A liquid cleaner composition comprising 0.1 to 10 %-wt of one or more surfactants, 0.4 to 1 %-wt of one or more rheology modifier copolymers, and water, whereby the composition has a pH of between 8 and 13 and whereby the one or more rheology modifier copolymer are selected from the group of copolymers of the formula wherein a, b, c, and d represent the percentage by weight that each repeating unit or derived monomer is contained within the copolymer, whereby a ranges from 0.5 to 25% by weight of the copolymer; b ranges from 70 to 98% by weight of the copolymer; c ranges from 0 to 15% by weight of the copolymer; and d ranges from 0 to 5% by weight of the copolymer; and whereby A is a macromonomer comprising at at least one end a polymerisable group reactive during polymerisation with at least one of B, C, and D monomers, the polymerisable group at the at least one end of the macromonomer being attached to a chain formed of a homo- or co-polymer of C 1 -C 10 alkyl acrylates, C 1 -C 10 alkyl methacrylates, methacrylic acid, acrylic acid or combinations thereof, the macromonomer having a number average molecular weight ranging from 500 to 10,000; and B is acrylic or methacrylic acid or a salt thereof; C, when present, is a polyacidic vinyl monomer selected from the group consisting of maleic acid, fumaric acid, itaconic acid, citraconic acid, mesaconic acid, combinations thereof and anhydrides and salts thereof; and D, when present, is a cross-linking monomer for introducing branching and controlling molecular weight, the cross linking monomer comprising polyfunctional units carrying multiple reactive functionalisation groups selected from the group consisting of vinyl, allylic and functional mixtures thereof, and whereby the groups A, B, C and D are covalently bonded one to another in a random, a block, or a cross-linked copolymer format. 0.1 to 10 %-wt of one or more surfactants, 0.4 to 1 %-wt of one or more rheology modifier copolymers, and water, a ranges from 0.5 to 25% by weight of the copolymer; b ranges from 70 to 98% by weight of the copolymer; c ranges from 0 to 15% by weight of the copolymer; and d ranges from 0 to 5% by weight of the copolymer; A is a macromonomer comprising at at least one end a polymerisable group reactive during polymerisation with at least one of B, C, and D monomers, the polymerisable group at the at least one end of the macromonomer being attached to a chain formed of a homo- or co-polymer of C 1 -C 10 alkyl acrylates, C 1 -C 10 alkyl methacrylates, methacrylic acid, acrylic acid or combinations thereof, the macromonomer having a number average molecular weight ranging from 500 to 10,000; and B is acrylic or methacrylic acid or a salt thereof; C, when present, is a polyacidic vinyl monomer selected from the group consisting of maleic acid, fumaric acid, itaconic acid, citraconic acid, mesaconic acid, combinations thereof and anhydrides and salts thereof; and D, when present, is a cross-linking monomer for introducing branching and controlling molecular weight, the cross linking monomer comprising polyfunctional units carrying multiple reactive functionalisation groups selected from the group consisting of vinyl, allylic and functional mixtures thereof,
