In laundering with ordinary home washing machines, various types of dirt accumulate inside the washing machine, including dirt removed from clothing and undissolved laundry detergent or, if soap is used, soap residue. This dirt produces a damaging effect in that it soils the clothing that is washed next. To deal with this type of laundry damage, in the present study we performed experiments aimed at developing a washing machine tub cleaner that would eliminate the damage. As a result, we were able to develop a product that, compared with the products on the market, was less affected by the constituent material of the washing machine tub, the water temperature, and the hardness of the water.
