Masterblend Soap Free Carpet Cleaner
Masterblend Soap Free is a carpet and upholstery cleaning chemical that I highly recommend. As the name implies, it is a soap free cleaner that can be used both as a pre-spray and as a rinse. It does an amazing jobs of cleaning carpet and leaves little if any residue. This means that carpets cleaned with soap free get clean and stay clean longer.
Professional cleaners can add 3 cups of soap free into a 5 gallon mix container and meter it at 2-4 gallons per hour. As a prespray, mix 2 ounces per gallon.
