Very easy and worked really well removing most stains.
It seems that this odor eliminator has worked well on some cat urine accidents on my couch and carpet.
This product is fantastic. I have an older cat that won’t use the box unless it’s been freshly cleaned (there are two other cats in the house). He’s prone to spraying in places too. I spray Rocco and Roxie Stain and Odor and it neutralizes the odor right away. I highly recommend any pet parent have this on hand.
So far so good took old stain out of rug
