Wipe out bacteria: Hot water (between 140ºF and 150°F) and bleach is the only way to kill germs. Washing a load of whites in hot water and chlorine bleach sanitizes the machine.
Take extra precaution: Once a month, run an empty load with hot water and bleach to sanitize the basin and wipe out any lingering germs.
Clean: With each load of whites
