I, WILLIAM BACKETT, of Old Kent Road, in the County of Surrey, Oilman,
do hereby declare the nature of the said Invention for "IMPROVED CLEANSING
POWDERS," to be as follows:-
My Invention consists in manufacturing a cleansing powder, by combining
"masons' dust or finely powdered hearthstone with an alkali, also reduced to
powder, the proportions being from about 90 to 95 parts by weight of masons'
'dust to 10 or 5 parts by weight of powdered alkali.
My Invention also consists in the employment of masons? dust alone, for
cleansing and renovating paint, removing grease, and other like cleansing
purposes.
My powders need simply be taken up by a wet or damp cloth, sponge or
other like article, and rubbed over the surface to be cleansed; a little clean
water is used to clear off after the application of the powder.
