<p>Engine cleaner compositions are reported comprising a single phase solution comprising a polar solvent having a Hildebrand solubility parameter of about 10 cal ?1/2 cm -3/2¿ or greater; a non-polar solvent, immiscible with the polar solvent, having a Hildebrand solubility parameter of about 10 cal ?1/2 cm -3/2¿ or less; and a fugitive cosolvent having a higher evaporation rate than the polar solvent and the non-polar solvent. The engine cleaner compositions are suitable for cleaning internal combustion engines.</p> |
