ABSTRACT:
This invention pertains to the use of certain acrylic polymers in conjunction with other materials which characterize cleaners of alkaline earth metal scales and metal oxides and hydroxides, particularly citric acid, malic acid, and oxalic acid. Amount of the acrylic polymer is up to 100%, preferably 20 to 80%, based on the weight of a cleaner composition which includes the acrylic polymer. Suitable acrylic polymers are selected from homopolymers of acrylic and methacrylic acids, salts thereof, a copolymers of acrylic and methacrylic acids and salts thereof with 5 to 50% of one or more copolymerizable monomers, the acrylic polymers have molecular weight (M.sub.W) of 500 to 100,000.
