A toilet that includes a water tank having a vent hole; a bowl; and a system having a valve body connecting the tank and a fluid channel; a housing moveable relative to the valve body during a flush cycle to pass water from the tank into the bowl through the fluid channel, the housing having a bore that connects with the fluid channel; a fan in the bore that operates in first and second modes; a motor in the bore for rotating the fan in each mode; and a vent having an inlet fluidly connected with the bore and an outlet fluidly connected with the vent hole. In the first mode, the fan moves air from the bowl to the vent hole through the bore and vent; and in the second mode, the fan moves air from outside the tank to the bowl through the vent hole and bore.

The present invention relates to graffiti removal compositions and the use thereof for the removal of graffiti from surfaces. The compositions comprise (i) alkyl esters of one or more soybean oil fatty acids; (ii) one or more aliphatic diesters of dicarboxylic acids; (iii) one or more compounds of the formula R.sub.2C(0)OR.sub.3, wherein R.sub.2 is a C.sub.1-C.sub.20 alkyl and R.sub.3 is C.sub.1-C.sub.20 alkyl; and (iv) a surfactant.

The composition for cleaning disarticulated skeletons is a mixture of ammonia, hydrogen peroxide and water. The composition may further include ozone continuously pumped into the mixture while soaking the skeleton. The skeleton may initially be soaked in a composition having 7% ammonia by volume and 8-10% hydrogen peroxide by volume, the balance being water, e.g., for a period of ten days. The composition may be maintained at 20 C. and ozone may be continuously pumped during the ten-day period. If any grease remains, the bones may be soaked again, e.g., in a composition having 3% ammonia and 3% hydrogen peroxide for an additional seven days, again with continuous pumping of ozone at a rate of 200 mg/hr into the mixture, followed by rinsing with water and drying.

The present invention relates to a detergent composition comprising alkali metal carbonate, a chelant selected from the group consisting of MGDA, alkali metal tripolyphosphate, GLDA, and mixtures thereof, alkali metal percarbonate, and a peroxidation catalyst, wherein the molar ratio of chelant to alkali metal percarbonate is in the range of 1.8 to 3.4. The detergent composition is particularly suited for the removal of tea and coffee stains.

A method of treating a building for mold contamination including the steps of assessing and locating mold growth areas, constructing a containment barrier around the mold growth areas, vacuuming, abrading and surface treating the mold growth areas, ceilings, walls and window treatments with mold cleaner, replacing air filters from air handlers, removing all registers and vent grills in the treated areas and washing the vent grills with mold cleaner, vacuuming all registers and accessible ductwork, treating the heating and ventilation system, associated ductwork and wall cavities with an atomized mold cleaner, vacuuming all flooring, horizontal surfaces, walls, furniture and mattresses, re-vacuuming all flooring, re-treating the heating and ventilation system and associated ductwork with an atomized mold cleaner and re-treating the work area including any exposed wall cavities with an atomized mold cleaner, deconstructing and discarding containment barrier and reinstalling all registers and vent grills.

A material restoration system disclosed herein. The material restoration system includes a first composition (referred to herein as Composition A) and a second composition (referred to herein as Composition B). Composition A is a cleaning, stain-lifting, and rejuvenation product which is permeable into many construction materials (i.e. concrete). Composition A is capable of removing surface contaminants, including salt, surface rust, calcification and hard water byproducts, oxidation, and efflorescence. Composition A permeates into the material and acts to lift stains. Composition B is a surface applicant and can be used to resurface construction materials (particularly concrete) or fill voids and damage broken construction materials. Composition B has strong bonding properties and is able to provide structural benefits when used to fill cracks and chips.

A toilet that includes a tank configured to hold water from a water supply; a reservoir fluidly connected to the tank and configured to hold a cleaning compound comprising a chemical compound and water from the water supply; and an actuator configured to control a flush cycle of the toilet upon a first activation, the actuator including at least one nozzle fluidly connected to the reservoir and configured to discharge an amount of the cleaning compound external to the tank upon at least one of the first activation or a second activation.

The present invention relates to a detergent composition comprising alkali metal carbonate, a chelant selected from the group consisting of MGDA, alkali metal tripolyphosphate, GLDA, and mixtures thereof, alkali metal percarbonate, and a peroxidation catalyst, wherein the molar ratio of chelant to alkali metal percarbonate is in the range of 1.8 to 3.4. The detergent composition is particularly suited for the removal of tea and coffee stains.

A restoration system which is used to restore brick, glass, concrete, metal, plexiglass, and stone to their original color and preserve the materials. The restoration system includes a treatment composition overlay including a first-dry-part, a second-dry-part, a first-liquid-part, and a second-liquid-part. The first-dry-part is an acrylic based dry polymer. The second-dry-part is an acrylic based dry hardener. The first-liquid-part includes polymeric resin, water, acrylic polymer, and sodium. The second-liquid-part includes acrylic resin, water acrylic polymer, aqueous ammonia, and additives. The first-dry-part, the second-dry-part, the first-liquid-part, and the second-liquid-part are configured to be mixed to create a treatment composition overlay for restoring and preserving at least one surface.
