Hi guys,

So I seem to have an issue with my rear window in the sense that when direct sunlight hits it, a certain portion of the window looks filthy.

Out of direct sunlight, the window look immaculately clean.

I have cleaned both sides of the glass vigorously, with different car window cleaners, to no avail.

Here are a couple of pictures of the 'dirty' portion in direct sunlight.





Any tips on how to 'clean' this? It bugs me whenever I'm driving and sunlight hits the back window, especially after I've spent ages cleaning the whole car. It kills the 'clean' look.

Thanks.

You might need to polish it with a mild abrasive. Something like this.

Any tips on cleaning/polishing the inside? It's a bitch to do.

Is it on the inside then? Most odd. Almost looks like finger smears in it. Have you tried something like an APC? What about a cloth with a bit of lighter fluid on it.

Kind of looks like someone in the back seat has used hairspray and that's over spray.

That or someone has done a terrible job cleaning up a a Marvin heh.

As for cleaning the inside, I seem to recall there is some sort of pad you can get with finger holes that lets you use pressure from the back of your hand which is more comfortable. Not sure what it's called though I'm afraid.

I am actually not sure whether it's on the inside or outside

I always use Meguairs Glass Cleaner and a micro-fibre cloth. It cleans the glass really well and doesn't leave any smearing. For the inside you can get a micro-fibre pad on about a foot handle in most pound shops. I find that gets around the bottom of the windscreen and rear window really well.

You're thinking of this

[Thermobaric]

Ah yeah. That's the one. Nice one.

Could it be adhesive residue when someone removed a tint film? If so you need a chemical to dissolve and get rid of it. Be careful you don't damage the heating filaments in the process.

If it's etching on the outer glass pane you need Cerium Oxide. You can get kits from here:

Looks like something to do with tints to me also.

Looks like laquer overspray to me, had this on one of my cars, scraped it off carefully with a blade and that was end of

You must be careful not to scratch glass and only do this outside not inside due to heater lines
