I am hosting a poker party in my basement in 4 days. The stupid cat decided to spray a small area of our basement. The area is carpeted with no carpet padding. She has done this before and I had to bring in a carpet cleaning service to remove the smell. I rented a carpet cleaner from a hardware store. What would be the best product to be able to use in the carpet cleaner to remove the stain and odor quickly?
