Mark on glass from dealer?
 
I bought a car a couple months back and the dealer had written a couple of words on the windscreen which I can see first thing in the morning when there is mist on the windscreen and when washing it and the screen very wet.

All other times its invisible and driving in the rain etc is just fine and not seen but how can I remove the pen marks?

Its been washed several times and I've used snowfoam/shampoo, Greenstar cleaner, Bar Keepers friend APC and AG Fast Glass but it still remains?

Any other tips to remove it?

I would try tardis next

Abrasive!

Had stickers on my back window from the previous owner, clay bar, tar remove, etc wouldn't remove it.

As above, something abrasive. Carpro ceriglass with the thin glass specific pad is very good but ive also used megs ultimate compound in the past with a normal pad and that worked too.

My new BMW had what appeared to be a PDI sticker on the rear side window that needed ceriglass to shift.

I think cerium oxide is a little extream in this case as the OP isn't trying to remove/polish the glass, as you've mentioned megs ultimate compound would be a good option with a foam pad

Carpro ceriglass is also advertised for removing hard water spots, road film and stubborn bird stains so could be a good shout for the OP.

I'd have initially suggested barkeepers friend which is abrasive but hes already tried it and it didn't work so needs something a bit stronger :thumb:

It's arguably the best product to deep clean glass, removes water spots, etching, staining and generally does what its designed to do in a safe efficient manner.
Also perfect prep before applying glass sealants as an aside.

cheers,

I wouldn't disagree, but most weekend detailers won't have Cerium oxide but are more likely to have a paint polish so instead of going out and buying the whole kit, glass polish, rayon pad, and the OP might not even have a polisher!

If it was me I would absolutely be using a paint polish as I don't have cerium oxide but I do have Lake county pads, a DA and many paint polishes.

However, I agree that Cerium oxide would be the best method but its not the only method and is not feasible for most

autoglym glass polish applied via a microfiber applicator and a bit of elbow greese sorted :thumb:

Cheers all. I have some older bottles of Megs Mirror Glaze polish compound being: Diamond Cut Compound 2.0 (heavy cut) and Speed Glaze (not as heavy cut).

Do you think these would work if i start with the least heavy cut one first?

You obviously didn't read the whole post and tried to turn this in to another 'i use this post'

The op has already tried what you suggested so not sorted! do you think I would have suggested DA otherwise

ash44 21-08-2019 09:36 PM

AG glass polish is not the same as AG FG . one is a spray liquid and the other is a polish . the polish will sort it with out using a DA

Heís trying to help by suggesting a useful product that the OP hasnít tried. Chill out buddy :driver:

SystemClenz 22-08-2019 09:23 AM

Another one for CarPro ceriglass, you don’t necessarily need a rayon pad, a small amount on a microfibre cloth will work on this type of problem.

Hope you get it sorted buddy and please update us with what worked :thumb:
