Abstract:
A cleaning mixture comprising polymeric resin pellets having a Rockwell R hardness of 85 to 140, water, and a surfactant salt comprising at least one of sulfonate salts, C6 to C36 carboxylic acid salts, or mixtures thereof, is used to purge the mixing device. The cleaning mixture has a pH of 6.0 to 9.0.
