not from experience myself....but told wife about it (she has the experience....LOL) and she said it would probrably take it out but its best to use right away and the other thing you gotta watch out for is taking out the color in your carpet as its pretty strong. She suggested you try it in a in-conspicuous area first. She has also heard great things about Woolite Carpet cleaner but has never tried it yet.....
actually any good brand of beverage with a high alcohol content will remove it...just drink it and pass out and the stain is gone till you wake up again...repeat application as many times as needed..
we have dogs and with the accidents that happened when they were pups wee(pun)
found capture carpet cleaner to work great .. sears and rona used to sell it
