A cleaning chemical dispensing system comprising : a liquid chemical additive having a predetermined viscosity; a mop bucket (2); a mop wringer (6) provided on the mop bucket; a first indicator (2a) which indicates a first volume of cleaning liquid in the mop bucket; and a secondary reservoir (15) for the liquid chemical additive, the secondary reservoir (15) being at a position spaced above the first indicator (2a), and having a base (115), one or more upstanding walls (116) continuously contiguous with and fully surrounding the base (115), an opening (117) opposite the base (115) for pouring the liquid chemical additive into the secondary reservoir (15), a metering orifice (17) formed in the base (115), and a second indicator (118) indicating a second volume for the liquid chemical additive which corresponds to the first volume of the mop bucket (2) so as to provide a required ratio of liquid chemical additive to cleaning liquid, the metering orifice (17) being dimensioned to correspond to the predetermined viscosity of the liquid chemical additive, so that the liquid chemical additive can be poured into the secondary reservoir (15), via the opening (117), up to the second volume indicated by the second indicator (118) before any significant amount of the liquid chemical additive passes through the metering orifice (17).
