Are you saying you drop the windows into the doors to clean rainwater from them? We all try it when we are in a hurry, but preferably in someone else's car because though insides of doors can be very wet places, introducing more water to them can lead to failure of the electric windows and doorlocks. The best way is a chamois left permanently damp in one of the waterproof door pockets. That cleans morning water off the windows very effectively.
