After washing the car, I notice that water remains inside the housing. If I drive the car prior to all the water drying, it starts dripping onto the side of the newly washed and dryed car. Is there a way to take care of this sans wrapping plastic bags around the sideview mirrors? Any advice would be greatly appreciated. TIA!

sucks up most of the water inside, but not all.

i tried compressed air, and it worked to some degree but some water was still getting trapped. now what i do is just take the car out for a short (1-2 minute) spin after drying off the car. this seems to shake out the remaining water from all of its little hiding places... i then just remove the remaining water droplets with a p21s towel. it's not perfect, but it's the best process i've figured out.

I use it in an enclosed garage. I keep the floor clean and avoid discharging the airstream on the ground. Works great on the mirrors, gas cap area, trunk lid drainage areas, license plate, wheels, etc. No more post wash drips.
