Glass Glue? - How to remove

[One and a Half]

Hi all,
Have two cars with the same problem. Lexus UX250h/300h. The glass has by process of elimination an adhesive, and it's stubborn to remove. It is consistently vertical to the glass. The cars are shipped by sea and may have a protective film fitted on the glass, with the customer taken delivery, the dealer peels off the film and visibly you can't see anything, unless the glass is cleaned with a liquid. During washing, the film appears, but can dry off, so the window is optically transparent, well for normal driving anyway.

What has worked and it's a multi stage process which I want to reduce to maybe 2 chemicals, a remover and standard cleaner.
- Isopropyl (98%+)
- Acetone
- Isopropyl again
- Autoglym Glass Polish
- Meguiar's Glass Cleaner or Autoglym fast glass

Also tried: Turpentine, Orange Power goo remover.

Last night tried a citrus based degreaser, just laughed at it. I have ordered the 3M™ General Purpose Adhesive Cleaner, 08984 but it doesn't fly being highly flammable and is sent by sea container..... Am I on the right path or is it something different on the glass?

That would drive me nuts. I'm surprised the glass polish didn't give you better results.
Did you use a polisher or by hand?
Adhesive remover would definitely be in my arsenal for this, so yes you are on the right track.
If you haven't already ordered get Rapid Remover. Your brain cells will thank you for it

The 3M 08984 is my go-to for glue (and tar) removal. What does the Lexus parts dept. recommend?

I hate to bring this up, but in the old days Lexus used to apply a coating to the driver's window, I guess to sheet the water for better visibility. We used to talk about it a lot over on Autopia, back in the day. Are you sure that isn't what you are seeing?

A great thank you, there's a local dealer that has this chemical, so will try this for sure.

An idea, yes, after 2 years would have thought a coating would have long gone by now. If it were to improve visibility, when it rains, the streaks are there to see.

I wish there were better comms with the dealer's service department. A few emails on other matters are left unanswered, so my faith in them has dwindled to being close to a boycott.

It wasn't a coating like we would apply, it was applied at the glass factory. But that was a long time ago, it seems they don't do that anymore.
