That said, in all my years owning MK7 and MK8 Golfs, I don't think I've ever felt it necessary to clean the inside of that little window!
Likewise, 12 years of mk7 & mk8 and never cleaned the triangles as they didn’t seem to need it, and I am a fusspot who likes to clean my car as often as I can (within reason), that’s why I had to search for the cleaning tips on here. That said I’m sure a google search of wider forums will throw up more tips similar to those you suggest Joe.
A point of note, maybe it’s down to dealer prep but despite picking it up during the warmest, driest summer in years locally, my 8.5 seems to have the most repeatedly smeary inside windows on any car I’ve owned in over a decade. I’ve cleaned them with a variety of automotive and household glass cleaners and the smears return quickly, even using brand new glass cloths. I’m wondering if the new dashboard gives off lots of fumes.
