Lay the bra flat on the ground (I spray the driveway with water first to clear it). Use a bucket of soapy water (I use the car soap). Then use a big bristle brush and scrub both sides. Rinse and let hang to dry. I do this everytime I'm done using it. Don't let it dry in the sun. Believe me, after using the bra in snow conditions where its icy and muddy, that thing is totally wasted. There's all kinds of crap stuck to both sides. But after a thorough cleaning, its ready to use again...<p>P2<br>98.5 2.8QMS
