A coating composition of an alkoxy silane reacted with the surface of a glass substrate and a cleaning composition and method for cleaning said glass area is disclosed. The coating provides water repellency, durability and ease of cleaning to a glass or other siliceous surface. The coating is formed by applying an excess of an alkoxy solution containing a sulfuric acid to a glass surface with an excess of solution being applied. Preparatory to such coating application, the glass, especially if its surface is a weathered (non-virgin) surface, is cleaned vigorously with a cleaning solution containing water, phosphoric acid, hydrofluoric acid and sulfuric acid.
