ABSTRACT:
A solvent that will remove all types of commercially available water soluble polymers by breaking the covalent bonds within the polymer molecules such that these polymers can then be removed from all surfaces and equipment completely and safely by washing away with water.
The solvent consists of (in a 21/2 gallon concentrated solution) 4% of ammonium chloride, 29% of ammonium hydroxide, and 67% water.
