is there something i can buy to clean my wiper blades ? i clean them every time i do the car and i was wondering if there is something that puts moisture back in to the rubber while removing the dirt. i have used IPA (isoproponal) and cloths to try and clean the blades, and more and more black stuff just comes off and never seems to end.
i do use rainX on my windscreen but i have to use my wipers at slow speeds
