well i got this for my birthday in march and this is the first time i got to use it. The ho had about 3 months of salt and sand on it, and i notices how gross it was yesterday when i was putting on my cross drilled rotors (good photo how-to on the way). The Mr.Clean thing is pretty cool, its got a knob to change from wash water to soap to deionized(filtered)water, and a tap on/off switch. you rinse your car, then wash it with the soap and scrub it as usual, then you rinse off the soap, and then you rinse it all down with the deionized water and just let it dry. No more drying the car, and it is spotless!!! saves me a good half hour everytime i wash the car now, I'd recommend it,
