Hello to evrryone. I need to shampoo my carpets because they are Grey and getting dirtier and have some darker stains. I have 2 small house dogs and 2 cats and of course two daughters that like to sneak drinks/food on the carpet areas so that doesn't help to much in keeping them clean either. Anyway, I have a fairly new Bissel carpet cleaner and want to know what is a good product out there detergent wise that will clean my carpets really well and remove stubborn stains and also do they sale a carpet anti stain or carpet protector to put back on the carpet once it is cleaned up. We have cleaned the carpets a few times in the past and I think the anti carpet protection has been removed also. So I am getting your opinions on carpet cleaning. Thanks, Bob
