What is a washing machine cleaner?

Washing machine cleaner is designed to keep a washing machine running at its best. The cleaner removes soap or detergent buildup that may be in the machine and also helps to remove odors that are present.

If a machine is not cleaned regularly, chances are that clothes put through the cycles are going to have a soapy buildup that could irritate skin or have a moldy or mildew smell to them due to the odors that are in the machine. It is recommended that a washing machine be cleaned at least once a month, notes Good Housekeeping. However, those who use their washing machines often may find that they have to clean it more often.
