I use the powder it is slighty damp & when I sprinkle I use a large bristle to scrub the carpet brush they use to come with the package let dry for a few hours then vacuum noticeable difference,I have used their foam it works to.The smell isn't too bad but open windows or the door to help ventilate the smell.Not the easy clean system but on hands and knee's is my system to get down to the dirty spots to scrub
