| Water staining on door panels
Has anyone else noticed quite bad water staining on the interior plastic which lines the doors?
I noticed a small amount at first when having the doors open in the rain, but the other day I managed to soak the entire door whilst having the window open. Was leaving a car park and all the water from the roof came in through the window! Now any part pf the door that got wet had a nice light colour stain on it.
I know that this should clean off with the BMW interior cleaner that I got with the car, but does anyone have a way of stopping this staining in the irst place? Don't want to have to clean the doors every time it's raining.
The speaker surrounds seem to be quite bad for it also. |
