Homemade Carpet Shampoo 1 1/2 scoops Oxyclean 1/4 cup white vinegar 1/4/ cup Febreze (or other generic spray) Mix together with a gallon of hot water and add to machine. Any vinegar smell will fade away quickly, although my friend didn't notice any smell at all. She said this worked great on dog stains and odors.
Accidentally Green: Two safe, homemade stain removers - The vinegar/soap/water mixture is great on stains. I keep a spray bottle in the laundry room that I use whenever something spills on the couch or carpet. I skip the cornstarch step. So far, it's gotten everything up except for the full cup of coffee. That left a little mark. :P
