Homemade Carpet Shampoo - revised the recipe as follows for use in regular size Rug Doctor: 2 Tbls. Baking Soda, 2 Tbls. Borax, 2/3 cup White Distilled Vinegar. Be sure to read my review in the comment section.
Use Mr. Clean in a Rug Doctor carpet shampooer. Cheaper than the brand name solution. $3 v/s $20. My carpets are off white. The color in this solution will NOT stain your carpet. See the treated side of the cola stain? I used Mr. Clean 'Gain' scented. My whole house smells like Gain dryers sheets! Use 1/2 cup of Mr. Clean per 2 gallons of hot water.
