<p>Limescale removing compositions are disclosed which comprise a C1-C6 linear or branched alkylsulfonic acid or mixtures thereof. Said alkylsulfonic acids are particularly efficient in removing limescale and they are furthermore stable to bleach/oxidants. Therefore, compositions can be formulated which further comprise acid-stable oxidant compounds. Also, mixtures of alkylsulfonic acids and sulfamic acid are particularly effective in removing limescale. The compositions of the invention are used to remove limescale from a variety of surfaces.</p> |
