Hi , yes the marks were white , so would I just need to extra scrub the frames ?Hi Jesse Couldn’t see an image of the windows, but it might well be the Frames were extra dirty and then running onto the windows and leaving Mark’s or air vents, water dripping from them. If it was white marks on the glass it could well be the frames milking which is oxidisation and the frames will need a good rub to get rid of it. Hope this helps
To ensure this doesn’t happen
Thanks
