An advantageous effective cleaning solvent consisting essentially, according to one embodiment, of methyl ethyl ketone, methyl isobutyl ketone, isopropyl alcohol, toluene and n-butyl acetate, in certain ranges of proportions. Water also is included to aid in reducing the vapor pressure of the solvent. The composite vapor pressure of the solvent, at 20 DEG C., neglecting the vapor pressure contribution of water, is not greater than 35 mm of mercury. The invention solvent is particularly effective as a paint cleaner, e.g. for cleaning paint guns.
