Abstract: In fabric laundry procedures, commercial and household laundry detergent compositions commonly contain an optical brightener composition. Brighteners adjust the optical properties of the fabric in such a way that the fabric appears to be white even after repeated washings. Often white fabrics can yellow during use. Fluorescent optical brighteners having an optical blue aspect, mask the yellowing of the fabric. Common laundry detergents fail to have sufficient brightening capacity to brighten heavily soiled white cotton items used in household, commercial, institutional or fast-food food surface. A process for improving the whiteness of soiled white cotton, preferably terry cloth, items involves contacting the soiled white fabric item with a presoak containing an effective proportion of a fluorescent optical brightener composition, removing the item from the presoak and separating the presoak composition from the fabric item producing an extracted item.

Abstract: A method of removing from a stainless steel surface a difficultly removable soil originating from an animal or vegetable source comprising the step of contacting the soil adhered to the surface with an amount of a noncorrosive chemical composition effective to ultimately essentially chemically remove the soil from at least 51% of the surface. The difficultly removable soils that can be removed by the method of the invention are otherwise ultimately essentially chemically removable from at least 51% of the surface, at the temperature at which the above contacting step is conducted, only by contact with at least one corrosive chemical composition. The method is both safe for the user and highly effective to remove the above-described soils.

Abstract: A dispensing apparatus and method for dispensing detergent in a warewash machine. The rinse water spray system or an alternate water source is monitored to determine if water is being supplied to the warewash machine. Once water is sensed being supplied to the machine, the apparatus determines whether the water is being supplied for a rinse cycle or a fill cycle. The amount of detergent dispensed is controlled based upon the determination of whether the water is being supplied in a rinse cycle or a fill cycle. If the apparatus determines that the water is being supplied for a rinse cycle, a make-up amount of detergent is dispensed upon completion of the rinse cycle. If the apparatus determines that the water is being supplied for a fill cycle, the washtank is precharged with the desired concentration of detergent during the fill cycle.

Abstract: A dispensing apparatus for automatically dispensing detergent into a laundry machine. The electrical current drawn by the laundry machine is monitored by a detecting device to detect when the electrical current exceeds a predetermined threshold current. When the electrical current exceeds the threshold current, the detecting device transmits a signal indicating that detergent should be conveyed from the detergent supply to the washtub of the laundry machine by a conveying device. The signal is delayed for a predetermined period of time by a delay timer. After the delay, the conveying device is controlled to convey the detergent. If the washing process is interrupted for less than a predetermined period of time, a dwell timer prevents multiple conveyance of detergent into the washtub.

Abstract: A composition for the pre-treatment in aqueous form of a surface, preferably of an oven, which is subjected to heat and is liable to soiling by baked-on organic food deposits. A food-safe, inorganic thickening agent, in an amount sufficient so that the composition is capable of forming a continuous coating adhered to all desired portions of the preferably cleaned surface, which coating also remains continuous as the coating dries, preferably by heating, is combined with an alkaline, water-soluble inorganic salt in an amount sufficient so that the composition is readily removable with water or an aqueous solution after the composition has been dried and soiled. The composition forms a continuous film after drying. After the film becomes soiled, it can be readily removed by contact with water or an aqueous solution.

Abstract: Acidic floor cleaning compositions are employed to improve the coefficient of static friction of floors, especially quarry tile, in environments conducive to the buildup of slippery-when-wet films, e.g., fast food restaurants. Such compositions, preferably buffered and containing surfactants, also improve the appearance of the floor by maintaining the floor free of ugly film without any significant attack on the grout or the tile.
