Removing paint from glass

Anyone have a good method for removing paint from glass? Besides a Razorblade.
I have a sheet of glass that has been professionally painted - so a razor blade won't touch it. I have used a mix of sulphuric acid and hydrogen peroxide in the past, which works amazingly well - but wondered if anyone has another method - using more readil;y available chemicals.

Already rang them before I bought this glass. Their quote was $500ish - this glass cost me $90 (brand new).

Fine grade steel wool works a treat. Used it all the time when detailing. Get it from ya local hardware

Cheers guys - will try the steel wool and the thinners. Don't know if thinners will work as this paint is very hard (seems baked on). Likewise - heat gun will not touch it (without getting it hot enough to burn the paint off...).

Paint stripper will work and shouldn't affect the glass and it's cheap, fast and easy

Thinners will do the job. A-grade thinners will eat through any paint you put it on.
Wouldnt steel wool scratch the glass?

Not if its very fine. I used this when I was detailing also...
Oh yeah - Use plenty of water with it too.

'A' grade thinners is the stuff to use no matter what paint and how old it is.
I would not use steel wool as no matter how fine it will scratch thick or fine scratches.
Obviously it will take a bit of work with A grade thinner not the general purpose stuff......
Also make sure you don't spill any on the paint as it will firstly soften it and when it dries it will be shinnier than the rest of the paint.....

If the glass is out of the car just use paint stripper. It will take 5 miutes. If it's 2 pack thinners wont have a hope of removing it.

Out of probably thousands of cars I detailed through the years I have never scratched any type of glass using fine steel wool. If you use it in conjunction with thinners you will definatley remove any paint that is on the glass

Just use some window cleaner and a razor blade if it on the outside (non-tinrted). U can use car polish on the glass too.

Definitely wouldn't use the steel wool myself, it'll scratch for sure.

Trust me it doesnt. You dont use the ole steelo pad from Coles. Get some fine grade steel wool from your hardware. I will eat my hat and my left nut if you can get it to scratch glass. I have cleaned hundreds of car windows with it

No idea what you have but i was looking at kitchen splash backs , they paint them , then bake them for a permanent finish. The company is called Deco Glaze , Phone 02 9624 7099 , maybe they can point you in the right direction , also acetone is stronger than thinners but don't do it indoors , might help , Cheers Paul.

Fair enough, I've definitely scratched glass with the el cheapo steel wool though.

This is the best thing to use, very easy and fast all the other ways will work if your removing overspray but this glass is painted you'll be there for 4000 years with steel wool and thinner

Thanks Paul, I think it is probably something along these lines. I will give them a call.

Yes - should have made it 100% clear - this is glass that has been painted/printed when manufactured - not overspray or anything like that.
I think it is only paint stripper or my old method (sulphuric and peroxide) that will even touch it.

I definently use paint stripper mate. Your wasting your time with the other products.
Steel wool will scratch certain glasses also and you usually only find out the hard way after it's to late.

We have had many of detailers get there asses kicked for using steel wool on customers cars and when you have to replace lexus windows it's understandeable at $1000 each minumum.
Cheers Mick.
