, is this what you bought?

If it is discontinued, then you will have to use another plastic polish - my concern with that is that using something else may cause the plastic to go brittle more quickly. Only time will tell I'm afraid.

Exactly my thoughts on using Autoglym Super Resin Polish and anything not made purely for plastic rear windows

Yep the tube of toothpaste is what I bought, I believe it was that cheap. I remember looking on here and people saying it was £8, and then remembering being pleasantly surprised at the dealers!

Think I remember buying from this guy over 12 months ago,

http://cgi.ebay.co.uk/MGF-MGTF-MG-MGB-S ... 5ad45c572a

The important thing is to buy the polish especially for this type of plastic as it's not just just the cleaning, getting rid of fine scratches etc but one that will make the plastic flexible and pliable if thats the right word. This stuff works really well and definitely helps when lowering the roof and makes the rear window much less likely to split due to going hard.

Just found this Renovo plastic window polish on eBay.
I've no idea if it's any good but thought the link may be useful for the non-toothpaste owning Auto Glym doubters :)
The seller also stocks Gummipflege.

Been using Renovo for years, it's good stuff. They also make hood cleaner and re-proofer among other products
