A process for making a product with a long-lasting easily cleanable surface is described. By said process, there is applied to the surface a mixture comprising a hydrolyzable, network-forming gel and a hydrophobic substance. The gel is preferably formed from SiO2, Al2O3, Fe2O3, In2O3, SnO2, ZrO2, B2O3 and/or TiO2, and the hydrophobic substance is preferably chemically linked with the gel network.
