Clean plastic items regularly
Regular cleaning of plastic items is essential to prevent mould buildup. This is especially important for plastic items that come into direct contact with food, such as water bottles and food containers. Mould thrives in moist environments, so it is crucial to ensure that these items are thoroughly cleaned and dried after each use.
For plastic water bottles, it is recommended to clean them at least once a day to prevent mould formation. If mould does appear, it can be removed by filling the bottle halfway with distilled white vinegar and water in equal proportions. Shake the bottle well, let it settle for a few hours or overnight, then rinse thoroughly with hot water. Alternatively, a 3% hydrogen peroxide solution can be used instead of vinegar.
For plastic food containers, it is important to clean them promptly after use to prevent mould growth. If mould does occur, it can be removed by washing the container with dish soap and hot water, then rinsing and drying it thoroughly. Soaking the container in a solution of vinegar or bleach can also be effective in removing mould. However, it is important to wear rubber gloves and ensure proper ventilation during the cleaning process.
In addition to regular cleaning, proper storage of plastic items can help prevent mould growth. Avoid storing plastic items in places with poor air circulation, such as sealed bags or containers. Ensure that the storage area is clean and dry to minimise the risk of mould.
By maintaining a regular cleaning routine and proper storage practices, you can effectively prevent mould from growing on your plastic items.

Use natural disinfectants like vinegar
Vinegar is an effective natural disinfectant that can be used to keep mould off plastic. It has antifungal and antibacterial properties due to its acetic acid content, which can disrupt the growth of fungi and microorganisms. Here are some steps to effectively use vinegar to prevent and remove mould on plastic items:
Choosing the Right Vinegar
Distilled white vinegar is ideal for cleaning mould off plastic. It typically contains around 5 to 8 percent acetic acid, which is effective at disrupting mould growth.
Preparing the Vinegar Solution
Mix equal parts distilled white vinegar and water in a container. You can also add a few drops of dish soap to enhance the cleaning solution. This mixture will create an effective cleaning solution that is safe for plastic surfaces.
Soaking the Plastic Items
Fill your plastic items, such as water bottles, with the vinegar solution. Alternatively, if you are cleaning plastic surfaces or items that cannot be filled, soak a cloth or sponge in the vinegar solution and apply it directly to the mouldy areas. Ensure that all mouldy areas are thoroughly saturated.
Soaking Duration
Let the plastic items or surfaces soaked in the vinegar solution sit for at least an hour. For more stubborn mould, you can let it soak overnight. The acetic acid in the vinegar will help loosen and break down the mould during this time.
Scrubbing and Rinsing
After soaking, use a soft-bristled brush to scrub the mouldy areas gently. If the surface is rougher, you may need to use a thicker brush. Rinse the plastic items or surfaces thoroughly with warm or hot water to remove any remaining vinegar solution and mould residue.
Drying
Proper drying is crucial to prevent mould from returning. Use a clean cloth or rag to dry the cleaned items or surfaces completely. Ensure that all areas are thoroughly dried, as moisture can encourage further mould growth.
By following these steps and regularly cleaning your plastic items with vinegar, you can effectively prevent and remove mould growth. Vinegar is a safe and natural alternative to harsh chemical cleaners, making it a cost-effective and environmentally friendly option for mould prevention and removal.

Bleach as an alternative to vinegar
Bleach and vinegar are both commonly used to remove mold from plastic surfaces. However, bleach may not be the best option for removing mold, as it only removes the colour from the mold, allowing it to continue growing and penetrating the surface. On the other hand, vinegar is effective at preventing mold growth and removing some common household molds.
When using vinegar to remove mold, it is important to first address the moisture problem that caused the mold growth. Undiluted white vinegar with at least 5% acetic acid can be sprayed directly onto the moldy surface and left for at least an hour before scrubbing. This method can be effective for removing mold from plastic surfaces. However, vinegar is not effective against all types of mold, and it may not be suitable for porous surfaces where mold roots can penetrate deeply. In such cases, replacing the affected plastic item may be necessary.
As an alternative to vinegar, bleach can be used to remove mold from plastic surfaces. It is recommended to soak the plastic item in a bleach solution for at least 15 minutes before scrubbing. Bleach can be effective in removing surface mold, but it may not penetrate deep into the plastic, allowing mold to regrow. Additionally, bleach can be toxic and harmful to health, so proper ventilation is crucial when using it.
While bleach and vinegar can be used as DIY solutions for mold removal, they have limitations and may not be effective for all situations. For large mold infestations or mold growth inside silicone or porous plastic, professional mold remediation services are recommended. These professionals have the expertise and equipment to thoroughly remove mold and prevent its recurrence.

Use antimicrobial agents to prevent mold
While plastic is a highly durable and versatile material, it is not immune to mould growth under the right conditions. To prevent mould from growing on plastic, you can use antimicrobial agents. "Antimicrobial," means "against microscopic life forms". In other words, antimicrobials are substances designed to destroy or inhibit the growth of microorganisms, including mould, bacteria, and viruses.
One example of an antimicrobial agent is MPI (Mould Prevention Innovations) Antimicrobial, which is designed to inhibit the growth of damaging microbes such as bacteria, mould, mildew, fungus, and algae. MPI Antimicrobial is environmentally safe, permanent, and does not emit volatile organic compounds (VOCs). It can be applied to most finished or unfinished surfaces, including wood, flooring, concrete, drywall, and fabrics.
Another option for preventing mould on plastic is to use hydrogen peroxide, which is effective at getting rid of any harmful microorganisms because it eats away at any living tissue. When using hydrogen peroxide to clean mould off plastic, pour a 3% concentrated solution into your plastic item and let it sit for a few minutes before rinsing.
It is important to note that antimicrobials are not a simple, all-encompassing solution to mould prevention. Their use requires additional expertise to ensure they are applied correctly and effectively. Reputable companies will only communicate information supported by product labels and avoid making unsubstantiated claims. Always follow the specific instructions on the label of the antimicrobial product you are using, including the method of application (spraying, fogging, or wiping) and the required dwell time.
