how do those things work on upholstery? my cat pissed in my favorite chair - twice. i've tried all the home remedies (hydrogen peroxide, baking soda, resolve, white vinegar...) but they don't work. they did a nice job of taking the color out of that spot on the chair but the stink is still there.

have you used the bissell's on upholstery? the internet reviews say they break pretty easily...
