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 SiO 2 , Al 2 O 3 , Fe 2 O 3 , In 2 O 3 , SnO 2 , ZrO 2 , B 2 O 3 and/or TiO 2 , and the hydrophobic substance is preferably chemically linked with the gel network. |
