Just removed one of the kids car seat and found what appears to me a myriad of new life forms living underneath - no doubt the result of the collateral damage that occurs to foodstuffs when eaten by kids. A quick blast of Vanish and a scrub with a wet cloth has removed most of the offending mess but the material still has a stain that looks like the nippers have slaughtered a small animal in the back of the car. Anyone have good suggestions on how best to remove such a well entrenched stain?
