  • Patent number: 6333299
    Abstract: The present invention relates to liquid acidic compositions suitable for removing limescale-containing stains from a hard-surface, comprising an acid, from 0.001% to 20% by weight of the total composition of a polysaccharide polymer and from 0.001% to 20% by weight of the total composition of a vinylpyrrolidone homopolymer or copolymer, said composition being packaged in a spray type-dispenser. Such a composition provides improved shine to the surface treated while exhibiting effective limescale removal performance. The use of a polysaccharide polymer and a vinylpyrrolidone homopolymer or copolymer, in a liquid acidic composition being packaged in a spray-type dispenser, to treat a hard-surface, reduces or even prevents the formation of watermarks and even limescale deposits on said hard-surface after said hard-surface has first been treated with said composition and subsequently comes in contact with water.
