I bought Dr. Amos Shock It Clean Extreme & it did nothing, I was so surprised as the demo's show it taking off a lot...I tried it as a rug spot cleaner, on the bathroom counters, just no results....I did not send back as it would have been too expensive for shipping
I did get the Whip It from a demo at my local BJ's & was really happy, took off old carpet stains...haven't tried it on other things yet
I did try the Dr Amos full strength & it still didn't touch the carpet stains or outdoor furniture...
