Abstract
The present invention is directed to a method of enhancing the appearance of a soiled porous surface. The inventive method includes applying a concentrated, alkaline, cleaning composition to the soiled porous surface. This concentrated, alkaline, cleaning composition is then allowed to remain on the surface for a period of time before it is rinsed with water. After drying, a maintainer composition is then applied to the surface. The maintainer composition includes a pore-filling component. The cleaning composition includes an alkaline source and, optionally, a solvent.
