Carpet Spot Remover

I decided to clean our carpets today. I realized once I was all set up to clean that I didn't have any carpet cleaner to pre-treat the spots. I went online looking for a "natural" spot remover. Hoping that I had something in the house I could use. Sure enough. A website (can't remember which one now) said to put baking soda down on the spots and rub the baking soda in real well. Then vacuum up the baking soda. It worked great. The spots are gone after I did this and cleaned the carpets!
