To properly clean your washing machine with bleach, set the washer temperature to the hottest possible setting and then let the tub fill with water. Add 1 quart of bleach directly into the washing machine tub and pause the washing machine. Let the bleach water sit for an hour before starting the washer back up.
To clean your washing machine properly, you must set it to the longest, hottest setting. If you have a self-cleaning cycle, then use that. Add a cleaning agent to the washing machine and switch it on. The cleaning cycle can last up to 4 hours, so you have time to give the outside a clean too.
Manufacturers recommend that you clean your washing machine at least once a month or every 30 cycles. Depending on how often you use your washing machine, you can extend this to once every 2 months, so long as you allow the washing machine drum to dry out with the door open after each wash.
To properly clean your washing machine with baking soda, you will first need to set the washing machine to the hottest water setting and the largest load. Once the tub has filled, add 2 cups of baking soda to the water and then close the lid. Then let the washer complete a full cycle.
