Acidic cleaning composition, useful for sensitive hard surfaces, particularly marble, includes divalent cations that form a carbonate having a lower solubility product than calcium carbonate

摘要

In a cleaning composition (A) of pH 2-6, comprising divalent cations (X) that form a sparingly soluble carbonate (B), the new feature is that (B) has a smaller solubility product (Ksp) than calcium carbonate.
