How To Prevent A Moldy Dishwasher

While we recommend regular cleanings of your dishwasher, there are several things you can do in-between cleaning techniques to prevent mold and mildew from making your dishwasher their new home.

Moldy Dishwasher Prevention

One of the first steps that you can take to prevent the build-up of mold and mildew in your dishwasher is to leave the washer door ajar between washing. Doing this allows for airflow in the damp environment, preventing the ideal breeding ground for mold growth.

If you have had a particularly heavy load of extra dirty dishes, run a cleaning cycle with dishwashing detergent in the empty dishwasher. The dishwasher is often treated like a garbage disposal. Dishes that are caked with food and not appropriately rinsed can clog up the dishwasher.

Running an extra load without dishes can help to clean out any leftover food debris and prevent mold growth from starting. Make sure to run a cleaning solution such as vinegar or baking soda through a regular cleaning cycle once per month. Doing this will not only keep your dishwasher clean but prevent mold from taking hold.

The first step to eliminating mold from your dishwasher is to prevent it in the first place by following a few simple steps. Fortunately, there are several different methods to choose from if youve already crossed that line and have a moldy dishwasher.

Now that cleaning the dishwasher can be checked off your to-do list, whats next? How about learning how to make homemade dish soap?

How To Prevent Mould And Mildew On Walls: Our Top 6 Tips

Once youâve dealt with a mildew infestation on your walls, the next step is to try to stop it recurring. Here are your options:

  • Buy a specialised product. An anti-microbial spray, for example, can help prevent the spores from settling again. Anti-mildew paint can also be purchased from most DIY stores.

  • Consider installing an electric de-humidifier in badly affected areas. This is ideal for long-term mould prevention.

  • Look into upgrading your home insulation. Sometimes, but not always, bad insulation is the root of the problem. Walls and ceilings that are properly insulated will be less affected by condensation and therefore mould.

  • The best tips on how to get rid of mould involve cutting out the damp conditions it loves so much:

  • Keep bathrooms, kitchens, and other humid spaces well-ventilated and as dry as possible

  • Spread out shower curtains and towels to dry.

  • Tackle leaks as soon as theyâre discovered to prevent moisture seeping into cavities and under floors.

    Types Of Common Household Mold

    The good news is that not all molds, even the ones that appear to be black in color, are dangerous. There are three categories of common molds found in households that can have health effects:

    • Allergenic molds that can be safely removed by using disinfecting products
    • Pathogenic molds that can be controlled with disinfectants
    • Toxic molds that require professional treatment and disposal of all affected materials

    What has become known as the serious black mold is Stachybotrys chartarum, a colony with a dark green or black slimy surface. Black mold looks like black stains or dots growing in irregular circular patterns. It is most often found in homes or buildings that have been exposed to excessive amounts of water and humidity for an extended period of time, especially after a flood. S. chartarum produces trichothecenes, a type of mycotoxin. Exposure to S. chartarum could potentially lead to a wide range of respiratory health effects, though this has not yet been proven.

    If you discover extensive mold growth, it is a good idea to have a professional mold removal company come in to test and identify the type of mold present. Your local public health department can offer advice on mold testing and refer you to a mold remediation company. The U.S. Department of Environmental Protection recommends the professional removal of mold colonies that cover more than 10 square feet .

    What Kind Of Vinegar Should You Use

    First, save the apple cider vinegar for salad dressing. To clean mold, use regular white distilled vinegar, typically sold with 5% acidity. You can also use cleaning vinegar with 6% acidity. Both are effective at killing mold. Generic brands are as effective as name brands. You can find cleaning vinegar online and at many home improvement, discount and grocery stores.

Black mold is dangerous, and can greatly affect your health if left untreated, so it’s important to remove it as soon as you’re aware of it.

Youre most likely to find black mold in areas of your home that you dont visit as often like the basement, but it can pop up anywhere. Here are a few common moisture sources to look for:

    • Faucets and fixtures. Sink, shower and bathtub faucets and fixtures that are leaking can lead to the growth of black mold over time.
    • Exposed plumbing. Damaged or leaking pipes, especially in warmer temperatures, can often create black mold in areas like basements.
    • Water heaters. A small leak can create black mold in your basement or water heater closet.

    Why There Is Black Mold In Your Dishwasher

    The truth of the matter is that mold spores are always lurking in our homes. They just need to find the right conditions in order to thrive. That is why you can also find them in your shower caulk, where it is damp and humid.

    If black mold is growing in your dishwasher at an alarming rate, one of the following could be the issue:

    Not Cleaning Filters Daily

    It may be news to you that your dishwasher has a filter for food debris. Of course, it makes sense. Think of this filter like the basket drain in your kitchen sink. Its necessary for capturing large food particles. The water used to wash your dishes moves through the filter, making it pretty imperative that the filter is clean.

    In case you needed a little incentive, heres a horror story with a happy ending from Hollister about a customer who had never emptied her filters: The filter was so full of rotting food debris that it was coated in a thick slime that would not allow the water to pass through the filter membrane and circulate through the unit. Cleaning the filter fixed the issue and allowed the water to drain. The homeowner was shown how to clean her unit and never had the issue again.Related: The Single Most Important Thing You Should Do on the 1st of Every Month

  • Remove the racks, rotor and drain strainer and clean them in the sink.
  • Deep-clean the dishwasher with a bottle brush or a toothbrush, paying special attention to rubber and plastic parts.
  • Scrub the drain opening, and scrub the seal around the door, making sure to fold it back to clean the underside.
  • Last, run a sponge up and down the sides to clear up any problems there.
  • After clearing away mold, disinfect the dishwasher. While bleach is a potent disinfectant, its abrasiveness isnt ideal for the dishwasher.

    What Causes Mold In The Dishwasher

    Microbes like mold and bacteria only require a few basic elements to live and thrive: heat, moisture, organic material, and darkness. Your dishwasher checks all of these boxes, so it should not surprise you that having some sort of mold or fungus growing in your dishwasher is actually quite common.

    Why is there mold in the dishwasher?

    The leftover food particles in your dishwasher, in addition to the humid, dark, wet environment, provide an ideal location for these unwanted microbes to live in.

    Now, you might be wondering what about the high temperatures and detergents used in the dishwasher? Dont those kill off unwanted microbes? Unfortunately, the answer is no. Mold can survive the entire dishwasher cycle detergents, hot temperatures and all.

    In addition, most dish-washing detergents contain salt, which yeasts, and black mold thrive on.

    There are plenty of different types of molds, each with their own qualities and preferences. Some will grow around leftover food particles other types prefer rubber parts of the dishwasher or within the drain seal.

    Do You Have Black Mold In Your Dishwasher


    A moldy dishwasher is not only unsightly, but it can also make you sink. According to research, 62% of all dishwashers contain disease-causing fungi, which pose a risk especially to people with compromised immune systems.

    Mold grows in areas with high temperature, damp, humid and dark. All those conditions are available in a dishwasher and that is why such a high number of them have black mold growing in them.

    Mold can grow inside a dishwasher or outside it. If the mold is thriving outside the dishwasher and not actually inside, you most definitely have a leak. This could be the water supply line, water inlet valve, drain pump or the drain hose.

    Black mold inside your dishwasher is a sign that the dishwasher is not drying or draining properly. This could be as a result of a faulty dishwasher vent, bad heating element, clogged drain filter or a blocked/poorly installed drain hose.

    To get rid of mold from your dishwasher, remove the lower dish rack and drain filter and scrub them with warm soap water using a toothbrush. Scrub the door gasket as well. Place a bowl of vinegar in the top dish rack and spray a cup of baking soda at the bottom then run a single cycle on the hottest setting. Leave the door open for the dishwasher to dry.

    Due to how gravity works, water accumulates at the bottom of the dishwasher. That is where you are likely to find a lot of the mold. Mold can also grow in nooks and crevices inside the dishwasher, like the edge of the rubber door gasket.

    Thorough Deep Cleaning Of The Dishwasher

    The following natural dishwasher cleaner is ideal for deep cleaning the dishwasher to remove all traces of food gunk, mold, and mildew. This particular method is a little more time consuming than others, but it does get the job done.

    Begin by filling the kitchen sink with dish soap and hot water. Remove both trays from the dishwasher and place the utensil holder into the soapy water to scrub clean with the sponge. Inspect the dishwasher drain area for clogged food.

    Use a toothpick to remove any food debris or gunk from the sprayer armholes. Pour the vinegar into a spray bottle. Sprinkle baking soda onto the bottom of the washer and then spray the area with the vinegar.

    Use the sponge to scrub the bottom, sides, and inside the door of the washer. Use an old toothbrush to clean around the dishwasher filter, gasket, and other crevices where the sponge wont work.

    After you clean all areas of the dishwasher, replace the racks and utensil holder. Run the washer on its hottest cycle to finish the cleaning process.

    Use this same tactic as one of the best ways to get mildew smell out of a dryer, too. After cleaning, run the dryer on a hot setting for about ten minutes so that it dries completely.

    How To Clean Mold From A Dishwasher

    Now that you know your dishwasher is likely harbouring some unwanted guests, it is time to figure out what to do about it. To get a handle on mold in the dishwasher, you need to focus on doing three things: disinfecting, cleaning, and ventilating.

    DO NOT use bleach. Bleach is often touted as one of the most effective solutions for eliminating mold growth, however, it is not suitable for use in your dishwasher. While it might be great for disinfecting your bathroom or shower, bleach is caustic and might cause negative effects to both your health and the health of your dishwasher.

    Bleach might damage the heating probes within the dishwasher, meaning it will be unable to effectively dry your dishes, leaving them covered in water droplets, and therefore creating a perfect humidity chamber for mold to continue to grow.

    Instead, make use of baking soda and vinegar these ingredients, when added together, create a foamy paste that is both safe for use inside your dishwasher and effective in killing off mold, bacteria, and other potentially harmful microbes. Vinegar kills up to 99% of bacteria and 82% of mold species.

    Mix small amounts of baking soda into a cup of vinegar until the mixture forms a foamy paste. Using a dish scrubbing brush, scrub the dishwasher, paying close attention to the small cracks, crevices, and harder-to-reach areas inside of the dishwasher. You can also use a toothbrush to get into smaller areas more effectively.
