How to Clean Mildew Out of Your Washing Machine Without Taking it Apart

If your washing machine has started to put off a sour, unpleasant odor, don’t cover it up with scent beads.

Without routine cleaning, your washing machine will begin to host bacteria and can even start to grow mildew, resulting in that bothersome smell.

Not only is this a health risk and a nuisance, but the stench can transfer to your clothes.

Thankfully, there’s an easy way to kill off the bacteria and knock the smell out without taking the machine apart.

What you’ll need:

  • One to two cups of baking soda
  • One to two cups of white vinegar

Step one: Sprinkle the baking soda into the washing machine evenly.

Try to get some on the sides, but most of it should in the bottom as evenly around as you can get it.

Step two: Add the white vinegar. Make sure you have an equal ratio of baking soda to vinegar.

The two chemicals reaction will cause a hissing sound. Don’t be alarmed!

Step three: Do not add any clothes into the washing machine.

Put the washing machine on a “small load” setting with the hottest water setting available.

Step four: Watch the machine carefully to make sure it can handle the spin cycle with nothing in it.

Step five: Repeat until the smell is gone.

Step six: Do this at least once every two weeks or as needed.

Simple as that!

The chemical reaction will kill the bacteria and neutralize the smell.

You can use the washing machine right away after this process.

It will only take as long as one washing cycle will take, and you might have the materials in your kitchen cabinet already.

Hard water can also affect odors in your washing machine plus shorten it’s lifespan. Get your home’s water tested to see if your home and appliances would benefit from a water softener or conditioner.
