Opps forgot to mention you can also use vinegar and baking soda and a small amount of detergent dish soap like dawn. It is pretty cheap to make up a bottle, gets every odor out, and even stains. I think the mixture is half a spray bottle full of vinegar, two teaspoons of baking soda, and one teaspoon of dish soap. It is a lot cheaper then getting petastic, but I like the ease of use that petastic give me. It's up to you though. God bless and good luck.
