Turn the dials to the largest load size to completely fill your washer. Use the “heavy duty” wash cycle if you can’t manually set the amount of time your washer runs. Set the temperature knob to the hottest wash setting, press start so the drum starts to fill with water, and keep the lid open.[1]If your machine has a “drum clean” cycle, use that setting instead.How often you clean your washing machine depends on how often you use it. Ashley Matuska of Dashing Maids says: “I personally do about 10 or so loads of laundry a week, so I clean my washing machine about once a month. If you use your machine less often, you can clean it every other month. To clean it, run a load on the sanitize setting, or for an older model, set it for a larger load or longer setting with hot water.”Add 4 cups (950 ml) of white vinegar to the drum. Standard white vinegar you have in your kitchen will work fine. As the drum fills with water, pour the vinegar inside your machine.[2]Purchase a container of vinegar to strictly use for cleaning purposes so you don’t have to go to your kitchen every time you want to clean.Pour 1 cup (220 g) of baking soda into the water. Add the baking soda while the water fills the drum so it mixes throughout the machine. The baking soda will react with the vinegar to lift any residue and clean the inside of your machine.[3]Keep a box of baking soda in your laundry room separate from the baking soda you use for cooking. That way, you’ll be able to make the solution when you need it.gitate the water and let it soak for 1 hour. Close the lid on the machine for 1 minute so the cycle can start. This will mix the baking soda, vinegar, and water more thoroughly and will get your cleaning solution throughout the entire drum. After a minute, lift the lid back up to pause the cycle.[4]Some washing machines will lock the lid once the cycle has started. Press the stop or pause button to unlock it and open the lid.lean the bleach, detergent, and fabric softener wells with a toothbrush or a sponge. Dip the bristles of a stiff toothbrush into the water in your machine and scrub all the wells. Focus on areas that have mold or mildew forming on them. Once you’ve scrubbed them, wipe the grime away with a clean dishcloth.[5]If a toothbrush isn’t working, use a stiff-bristled cleaning brush or a sponge with a scrubber side.
Place any removable parts in the water and let them soak for 20 minutes before scrubbing them.
Check the plastic seal around the lid. If you notice dirt and grime, scrub the area with a toothbrush.
Close the machine and let the cycle complete.
 Shut the lid and press start on your machine if the cycle doesn’t immediately resume. Wait until the cycle is completely finished and the drum is drained of the solution.[6]Clean the sides and top of your machine with a damp rag while your cycle is running to make the best use of your time.Wipe the sides and bottom of the drum with a rag after the cycle finishes. Use a clean dishrag to wipe any residue off of the interior of your machine. If needed, dip one end of the rag into a mixture of 3 parts warm water and 1 part vinegar to scrub any trouble areas.[7]If there is a lot of residue, run another cycle with 4  c (950 ml) of vinegar to remove it.
Keep the lid of your washing machine open in between cycles to prevent mildew and let the drum dry out.
Clean your washer every month to keep it fresh.
