Hello, can someone please help. We have a Citroen cactus 2015. We noticed that there were A LOT of vertical scratches on the windows when we bought it so it went back 4 times now. They keep cleaning debris and polishing window to remove scratches, it’s fine for few openings/closings and then it scratches again. It’s really bad, sounds like hundreds of stones scratching against window. Does anyone have any idea what causes it. I really don’t want to go back to the dealer for the 5th time as they clearly don’t know what they’re doing.
