Abstract:
The present invention relates to the use of at least one alkane sulphonic acid, with formula R—SO3H, where R represents a saturated, linear or branched hydrocarbon chain, comprising 1 to 4 atoms of carbon for removing rust from all types of surface, in particular from metal surfaces, specifically iron, steel and others. The invention also relates to a method for cleaning rust from all types of surfaces using at least one alkane sulphonic acid.
