I've had this car from a few months and cleaned it inside and out.

I just went to check the wiper blade size, and as it's dark I needed a torch.

When I shone it at the windscreen, I saw this.

 

Now, these marks are on the inside of the windscreen. They are a pattern in the condensation on the inside of the car.

(I haven't driven the car for a week or so, and so I guess it's got a bit damp in there. I've already put a dehumidifier in the boot, and I've just added one on the transmission tunnel too.)

 

I haven't used a screen-mounted satnav in the car, though I used a sucker mount when I drove it home from original purchase, but certainly nothing directly in my field of view.

Besides, I cleaned the inside of the screen last week pretty well with a combination of 70% isopropyl alcohol and elbow grease.

 

My first thought was that the car has had its windscreen replaced, but as I said, these marks are on the inside of the screen, so that didn't seem to fit.

Anyone else noticed these on their car? Are they caused during the manufacture of the car?

 

They rub off easy enough, and I haven't noticed them before today or in normal driving. Only when I shone the torch on the windscreen.

I'm quite perplexed, TBH.

Thanks Roottoot! I had a search for rings, but that's exactly the thread I was looking for.

Searching for rings needs care like searching for squirters.

I once searched for Cognitive Behaviour Therapy using "CBT".

Oh I say!

This seems to fit the rings.
