Procedure

The composition of claim 1 wherein the nonionic surfactant is the 8.5 molar ethoxylate of nonylphenol in a 6:1 (wt:wt) blend with triethanolamine in an amount of about 25 wt. %; the anionic surfactant is sodium dodecylbenzene sulfonate in an amount of about 5 wt. %; the solvent is ethanol in an amount of about 4 wt. % and the hydrotrope is the sodium salt of dicyclopentadiene sulfonate formed by bisulfite addition to dicyclopentadiene in alcohol/water solution at a pH of about 7.2 and in an amount of about 2 wt. %.
