Claim 1 A liquid hard surface cleaning composition comprising melamine foam fibres and having a pH from about 7 to about 12, wherein said composition is packaged in a container, wherein said melamine foam fibres comprise melamine and formaldehyde, the melamine foam fibres releasing substantially no formaldehyde over prolonged periods of time, the melamine fibres having a diameter below about 30 μm and a length below about 250 μm, wherein the composition comprises from about 70% to about 99.5%, by weight of the total composition, of water and from about 0.01% to about 20%, by weight of the total composition, of a surfactant. ### Claim 2 (depends on 1) A liquid hard surface cleaning composition according to claim 1, wherein said liquid hard surface cleaning composition is packaged in a container having a porous flexible sponge material mounted in an aperture of said container. ### Claim 3 (depends on 1) A liquid hard surface cleaning composition according to claim 1, wherein said composition comprises at least about 0.5%, by weight of the total composition, of melamine foam fibres. ### Claim 4 (depends on 1) A liquid hard surface cleaning composition according to claim 1, wherein said composition comprises a suspending aid or a mixture thereof. ### Claim 5 (depends on 1) A liquid hard surface cleaning composition according to claim 1, wherein said composition comprises a formaldehyde scavenger, selected from the group consisting of sodium bisulfite, urea, cysteine, cysteamine, lysine, glycine, serine, carnosine, histidine, glutathione, 3,4-diaminobenzoic acid, allantoin, glycouril, anthranilic acid, methyl anthranilate, methyl 4-aminobenzoate, ethyl acetoacetate, acetoacetamide, malonamide, ascorbic acid, 1,3-dihydroxyacetone dimer, biuret, oxamide,

benzylamine, hydroxycitronellol, cyclohexanone, 2-butanone, pentanedione, dehydroacetic acid, and chitosan, and a mixture thereof. ### Claim 6 (depends on 1) A liquid hard surface cleaning composition according to claim 1, wherein said composition has an alkaline pH and comprises a formaldehyde scavenger selected from the group consisting of ammonium chloride, sodium hydroxide dicyanodiamide, acetoacetamide and organic polyamine, such as polyvinyl amine, and mixtures thereof. ### Claim 7 (depends on 1) A liquid hard surface cleaning composition according to claim 1, wherein said composition comprises less than about 200 ppm of formaldehyde in solution, per 1% by weight of melamine foam fibers present in said composition. ### Claim 8 (depends on 1) A liquid hard surface cleaning composition according to claim 1, wherein said composition comprises less than about 200 ppm of formaldehyde in solution, per 1% by weight of melamine foam fibers present in said composition, upon storage. ### Claim 9 A container containing liquid hard surface cleaning composition comprising melamine foam fibres and having a pH from about 7 to about 12, wherein said melamine foam fibres comprise melamine and formaldehyde, the melamine foam fibres releasing substantially no formaldehyde over prolonged periods of time, the melamine fibres having a diameter below about 30 μm and a length below about 250 μm, wherein the composition comprises from about 70% to about 99.5%, by weight of the total composition, of water and from about 0.01% to about 20%, by weight of the total composition, of a surfactant. ### Claim 10 (depends on 9) A container according to claim 9 having a porous flexible sponge material mounted in an aperture of said container. ### Claim 11 A process of cleaning a hard surface with a liquid hard surface cleaning composition comprising melamine foam fibres and having a pH from about 7 to about 12, wherein said process comprises the steps of dispensing said liquid hard surface cleaning composition from a container containing said liquid hard surface cleaning composition and thereafter cleaning said hard surface, wherein said melamine foam fibres comprise melamine and formaldehyde, the melamine foam fibres releasing substantially no formaldehyde over prolonged periods of time, the melamine fibres having a diameter below about 30 μm and a length below about 250 μm, wherein the composition comprises from about 70% to about 99.5%, by weight of the total composition, of water and from about 0.01% to about 20%, by weight of the total composition, of a surfactant.
