Abstract:
1. A method for preparing a cleaning solution, comprising steps of: providing a bucket with a first indicator corresponding to a first volume, with a mop wringer provided on the mop bucket; providing a secondary reservoir arranged at a height above the first indicator, the secondary reservoir having a second indicator corresponding to a second volume, the secondary reservoir having a metering orifice in a base thereof; providing a liquid chemical additive having a known viscosity and preferred dilution for use; filling the bucket to a level of the first indicator with a cleaning liquid; and filling the secondary reservoir to a level of the second indicator with the liquid chemical additive, and allowing the liquid chemical additive to drain through the metering orifice into the cleaning liquid in the bucket; wherein the first and second volumes of the cleaning liquid and liquid chemical additive in the bucket and secondary reservoir, respectively, produce the preferred dilution of the liquid chemical additive in the cleaning liquid; and wherein dimensions of the metering orifice and the viscosity of the liquid chemical additive are selected so that the secondary reservoir can be filled with the liquid chemical additive to the level of the second indicator before any, or any significant, amount of the liquid chemical additive passes through the metering orifice, and maintaining the secondary reservoir stationary relative to the bucket during filling and emptying of the secondary reservoir.
