hthomas02:we have one gray and one black, but to be honest, we only allow pretzels/goldfish/cheerios and water in the car. Finn has gone potty in the car seat twice, and those are the only times the covers have been washed. all of this to say, even the dark covers dont' look dirty but we're also crazy anal about what is allowed in.
This!! I do not allow milk or any beverage besides water in the car. We have a grey/black one and a pink flowered one and both look practically brand new (kids are 2 and 3.5)
