Hi - I installed my dew wipes from stu a while back and found that lately I have scratches near to the rear of the door glass where there is a pad attached to the dew wipe.
Before I continue I will point out that there is No fault with stu's dew wipe as everybody on here who has bought from him know they are top notch.
It has been said on the forum on previous threads that the pads need a clean now and again to remove any dirt/dust.
what I found yesterday when I went to clean the pads up was - the bottom part of the door glass which doesn't get exposed above the dew wipe line had got totally grimed up over the years because you cant reach that area when you wash the car.
it is this area that comes into contact with the pads which is then transferred to the pads and the dirt gets built up then scratches the rest of the glass for you to see.
basically give the door glass a good clean before you fit your dew wipes - it is a little bit awkward to get to the lower part of the glass but worth doing.
just a heads up
