I highly recommend Biokleen, Bac-Out, Stain and Odor Remover. Worked really well. Removed mild stains with little effort. The deeper stains required a little scrub, just a little more attention, but removed the stains. The smell is mild and didn't effect me at all, as I am sensitive to smells and products. When dried the carpet did not have any smell. I will buying again for sure.
