Now to get rain x or water repellent off windscreen, desperate

[Naughtynovembertree]

I treated myself to a brilliant car wash but driving away the window smeared up terribly and my water and wipers couidnt shift it. I had to pull over with engine running and heater on until it was dry.
I can't believe it.
The whole idea was to get brilliant clear windows and I think he sprayed it on the inside as well 😭.
It's something like a rain x water repellent, does anyone know how I can get it off.

What did they say when you went back to them?

I didn't because it's friends family.

Have you tried soapy water? Obvs rinsing well afterwards.

Strange, but true WD40 gets sticky stuff off glass. It might work on yours, but I’d try a small patch first.

There's a product call rain X rain repellent, you can get it on Amazon or Halfords (and probably other places)

Sorry, I should of read your whole post properly!
