A process for removing contaminants from the surface of a substrate comprises contacting the substrate with a cleaning composition comprising at least one mono-, di-, or trialkoxy-substituted perfluoroalkane, perfluorocycloalkane, perfluorocycloalkyl-containing perfluoroalkane, or perfluorocycloalkylene-containing perfluoroalkane compound, the compound optionally containing additional catenary heteroatoms. The compounds exhibit good solvency properties while being environmentally acceptable.

Um processo para remover os contaminadores da superfície de uma carcaça compreende contatar a carcaça com uma composição da limpeza que compreende ao menos um mono -, di -, ou o perfluoroalkane trialkoxy-substituído, perfluorocycloalkane, perfluorocycloalkyl-contendo o perfluoroalkane, ou perfluorocycloalkylene-contendo o composto do perfluoroalkane, o composto que contem opcionalmente heteroatoms catenary adicionais. Os compostos exibem propriedades boas do solvency ao ser ambiental aceitáveis.
