Definitions

• the principal object of the present invention is to provide a new and novel chemical cleaner for primarily chemically removing metal marks from porcelain surfaces and the like.
• Another object of the invention is to provide a chemical cleaner composition particularly useful in removing aluminum marks from the surfaces of porcelain sinks and the like.
• the aforesaid stains and marks can be removed by moist contact with a metal peroxide cleaning agent, such as, e.g., calcium peroxide, either with or without scrubbing.
• a metal peroxide cleaning agent such as, e.g., calcium peroxide
• a surfactant and/ or an abrasive for mild scouring may, as optional additional ingredients, also be employed.
• removal of the aforesaid stains and marks is readily accomplished by contact with the essentially pure peroxide cleaner alone, it is contemplated and preferred for convenience and economy of materials that the peroxide be employed in a dilute cleaning composition together with the surfactant and a diluent material as a filler or abrasive.
• the present invention comprises in practice a dry free flowing chemical cleaning composition consisting essentially of from about 1 to about 6 weight percent of an alkaline earth metal peroxide as a chemical cleaning agent, and from about 0.5 to about 5.0 weight percent of a surfactant, such as, e.g., a commercial detergent, the balance being a bulk diluent serving either as an inert filler, or as an abrasive substance for scouring.
• a surfactant such as, e.g., a commercial detergent
• the present novel cleaning composition will contain about 1 percent of the alkaline earth metal peroxide, calcium peroxide being preferred, and from about 2 to 3 percent of a detergent, the balance being a finely divided abrasive.
• Alkali metal peroxides such as e.g., sodium peroxide, and lithium peroxide may also be used as the metal. peroxide of the present invention with excellent results, particularly sodium peroxide.
• the alkaline earth metal peroxides are preferred since they are much more stable and are thus superior for use in a dry, free flowing, stable cleaning composition. Examples of alkaline earth metal peroxides which may be used include: calcium peroxide, barium peroxide, and strontium peroxide.
• metal peroxide as used herein includes the alkali metal and alkaline earth metal peroxides.
• the detergent material used in the present composition may be any compatible commercial cationic, anionic or nonionic detergent or surfactant. This material when moistened or contacted with water aids in the cleaning of the stains or marks in the normal manner. Examples of classes of these materials include: quarternary alkyl ammonium salts, alkylaryl sulfonates, amine oxides and amides.
• Abrasives which may be used, either singly or in combination, as a scouring agent in the present novel cleaning composition may be any abrasive in a very finely divided, powder-form, which is compatible with and nondetrimental to the user and to the surface desired to be cleaned.
• An example of a suitable and common abrasive includes ground crystalline mica, or finely divided pumice.
• the above novel cleaning composition cleans, e.g., the aforesaid aluminum marks from sinks, with or without scouring, in a rapid, eflicient and convenient manner.
• the composition is dry, free flowing, and is reasonably stable as to peroxygen value. It employs commonly available ingredients, is easy to prepare, and is effective in its action to remove or minimize metal stains, marks, and the like, such as aluminum marks.
• a commercial household cleanser containing a chlorine bleach, a surfactant and an abrasive was contacted with the wetted portion of the sink so marked. N0 scouring or rubbing was employed.
• a cleaning composition in accordance with the present invention comprising 1 percent CaO and 99 percent of an abrasive filler of calcium carbonate was prepared and applied generously to a wetted portion of a white porce- 3 lain sink which had been marked up with aluminum foil as in Example 1. After 5 minutes standing, the sink was flushed with water. The aluminum marks were all removed.
• Example III The procedure of Example 11 was repeated except that the composition comprised about 2.5 percent of C210 and 97.5 percent of the abrasive. Again the marks were rapidly and effectively removed.
• EXAMPLE IV A composition as in Example II was prepared and similarly applied to an aluminum marked sink, except that the composition contained about 6 percent CaO No scrubbing was employed. After about 2 minutes the sink was rinsed with water. The aluminum marks were very effectively all removed.
• EXAMPLE V Various compositions were prepared and tested as in Example II above, except that Na O SrO and BaO were used instead of calcium peroxide. In each case the aluminum marks were effectively removed, especially in the case of sodium peroxide.
• compositions in accordance with the present invention varying as to amount and kinds of metal peroxides, detergents, and abrasives, may be also prepared and employed to remove various type stains and/ or marks from porcelain sinks.
• a method of removing aluminum stains and marks from a porcelain surface which comprises: applying to said stained and marked surface a cleaning composition in moist contact therewith, said composition as the active ingredient consisting essentially of a metal peroxide selected from the group consisting of alkali metal and alkaline earth metal peroxide, continuing moist contact of the cleaning composition with said porcelain surface for a period of time sufficient to eliminate said stains and marks, and removing said cleaning composition from said porcelain surface, thereby removing aluminum stains and marks therefrom.
