If I can put it in the washer, I use the same soap I use on my husband's hunting clothes to take the scent away. It has worked well so far. I think I have only had to rewash things one time and I figure that may have been fabric content.
My female cat got caught in the laundry room one time and she peed on a pile of laundry on the floor now she wants to pee in that spot all the time so I have to keep the door closed.
