BEST carpet-with-thow-up clean up tip EVER. I have been doing this ever since I first read this post 4 years ago and IT WORKS LIKE A CHARM. I've even done it on a mattress and used the shop vac. "Professional carpet cleaners at Chem-Dry...shared a secret of the trade." With as many kids as we have, I am so glad I found this. Thought I'd share.
