  • Patent number: 8338354
    Abstract: A manual spray cleaner for removing dirt and stains from fabrics and carpets comprising a spray bottle having two separate chambers and a single dispensing spray outlet for dispensing controlled amounts of liquids from each of the chambers. One of the chambers has a fabric/carpet cleaning composition therein and the other chamber has an oxidizing composition that enhances the cleanability of the fabric/carpet cleaning composition. The fabric/carpet cleaning composition and the oxidizing composition are simultaneously drawn from their respective chambers and mixed together at the time that they are dispensed from the spray bottle. At least one of the oxidizing composition and the fabric/carpet cleaning composition includes a fabric/carpet protectant. The two compositions are mixed before or after they are sprayed from the bottle. The two compositions can be pressurized with an aerosol propellant or drawn from their respective chambers by a mechanical pump.
