Abstract: A modular shelving system includes: a rail including a plurality of mounting holes; a plurality of shelves, each shelf including a pair of pivot pins; a plurality of pivots removably secured to the rail, wherein each pivot receives at least one pivot pin such that each of the shelves are rotatably supported on the rail between a corresponding pair of pivots; and a plurality of covers covering the rail and spanning the distance between each corresponding pair of pivots. The shelves each include a portion of a piece of visual art, such that when each of the shelves is positioned approximately vertically, the portion of the visual art is displayed and further such that when all of the plurality of shelves are positioned in the approximately vertical position, the entirety of the visual art is displayed.

Abstract: A range of novel biodegradable aqueous acid cleaning systems for removing limescale from surfaces, especially stainless steel and porcelain surfaces, wherein said system comprises a biodegradable aqueous acid system, said system having a pH of less than 7.0, said system comprising at least one of the following acids: i) iminodiacetic acid; ii) aspartic acid; iii) derivatives selected from N-alkyl, N-alkylaryl and N-cycloaliphatic derivatives of iminodiacetic acid; iv) derivatives selected from N-alkyl, N-alkylaryl and N-cycloaliphatic derivatives of aspartic acid; and v) C2-C10 polycarboxylic acids, said polycarboxylic acids containing a heteroatom in the main chain thereof, said heteroatom being selected from S, O and N; said system optionally comprising mixtures of said acids (i) to (v). The composition preferably comprises a surfactant to optimize the performance of said acid. Additional optional ingredients are selected from thickeners and co-builders and enzyme mixtures.
