OdoBan 3-in-1 Concentration Carpet Cleaner Solution, Fragrance Free 1 gal., 4 pk.

I really loved this stuff! I have a puppy who is potty trained yet. She has been peeing all over the place and even though we clean up after her, the carpet was starting to smell. I tried using a different brand that I picked up at the grocery store. Although it seemed to clean the stains ok, you could still smell the odor. I found this on the Sam's Club website and thought I would give it a try. I hardly had to use any product at all! Be sure to use just a little bit...the first time I used it I used too much and I ended up with a ton of foam coming out of my machine! Once I got the proportions right, I ran the machine over the smelly carpet. It was like magic...the odor was COMPLETELY gone! I honestly did not expect that after going over the smell just one time. I figured for sure that I would have to clean it, let it dry then clean it again a couple more times. I highly recommend this product!
