The present invention relates to a liquid acidic composition suitable for removing limescale-containing stains from a hand-surface having a pH below 5, and comprising from 0.01 % to 20 % of the total composition of a sulfamic acid, from 0.01 % to 45 % by weight of the total composition of a second acid, and from 0.001 % to 10 % by weight of an acid-stable polymer selected from the group consisting of a polycarboxylate polymer, a sulphonated homopolymer of (poly) styrene, or a sulphonated copolymer of styrene with an ethylenically unsaturated comonomer, a vinylpyrrolidone homopolymer or copolymer, a polyalkoxylene glycol, and mixture thereof. These compositions provide improved shine to the surface treated as well as improved skin mildness to the user's skin while exhibiting effective limescale removal performance.
