Any advice on this?

I have got some very fine 'grit' stuck to the inside of my car windows (the Z3). You can't see it but it feels rough to the touch. I think it may be fine, hot grinding dust.
I can't find anything to remove it. Any ideas without scratching the glass?

I was going to try a bit of t-cut or metal polish but am scared it may scratch. :?

What about clay? You can use it on glass as well as paintwork.
 
Have you tried a razor blade like this and trying to cut it out.

Sorry to report this happened to a friends car, contractor grinding near it and needed a new windscreen. Oddly the particles that came into contact with the paint work just dusted off without leaving a mark.
 
I’ve recently discovered Bilt Hamber Surfex, which is worth a try on anything. Next I’d definitely try a clay bar. I’d also have a go with my Festool paint nibber, but it’s only really suitable for a flat surface.

It’ll be melting into glass most likely. You might not be able to get rid of it.

I don't think it has, as I can (sort of) scrape the particles away with a fingernail. Odd thing is they are completely invisible when looking through the glass; i.e no colouration of the 'grit' at all.

I could post a picture but it would just show a clear sheet of window glass. :lol:

I'm going to have a go with some t-cut, gently in a corner, as I don't have such extravagances as clay bars or posh cleaning equipment. :oops:

Generally glass is pretty hard, it's sure difficult to polish. If it comes off with a fingernail I'd second just using a razor (you can get plastic ones).
 
Problem is the glass isn't flat; it's got a very slight curve to it. I don't want to scratch it with the edges of a flat blade.

This building cars lark is a PITA. One step forward, three back. :x
 
Have you tried a USED plastic wire pad, the sort used for cleaning pans? Use it gently with soapy water. I use it to clean black polished granite and it’s okay. But be gentle.
 
Trollull stove glass cleaning pads
made of double layer steel wool but wont scratch glass.
we use them at work on the stove glass.
 
I would suggest a clay bar as above, it wont have a problem with marring so you can really go to town with it and it will of course have no problem with the curved surface. Obviously once done throw it away you dont want to be using it again on your paintwork at some point in the future.

Other option is an IronX type product as a way to loosen and dislodge it for easier removal, although just cover the interior of the car you dont want that stuff stinking it out forever.
 
I’d work up towards the most aggressive solutions, so I’d start with an iron-X type of product as mentioned by coldel. You want to get as much off as possible before you start scraping.

I'd go directly to plan B and B is for Ball Peen Hammer and a bit of excess. :evil:

Thanks. I went with that option and problem has been solved. It has brought up another problem, though. :oops:
