I use it when my dog accidentally pees on my carpet/mat. It definitely helps clean and beats the pee smell. Would continue to use it.
What I don't like is it takes so long to settle into the carpet/mat. But I would rather leave it on the carpet/mat for 10mins knowing that it does its job.

We have an area rug that is in a high traffic area. I've tried many things to make this rug smell better but it didn't seem as if anything was working. The Gain high traffic carpet foam was great. The dirt it helped bring out of the carpet was astounding even though it's vacuumed several times a week. It also had a pleasant smell instead of a harsh chemical one.
