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.
