Abstract

Alkaline spray-on cleaners that can be delivered by pump or pressurized gas aerosol spray have been made with reduced choking mists are disclosed. The cleaning composition comprises the use of anti-mist components consisting of large anionic copolymer comprised of acrylamide and AMPS (acrylamide-sodium 2-acrylamido-2-methylpropane sulfonate), and polyethylene oxide polymers that create non-Newtonian solutions. The composition also includes a surfactant, and a source of alkalinity.
