Abstract
Aqueous alkaline cleaning concentrates and wash solutions are disclosed which comprise an alkali metal hydroxide, a water-conditioning acrylic polymer, an active chlorine source and a fatty or oily soil-dispersing amount of a low molecular weight aliphatic phosphonic acid containing at least two groups capable of forming anions under conditions of high pH, at least one of which is a phosphonic acid group. The wash solutions are particularly useful to clean cleaned-in-place food-processing equipment which has been fouled with greasy or oily soils.
