Best Carpet Cleaner?

Question:Can anyone give me any ideas on the best carpet cleaner to use to remove pet stains? Our mother dog had some puppies and they made a mess of the carpet. Tried using the machine from Wal-Mart and it's still stained. Don't relish the idea of paying Stanley Steemer $500.00. HELP! Got company coming.

I recommended "Holy Cow" Its an all in one cleaner in a squirt bottle sold at walmart for a $1.80. It's neon pink, with utters and lipstick on..Get three of these, and mix with 4 cups hot water. It did the trick for me. I have three kids ages 6, 3, 14 months, so our carpet gets the wear, and stains.. (and my three year old is potty training) and it worked great. Best of all its all its all natural and safe with kids and animals. Good Luck.
