I'd probably use acetone

That's a no no as well as lacquer thinner on the front windshield.It will affect the film in the middle of the windshield making everything wave looking.If it doesn't still come off with a blade,try barkeeper cleaner.It should come off with a metal blade.

Never had an issue. Your results may vary. We always used it in the body shop. Just do not get on paint, rubber or seals
 
The damage is not something you see on the glass,it's rather inside the glass.The way to detect damage is drive the car and your vision will be in layers of waves.acetone is safe to use on paint,but not single stage.and no seals or rubbers.as this mistake cost me 380.00 for a new windshield back in the 90's

Wait are you saying lacquer thinner will go THROUGH the outer glass layer and attack the inner film?

(let's assume the grass isn't cracked or chipped)
 
Are you talking about a windshield ceramic coating/Aquapel or something like RainX?

The inner film that holds the glass together if you were to get in a accident
 
Detailers Pro Glass Restorer followed by Wurth Clean Prep. I wanted to remove NanoSkins Rain Sealant to appy Black Label Glass coating and it worked out ok.
 
What would you use with the DP Glass Restorer? Hybrid white pad? I ask as I need to get water spots off my girls windshield.
 
Are we talking about a physical film which was applied (vaguely like a bra) or a sealant? Some responses seem to be applicable to one, the other to another.
 
I've had success in removing all remnants of Aquapel
using Naptha as the solvent to first "break its bonds"
with the auto-glass; followed by a thorough cleaning
of the auto-glass using a poultice of either Bon-Ami
or Barkeeper's Friend.

IMO:
Allowing the Naptha to have some dwell-time
will facilitate the removal process of Aquapel:
it's not really a wipe-on/wipe-off process.

If it is just a sealant, an abrasive polish is the way to go. Much like a paint sealant, there is little in the way of certainty when it comes to stripping with a chemical. In truth, the strength of bond for a typical glass sealant is significantly higher than with paint (meaning that it is harder to remove).
