Windscreen cleaning

Since I bought my Z earlier this year I had thought the windscreen was all pitted with tiny chip marks. But I have realaised now that its actually little bits of hardened clear stuff which I think is tree sap as the roof was plastered in that when I first got it.

Can anybody recommend something good to clean this stuff off (it's rock hard) without damaging the glass ?
 
nope,

I didn't know what one was before I came on here either :oops:

a clay bar is something very sticky which is used to remove surface contaminants... can safely be used on glass too.

somebody help me here please!
 
Here you go, tested as well :D

With clay you usually use a detailer type spray to work on for some lubrication. Not sure if this would leave a waxy residue on the glass or not? I assume you've tried Windolene or similar first??

The one that came top in that test, only required water as a lubricant!
I have used it on my glass no problem
 
You can, if you're VERY careful use a scraper (the type that take a Stanley blade) to remove all sap etc. from the glass.

Like I say, I can't emphasise enough how careful you have to be and how gentle the pressure should be. You'll know it's working as when you move the blade back and forth it will leave a line of dust on the glass.

I've removed paint overspray from my glass using this method and it worked perfectly.
 
Thanks for the suggestions

Clay - seems to be a few different ideas on whether this is a good idea
Scraper - I tried this on my cooker top once (as advised in manual), and now I have a scratched cooker top. I know it's me who probably did it wrong but not wortht the risk.

Someone offline mentioned something called Autoglim Tar Remover. Anyone had experience of this ?

I wouldnt use tar remover on glass, what about using a glass cutting polish from Halfords and a glass polish to finish, although I personally would use the clay, always gets any tree sap off
 
Autoglym glass polish works quite well for a deep clean but doesnt do much for pitting; be careful not to get it near the plastic or rubber surround as it will be another job to get the white marks off.

A professional with a rotary tool and cutting compound might fare better?

+1, blue. I use ample amounts of water to lessen the friction while working the sap on the glass with a razor blade, at an angle. I've never damaged my glass, but I'm very careful and use a new blade for each bit of sap. It may go without saying, but don't try that technique on paint, rubber, or chrome- use a chemical specifically designed to remove the substance (road tar, sap, etc.) like Turle Wax Bug and Tar Remover. It takes much longer to do the job, but it doesn't damage the paint/chrome.
