This invention relates to a method for cleaning bituminous asphalt- and tar-coated equipment, using combinations of alkyl esters with terpene cosolvents and/or surfactants. The specific invention is the use of ester solvents in combination with terpene solvents, optionally with emulsifiers and other additives. The combination of the two is found surprisingly to exhibit the excellent solvency of terpene solvents, but with the slower evaporating rate and higher flashpoint properties of ester solvents.
