Removing scratches from windscreen - pullgees

I scraped off some bird muck on my windscreen and ended up leaving lots of fine scratches. Ordinarily I wouldn't be too bothered but these scratches are right in my line of vision so I need to get rid of them.

There are plenty of methods on youtube but mainly American and the products some are using are not sold here.

The scratches can't be felt with a finger nail. So best recommended way please.

Had a similar problem and got the tip to use toothpaste (it's a mild grinding paste after all) with a soft cloth and lots of effort. It worked for me, but it did take plenty of effort! Good luck.

Windolene is made for cleaning glass windows and has a mild abrasive in it.

Agree with the toothpaste, but also follow up with Autoglym car glass 'polish' (a cream - not the 'quick glass' liquid). The Autoglym polish is also mild abrasive.

Must say that I never fully removed the scratches I had (seagull poo that must have had sand in it) but you can improve matters. Might also be worth having a word with one of those glass repair outfits that often set up in supermarket car parks - they might 'fill' the scratch..

What the hell did you scrape it with. When I get bird droppings on the car (paint or glass) I simply put a piece of wet kitchen roll on for about 10 minutes and it wipes off without leaving a mark let alone a scratch.

I'm following this thread with interest: my windscreen has thousands of tiny blemishes which I'm convinced are trapping dirt and causing the wipers to drag across the screen.

But even a mild abrasive simply scratch the unblemished surface?

Jewelers rouge is the best I've found for this. Mix it to a paste and apply and polish with a dremel or similar rotary tool. Still takes a while, but can be done, I polished out some scratches on the aero screens on my vintage car that way.

Brasso should also work, but you'll be at it for hours as it's quite a bit less abrasive.

You can buy a windscreen scratch polishing kit from Frost Auto Restoration Techniques (F.A.R.T. !)

No idea how effective using this kit would be.

I've heard jewellers rouge just polishes the scratches so that the scratches are still there only they just look shiny and also gives a very very slight orange peel effect to the surrounding area in certain light.

Toothpaste has got two votes so far.

Halfords sell a kit for £29 but is that a very expensive tube of toothpaste with buffers?

I' m going to use a buffing machine when I decide on the best compound.

That's only part way through. You get a shiney looking scratch as a starter, then as you work, no scratch. You could get that effect with just about any adaquate abrasive if you stopped work early.

As I've said, I've done it. Only costs were the electricity for the dremel and the pot of elbow grease. I was given the Jeweler Rouge. Pretty cheap to buy though, a quick bit of Googling gave me £3.59 for 4oz powder and that will do a lot of polishing.

Thanks that's reassuring about the rouge. I was considering using an electric car polisher, borrowed one and found out that it vibrates like mad, so that's a no go. Next option to use a right angle chuck with a pad attached.

Me too, or blast it with water using the jet setting on the garden hose.

In my view many people take the view through their windscreens for granted,remember the last time you were driving into the sun and you could see the crap on the inside of the screen of the car you were following ! ( b***** fools )

During the autumn/winter and on any longer journey I always carry a wet chamios leather and screen cleaner, I wipe my screen down whenever I stop driving and weekly wipe over the wipers with tissue soaked in vinegar. It takes all of 30 seconds

That's far too sensible information for some posters on these forums. I treat my windscreen, inside and out with the greatest repect and hence attention. And don't ever use that technique of wetted newspaper either, as that will surely give at least some fine scratches and at worst more serious ones. This of course is often due to inadequate washing down of the glass first. If you don't do this, then there is the likelihood of picking up a piece of grit and then rubbing this all over your glass.

Solved! I eventually bought a kit which came with polishing pads, a 3" backing plate and a small bottle of cerium oxide in thick liguid form. Perservering for about 1.5 hours the scratches have gone. During this time there was a lot of stopping to check and to make sure the glass was not getting hot, spraying on water as the compound dried up

Although I already had some jewellers rouge I didn't have the right pads and no instructions and found I was working at too low speed on the drill and getting nowhere fast, 1500 -2000 rpm is recommended. So it was worth the £20 for the kit, bought online.

Ideally a polishing power tool is better - looks a bit like an angle grinder - than a drill but I couldn't hire a small one, only monster size on offer. Using a drill I attached a right angled chuck which wasn't up to the job and jammed up. So I had to resort to holding the drill vertical to the windscreen which made it hard work, but got there in the end.
