Abstract
A dilutable cleaning composition comprises a pH-elevating component and a pH-lowering component, the composition being such that when it is mixed with water the pH-elevating component dissolves or disperses in the water thereby elevating the pH of the water to at least 8.5 and subsequently the pH-lowering component dissolves or disperses in the water, thereby lowering the pH of the water from at least 8.5 to not more than 4. When the water is at the raised pH, the cleaning composition is effective in removing proteinaceous or fatty soiling, and when the composition is at the lowered pH, the composition is effective at removing alkaline waste materials such as limescale. The cleaning composition is particularly suitable for use as a lavatory or hard surface cleaner.
