"
I totally believe in ASACLEAN products. We have used it for many years. We purge out a 180-oz. barrel, going from black nylon, glass-filled, to clear polypropylene in just a matter of a couple of purges. We also use ASACLEAN for a maintenance program for pulling screws. EX Grade is an unbelievable product for pulling a screw. Screw and barrel come out clean, material unwraps on the screw perfectly, and we are back in operation in just a few minutes. "
