  • Cleaning compositions for use with calcite-based stone
    Patent number: 10329522
    Abstract: A composition for cleaning hard surfaces includes from 3 to 20 wt-% dicarboxylic acid; from 3 to 25 wt-% surfactant; from 0 to 20 wt-% solvent; and water, and has a pH from 9 to 12.5. A ready-to-use solution of the composition includes from 0.1 to 5 wt-% dicarboxylic acid; from 0.1 to 5 wt-% surfactant; from 0 to 5 wt-% solvent; and water, and has a pH from 9 to 12.5. The composition is safe for use with calcite stone surfaces. A method of cleaning calcite stone surfaces comprises a use solution of the composition to the calcite stone surface, and rinsing, wiping, or scrubbing the surface. Another method of cleaning calcite stone surfaces comprises preparing a use solution by diluting the composition with water, applying the use solution to the calcite stone surface, and rinsing, wiping, or scrubbing the surface.
