I had a new windscreen fitted yesterday, it wasn't until I checked
later that I found the fitter had left grubby finger marks all the way
up and down the 'A' pillars. They are covered in the same stuff as
the headlining, a sort of cheap thin stretchy material. I've not had
much luck in the past with cleaning this type of material so just
wondered if anyone had any recommendations based on personal
experience.

Foaming car upholstery cleaner.

The brand I have use is Ambersil Groom and it works will.

If there's any risk that it is oily rather than just grubby I'd consider
having it done professionally and claiming from the installer.
