摘要：A method for washing an inner surface of a tubular permeable membrane whichcomprises:
a friction piece having a hardness of from about 10° to 30° measured according to JISK6301, 5-2 attached to an end of an elastic rod-like support, and
< P> operating the support to reciprocate the friction piece within the tubularpermeable membrane to thereby act a rub-washing force of from about 0.1 to 1.0kg/cm.sup.2 between the inner surface of the tubular permeable membrane and thefriction piece so as to remove contaminants adhered to the inner surface of the tubularpermeable membrane.
