Abstract: A method of treating the internal surface of a container for the storage of gas, such as a gas cylinder, that is made from or lined with aluminium or aluminium alloy. The method is characterised in that it comprises creating a freshly exposed aluminium surface, for example by the use of a wet grinding, in the presence of a surfactant. The surfactant is preferably derived from C 6 - C 18 carboxylic acids. The container for the storage of gas provides long-term gas stability. The internal surface of the container has a substantially continuous disturbed layer and is hydrophobic. It may also incorporate groups or species derived from the surfactant and/or comprise oxides or oxyhydroxides of aluminium.
