Abstract:
A highly alkaline detergent is described which includes the use of a carboxylic acid terpolymer in combination with an alkali metal hydroxide. The detergent maintains cleaning functions and also prevents hard water scaling at application temperatures, for example at temperatures of between about 145-180 degrees Fahrenheit and, for example, at a pH of 9.5 to about 13.
