~DIY carpet cleaner for machines~ I just made a gallon of this carpet cleaner. Add 1/4 cup vinegar, 4 tbsp dish soap, 4 tbsp softener and 1/4 cup peroxide in a measuring cup. Stir it. Then add it to an almost full gallon of warm water. Then slowly add warm water to top it off. Gently shake the jug to mix, avoid suds and bubbles. Add to the cleaning compartment like you would normal cleaning solution. I made it for pennies. It worked great on my carpets and smells good too.
