1. A method of using a solid-layered bleach composition having at least two parts comprising a first part and a second part, comprising;

  • i) dissolving the bleach composition;

    ii) providing a specific surface;

    iii) contacting the surface with the dissolved bleach composition; and

    iv) cleaning the surface with the dissolved bleach composition;

    wherein said first part comprises,a) 0.001%-50% by weight of a hypochlorite selected from the group consisting of calcium hypochlorite, magnesium hypochlorite and mixtures thereof;

    b) a builder selected from the group consisting of carbonate, bicarbonate, sesquicarbonate and mixtures thereof;

    c) a water-soluble polymer, whereas said water-soluble polymer is selected from the group consisting of a polycarboxylate, sulfonated carboxylate, polysulfonate, polyvinylpyrrolidone, polyquaternary ammonium salts, copolymers and mixtures thereof;

    d) at least 30% by weight of an acid selected from the group consisting of sulfonic acid, polysulfonic acid, carboxylic acid, dicarboxylic acid, polycarboxylic acid, acid sulfate, acid phosphate, phosphonic acid, and mixtures thereof;

    e) optionally, a filler selected from group consisting of chloride, sulfate, phosphate, silicate, borate, nitrate, chlorate, aluminate, silica-aluminate, hydroxide, and oxide compounds of alkali metals, alkaline earths, aluminum, zinc and tin including hydrates, mono, di and tribasic compounds, mixed salts, borates, clays, zeolites and mixtures thereof;

    f) optionally, a water-swellabie polymer selected from the group consisting of cross-linked polycarboxylate, cross-linked polysulfonate, cross-linked carboxymethyl cellulose, cellulose, sodium carboxymethylcellulose, and mixtures thereof;

    g) optionally, desiccants, solid processing aids, colorants, agglomeration aids, binders, glidants, corrosion inhibitors, and mixtures thereof; and

    h) wherein said first part does not contain sodium hypochlorite, lithium hypochlorite, potassium hypochlorite, sodium chlorite, chlorine dioxide, N-halogensted compounds, hydantoins, isocyanurates, carboxylic acids that also have hydroxyl, amino, amido, imino, or imido groups, enzymes; and

    wherein said second part comprising,a) a functional ingredient selected from the group consisting of a surfactant, a hydrotrope, a wetting agent, a dispersant, a penetrant a chelating agent, an odor absorbent, a fragrance, a flavoring agent, a sweetener, a colorant, a corrosion inhibitor, a viscosity modifier, a foam booster, a defoamer, a stain and soil repellant, a fluorescent whitening agent, an enzyme, a cloud point modifier, an anti-microbial agent, a sporolation agent, a catalyst, an activating agent, a therapeutic agent, and mixtures thereof;

    b) a builder or filler selected from the group consisting of a carbonate, a bicarbonate, a sesquicarbonate, a chloride, a sulfate, a phosphate, a silicate, borate, a nitrate, an aluminate, a silica-aluminate, a hydroxide, or an oxide compound of alkali metals, alkaline earths, aluminum, zinc and tin including hydrates, mono, di and tribasic compounds, mixed salts, a borate, a clay, a zeolite, and mixtures thereof;

    c) optionally acids, water soluble polymers, disintegrants, desiccants, solid processing aids, agglomeration aids, binders, glidants, preservatives, and mixtures thereof; and

    d) wherein said, second part does not contain any oxidant wherein said oxidant comprises hypochlorite, chlorite, chlorate, perchlorate, N-halo compound, chlorine dioxide, peracid, peroxide, peroxygen bleach and mixtures thereof.
