After watching the impressive informercial for the Scunci Steamer on tv, I ran right out to Bed, Bath, and Beyond and bought one. Brought it home and tried to start cleaning. IT DID NOTHING!!!!!!!!! It didn't clean my oven, grout, shower doors, sinks, etc. The dirt stays caked on, it does NOT turn into a liquid as in the infomercial, which easily wipes away. I am really baffled at how the steamer on the informercial cleaned everything, but yet mine did NOTHING!! I guess it was the magic of television. If you do want to try this piece of crap, buy it at Bed, Bath, and Beyond. That way you can easily return it, I know I will!
