Cinder:
Tell yer dad if he gets the Oxy Clean stuff to use 1 scoop full and really hot water in a spray bottle. Spray in on the oops and let it sit for a minute or two, then blot with a dry towel. Mom sez it works so good, it makes her want to do the whole carpet. PS, she also uses it in the big steamcleaner thingie when we come in the house with muddy paws. Take er easy. Max the wonder dog.
