A substantially stable homogenous water-based coating remover composition comprising: (a) from about 7.2 to about 19.6 percent by weight of N-methyl-2-pyrrolidone; and (b) from about 12.15 to about 47.6 percent by weight of at least one mononuclear aromatic hydrocarbon; and (c) from about 7 to about

A substantially stable homogenous water-based coating remover composition comprising: (a) from about 7.2 to about 19.6 percent by weight of N-methyl-2-pyrrolidone; and (b) from about 12.15 to about 47.6 percent by weight of at least one mononuclear aromatic hydrocarbon; and (c) from about 7 to about 15 percent by weight of a glycol ether selected from tripropylene glycol mono (C1-C4) alkyl ether and diethylene glycol monobutyl ether; and (d) from about 0.225 to about 2.8 percent by weight of an alkanolamine; and (e) from about 0.297 to about 0.616 percent by weight of a hydroxypropyl cellulose thickener; and (f) from about 30 to about 55 percent by weight water.
