Paint on uPVC window Frame

[yj6aa]

I know this is a funny question, or whether its in the right forum (If not, I'm sorry!!) previous owners of my house have painted on the the window frame. Does anyone know how I can get it off?

I thought about a blade, but I dont wont to scratch the surface.
White spirit does not seem to touch it.

Any Ideas will be appreciated.

A lot of elbow grease !

A plastic blunt tools to loosen most of it or an old credit card with soapy water then polish it with upvc wax cleaner

Don't get paint stripper anywhere near it.
