I bought this for a bed bug problem. I used it repeatedly and did not solve my problem. An exterminator told me I had a very mild case so I opted to handle it myself. Not only did it not get rid of the bed bugs it would not even remove the soap scum in my shower door tracks until after I sprayed them with a cleaner and scrubbed it with a brush. Then I could steam it out. Worse hundred dollars I ever spent. Wish I had given it to the exterminator.
