To provide an excellent soil purifier composition capable of effectively washing soil contaminated with oils, particularly petroleum-based compounds such as heavy oil, especially soil contaminated with C heavy oil. (A1) It contains at least one of a compound represented by the following general formula (1) and a compound represented by the following general formula (2), and (B) an organic amine compound. It is a soil purifier composition. R 1 —O— (AO) n —H (1) R 2 —CO— (AO) n —O—R 3 (2) However, the general formula (1) and the general formula (2), R 1 and R 2 each represents a straight-chain or branched alkyl group having 8 to 16 carbon atoms, R 3 is a straight of 1 to 8 carbon atoms A chain or branched alkyl group, AO represents an oxyalkylene group having 2 to 4 carbon atoms, n represents an average added mole number of AO, and represents a number of 2 to 8.
