PURPOSE:To obtain a stabilizing soln. used in place of washing water and preventing well precipitation even during storage by adding a sulfite ion releasing compound and a specified compound to a stabilizing soln. CONSTITUTION:A sulfite ion releasing compound and at least one kind of compound selected among compounds represented by formulae I-V are added to a stabilizing soln. In the formulae I-V, each of R1-R3 is 1-6C alkyl, R4 is 1-20C alkyl and each of X1-X7 is halogen. Concrete examples of the compounds represented by the formulae I-V are represented by formulae I-1-V-1, respectively. |
