BACKGROUND
It is known in the art to utilize organic solvents
for removing organic residues from inorganic surfaces.
Specification, page 1, lines 8-11. In processes which utilize
organic solvents, an organic residue is contacted with a quantity
of organic solvent until all of the residue has dissolved. Id.
at lines 14-16. Organic residues may result from, e.g., the
processing of organic chemicals, pharmaceuticals and foodstuffs
which adhere to surfaces such as metal, ceramic, glass or

environmental considerations have made the use of organic
solvents less desirable and economically feasible. Id., page 1,
line 23 - page 2, line 10. Thus, there has been an effort to

materials are water soluble and, therefore, removable with water-
