I pressure wash a lot of mobile homes in my area and im converting everything over to soft washing. Most of the mobile homes have a Florida room which is all windows wrapped around the front of them (most of you up north call them sun rooms). The windows are usually vinyl which is very soft/flexible or acrylic like a plexiglas, vinyl spots up very easily acrylic not so bad. I was wondering if anyone has had any experience with sh/ch on these types of windows...does it damage them or just spot up.
