A process for cleaning or dewatering a surface in which there is applied to the surface a washing composition containing a volatile methyl siloxane such as hexamethyldisiloxane or octamethyltrisiloxane, and an agent for enhancing cleaning or dewatering such as a glycol ether or surface active agent. While the surface is still wet with the washing composition, it is rinsed with an azeotrope containing hexamethyldisiloxane or octamethyltrisiloxane, and 2-pentanol, 2-methyl -1-pentanol, 3-methyl-3-pentanol, 1-methoxy-2-propanol, 1-butoxy -2-propanol, 1-hexanol, n-propoxypropanol, or ethyl lactate. The surface is then dried or permitted to dry.
