Abstract
A one-step cleaning and water repellent treatment is provided. An alkaline-stable cleaning solution is mixed with an aqueous solution of alkali metal organosiliconates and applied to porous inorganic surfaces as a one-step cleaning and water repellent treatment. The mixture has been found to be stable and compatible. The one-step cleaning and water repellent treatment functions to simultaneously clean and protect porous inorganic surfaces and, thus, reduces the cost and time necessary to clean and protect such a surface.
Claims8
A one-step cleaner and water repellant composition for porous inorganic surfaces consisting essentially of:
- (a) an alkaline-stable cleaning composition consisting essentially of
- (i) at least one bleach selected from chlorine bleach and oxygen bleach;
- (ii) at least one surfactant;
- and
- (iii) at least one pH stabilizer, wherein the pH of said alkaline-stable cleaning solution is in the range of 10 to 14;
- (b) an alkali metal alkylsiliconate, and
- (c) water;
- wherein the alkaline-stable cleaning composition and the alkali metal alkylsiliconate are compatible in water, and wherein said one-step cleaner and water repellant composition cleans said surface and imparts water repellency to said surface upon application to said surface.
