Patented Dec, 8, 19250 COMPOSITIOK FQB CLEANING AIQ'D POLISHING SILVER.

E Drawing. Application filed November 9, 1921, Serial No. 514,018l Renewed October 24, 1825.

To all whom it may concern: Be it known that I, CATHERINE M. Human,

a citizen of the United States of America, residing at Seattle, in the State of Washington, have invented certain new and useful Improvements in Composition for Cleaning and Polishing Silver, of which the following is a specification. 1

This invention relates to a cleansing and 19 polishing composition, designed more particularly for cleaning and polishing silver,

though equally effective with other metallic surfaces or with glass.

The composition is made up of selected ingredients, which are associated in the composition for certain characteristics they are i nown to possess, their association however tending to a result not capable by any one of such selected ingredients.

For example, the castile soap and oxalic acid included in the composition have well knowncleansing properties, but in their association with the/other ingredients, they not only have the effect of cleansing the sur-- face of the article, but also tend to the formation of what may be termed a lacquer to thereby rotect'the cleaned and polished surface against dirt or marks in handling.

The improved composition is made up of 39 the following materials substantially in the proportions stated: Four pounds of Spanish castile soap; one-half pound of oxalic acid; three-quarters of a pound of bicarbonate of soda; one quart of a vegetable oil, such as $55 olive or cotton seed oil; nine gallons of water; and a sufficient quantity of the finest grade of Paris white to render the mass of paste-like consistency,-which is worked up to form blocks or a powder. $53 The composition in completed form is substantially a somewhat hardened paste-like mass, and is used by applying a. portion thereof, thru, the medium of a sponge or cloth, to the surface to be cleansed, followed bylproper rubbing with a dry or polishing 4 coth. v

The efiect of the composition is to cleanse the surface, removing all foreign matter therefrom, and thru the use of the oil, a certain. proportion of the ingredients remains on the surface somewhat in the nature of lacquer. Thus, the cleansed surface is brought to a high polish and such surface is effectively protected for an appreciable period against tarnishing'or marks, as in handling, er the collection of dirt thereon.

Thus with the composition, thesurface is cleanedv and a lacquer is deposited thereon, which while not only protecting the surface adds materially to the polished appearance 69 thereof. I

It is to be noted that Spanish castile soap is an ingredient of the composition. This particular well known type of-this material has been found to be the only character of castile soap which will secure the result desired, and while it cannot be definitely stated as to why the particular result is only possible with this character of castilc soap, it is nevertheless stated that other characters of 7 castile soap do not have the desired effect.

Claim: l

A cleansing and lacquer forming composition, consisting of four pounds of Spanish castile soap, one-half pound of oxalic acid,

three-fourths pounds of bicarbonate of soda, one quart or vegetable oil, nine gallons of water, and suificiejnt Paris white of extremely fine grade to substantiallyabsorb the liquid content of the mass. I
