Black mold, or Stachybotrys chartarum, is a harmful substance that can grow on plastic under specific conditions. It thrives in moist environments and can cause serious health issues if inhaled. To effectively kill and remove black mold from plastic, several methods can be employed, including the use of diluted bleach, undiluted white vinegar, hot water, and even baking soda. It is important to wear protective gear, such as gloves, safety goggles, and a respirator, to prevent exposure and reduce the risk of health issues when dealing with black mold. Additionally, maintaining clean and dry environments can help prevent mold growth on plastic surfaces.

Bleach solutions
While bleach is effective at removing stains, it may not penetrate the surface of the plastic, and mold may remain. Additionally, dead mold can still cause allergic reactions, so proper removal is crucial. For this reason, a combination of hot water, vinegar, and dish soap is often recommended as a more effective method for removing mold from plastic items. This method also eliminates odors and is safer for sensitive skin and around pets and children.

Vinegar solutions
To use vinegar to kill black mold on plastic, follow these steps:
- Pour undiluted vinegar into a spray bottle.
- Spray the moldy surface on the plastic item, ensuring the entire mold area is covered.
- Let the vinegar remain on the surface for at least one hour. For more severe cases, you can leave it for a longer period, such as overnight.
- After the vinegar has had sufficient contact time, wipe away the mold with a clean, water-moistened towel or sponge. Rinse the sponge frequently and work from top to bottom on vertical surfaces to catch drips.
For everyday cleaning and maintenance, a diluted vinegar solution can be used. Mix equal parts vinegar and water, and apply it to the plastic surface. This will help prevent mold growth and keep your plastic items clean.
If the vinegar alone is not effective in removing the mold, you can try adding other ingredients to enhance its cleaning power. Here are some options:
- Baking Soda: Mix 1 teaspoon of baking soda with 2 cups of water and vinegar, then spray the solution onto the moldy area. Scrub the area with a brush and wipe it clean with paper towels or a sponge.
- Tea Tree Oil: Add 2 teaspoons of tea tree oil to 2 cups of distilled white vinegar in a spray bottle. Spray the solution directly onto the mold and let it penetrate for about an hour before scrubbing or wiping the area clean. Ensure the tea tree oil contains at least 30% Terpinen-4-ol and at least 10-15% Cineole.
- Borax: Mix 1 cup of Borax with 1 gallon of water and vinegar, then spray the solution onto the mold. Brush the area to work the solution into the mold, and then wipe it away with paper towels.
Always remember to dry the cleaned plastic items promptly after rinsing, as moisture can promote mold growth. Additionally, be cautious when using bleach as an alternative to vinegar, as it can discolor plastic and produce toxic fumes.

Hydrogen peroxide
When using hydrogen peroxide to remove mould from plastic, it is important to use a 3% solution to avoid accidental bleaching. First, pour the 3% hydrogen peroxide solution into a spray bottle and spray it onto the mouldy surface until the area is completely covered. Let the solution sit for about 10 minutes or until it stops bubbling. Then, scrub off the mould with a rag or soft brush, starting gently to avoid damaging the surface beneath and slowly scrubbing harder as needed. Finally, wipe the surface dry with a clean cloth or rag and repeat the process if necessary.
It is important to note that while hydrogen peroxide is effective in removing mould, it does not kill it or the harmful mycotoxins that may be present. Mycotoxins are potentially very harmful substances found in some mould varieties and have been associated with diseases such as liver cancer and kidney failure. Therefore, it is crucial to understand the underlying cause of the mould growth and take steps to prevent it from returning. Additionally, always wear gloves when applying hydrogen peroxide as it can cause skin irritation.
Other methods for removing mould from plastic include using diluted bleach, undiluted white vinegar, or a combination of hot water, vinegar, and dish soap. These methods can be effective in removing mould, but it is important to consider the potential drawbacks, such as discolouration with bleach and the need for prolonged soaking with vinegar. Regular cleaning of plastic items, especially water bottles, is essential to prevent mould growth.

Tea tree oil
To make a tea tree oil mold remover, add one teaspoon of tea tree oil to one cup of water (or scale up as necessary) in a spray bottle. Spray the solution over the moldy surface and leave it overnight. You can then wipe the surface with a cloth dipped in vinegar.
It is important to note that tea tree oil can be toxic to small children and animals in large quantities, so be sure to store it in a safe place. Additionally, wear protective gloves when handling tea tree oil to avoid skin irritation.

Dishwasher cleaning
To kill black mold on plastic, you can use a variety of cleaning solutions. Black mold, or Stachybotrys chartarum, can cause serious health issues and spreads quickly through airborne spores, so it is important to take precautions when cleaning. Wear disposable coveralls, rubber gloves, airtight safety goggles, and a face mask or respirator to protect yourself from spores. You can also hang plastic sheeting to close off the affected room from the rest of the house.
Once you have prepared the area, you can start cleaning. Firstly, remove any food, dust, mold, or residue from the plastic surface using a sponge or cloth with antimicrobial soap. Then, create a cleaning solution. You can use diluted bleach (1 cup of bleach per 4 liters of water) or undiluted white vinegar. Bleach is great for removing stains but can discolor plastic, whereas vinegar is perfect for removing odors and is safe for sensitive skin and pets and young children. Never mix ammonia and bleach, as this will create toxic fumes. Soak the plastic in your chosen solution for at least 15 minutes for bleach and 1 hour for vinegar, then rinse and dry promptly to prevent further mold growth.
If there is stubborn residue, add baking soda to the vinegar to create an oxidative reaction that will lift the mold off the plastic, then scrub and rinse again. For plastic water bottles, fill the bottle halfway with equal parts vinegar and water, shake well, and let it settle for a few hours or overnight. Then, empty and rinse the bottle and lid with hot water. Alternatively, you can put dishwasher-safe bottles in the dishwasher, boil them in water, or use a hot water and vinegar solution with dish soap, letting it soak overnight before rinsing with hot soapy water.
To clean your dishwasher, start by removing any leftover food particles or debris from the bottom of the machine and the edges of the door. You can use a sponge or cloth with hot, soapy water to wipe down the surfaces. Next, clean the inside of the dishwasher by running an empty cycle with a specialized cleaning solution or white vinegar. Place a cup of vinegar in a dishwasher-safe container on the upper rack and run a hot water cycle. This will help to remove odors and built-up grime.
Once the cycle is complete, sprinkle baking soda along the bottom of the dishwasher and leave it overnight. The baking soda will help to absorb any remaining odors and grime. In the morning, wipe down the inside of the dishwasher with a damp cloth to remove any residue. Finally, clean the dishwasher filter by removing it from the bottom of the machine and rinsing it under running water. Use a gentle brush or sponge to scrub away any food particles or grease, then replace the filter and close the dishwasher.
To maintain a clean dishwasher, regularly wipe down the inside with a sponge or cloth after each use and remove any food particles from the filter. Run a hot water cycle with vinegar or cleaning solution once a month to prevent odors and built-up grime.
