Does anyone have a recipe for homemade carpet cleaner?

A while back I was watching our local public educational television station fund drive and one of the gifts given was a set of household tips books. The man demonstrating the tips mixed a few ingredients together, put them in a foaming pump bottle and used the foam to clean carpet and upholstery. I'm looking for that recipe!

I kinow this is'nt exactly what you are looking for but I find that a little laundry soap and water is highly effective. If you want to put it in a foaming pump bottle you could. I bought a cute one for my son at meijers. Hope this helps!
