ABSTRACT:
A method for washing a hollow fiber membrane used for blood dialysis, comprising washing the inner wall of the hollow fiber with a clearing solvent comprising, as a main component, a specific aliphatic hydrocarbon having a boiling point of 110-240.degree. C. and a flash point of not less than 21.degree. C. According to the present invention, the lipophilic liquid contained in the core part of the hollow fiber can be removed selectively without removing the glycerol filled in the pores of the hollow fiber membrane. In addition, the method of the present invention is free of the problems of flammability and pollution of global environment.
