I just washed a TFP cover yesterday. Actually, I ran it through the washer twice because it was so dirty. It was the cover off my friend's seat that she has for her daughter. I helped her turn seats around yesterday and saw how dirty the cover was so I just put my extra cover on her seat and washed hers so Nour would have something to sit in yesterday. Anyway, the cover looks fine. I've had no problems after washing them. I put it on the delicate cycle, wash it by itself and drape it over our shower rod in the bathroom to dry. After seeing her cover, it's exactly why I only allow the kids to drink water in the car!
