Cleaning agent, cleaning agent set, bath water additive, and circulation purification method

摘要

Problem to be solved: to provide a cleaning bath of a circulating bathtub capable of removing an organic biofilm (biofilm) generated in a circulating bath.The cleaning agent is characterized by containing a sugar alcohol. Washing of the circulating tub 1 using a detergent containing sugar alcohol circulates between the bathtub 10 and the circulating pipe 20 in the circulating tub 1. Then, the alcohol film contained in the cleaning agent is suitably removed from the biofilm formed in the circulating pipe 20 of the circulating bath 1.Diagram
