Mold can be a persistent pest, especially on plastic items that are frequently exposed to food, humidity, dirt, and dust. To effectively deal with mold on plastic, it is essential to understand the severity of the infestation and the characteristics of the plastic item. While some suggest using diluted bleach solutions, others recommend undiluted white vinegar for removing odors and addressing sensitive skin considerations. For items with stubborn residue, introducing baking soda to the vinegar can facilitate an oxidative reaction that lifts the residue off the plastic. For items with intricate parts, such as water bottles with straws, it is crucial to disassemble them for thorough cleaning and consider replacing individual components if necessary. Additionally, denture cleaning tablets dissolved in hot water can be an efficient method for cleaning mold from plastic items.

What You'll Learn
Soak in a diluted bleach solution
Soaking plastic items in a diluted bleach solution is an effective way to remove mold. However, it's important to note that bleach may not kill mold spores that have penetrated the surface, and it can also discolour plastic with enough concentration. If you choose to use bleach, always ventilate the area and exhaust the air outdoors to avoid inhaling toxic fumes.
To create a diluted bleach solution, combine one cup of bleach with three to four litres of water. You can use a bucket or a sink for this. Before soaking your plastic items, make sure to protect your skin and eyes by wearing gloves and safety goggles. Submerge the moldy plastic items in the bleach solution, ensuring they are fully covered. Let them soak for at least 15 minutes, and up to 30 minutes if needed.
After soaking, remove the items from the bleach solution and scrub them with a brush to remove any remaining mold residue. Rinse the items thoroughly with clean water to remove any bleach residue. Finally, dry the items completely to prevent the mold from returning.
While diluted bleach can be effective for removing surface mold, it may not penetrate deep mold infestations. In some cases, the mold may return worse than before, as the remaining spores can act as compost and fuel new growth. Therefore, it's important to inspect your plastic items thoroughly before and after cleaning to ensure the mold has been completely removed. If the mold persists, it may be necessary to discard the items, especially if they are children's products or come into direct contact with food.

Soak in undiluted white vinegar
Undiluted white vinegar is an effective and non-toxic solution for removing mold from plastic. It is safe for use around pets and children, and it is perfect for removing odors. However, it may not deal with stains as effectively as bleach.
Before using undiluted white vinegar to remove mold, ensure you are wearing protective gear, including non-porous gloves, goggles or safety glasses, and a mask that covers your mouth and nose. If possible, open a window to ventilate the room.
To use undiluted white vinegar to remove mold from plastic, start by pouring the vinegar into a spray bottle. Spray it directly onto the moldy surface and let it sit for at least an hour. Then, using a brush with soft bristles, scrub the moldy surface until the mold comes off. If necessary, use a thicker brush for rougher surfaces. Finally, dry the area completely with a clean rag and dispose of the used rag and brush.
For widespread mold on rugs, carpets, or furniture, simply spraying vinegar may not be sufficient. In these cases, it is recommended to soak the item overnight in a 50/50 mix of warm water and white vinegar. After soaking, rinse the item under warm water and repeat the process as needed until the mold stain fades.

Soak in hydrogen peroxide
Soaking plastic items in hydrogen peroxide is an effective way to remove mold. It is a safer alternative to bleach, which can be harmful to health. Hydrogen peroxide is also inexpensive and readily available in most grocery stores and pharmacies. It is important to wear rubber gloves and appropriate eye protection when handling hydrogen peroxide, as it is a powerful oxidant.
To remove mold from plastic items, create a solution of equal parts hot water and 3% hydrogen peroxide. Submerge the plastic item in the solution and let it soak for at least 15 minutes. For more stubborn mold, a stronger solution of 20-35% hydrogen peroxide can be used. After soaking, scrub the item with a stiff brush and rinse it clean.
Hydrogen peroxide is suitable for use on non-porous materials such as plastic, glass, and metal. It can effectively remove mold stains and inhibit fungal growth on these solid surfaces. However, it is important to note that hydrogen peroxide is not suitable for porous materials like wood and fabric. If mold has penetrated these surfaces, the item should be discarded and safely disposed of according to local guidelines.
In addition to removing mold, hydrogen peroxide can also be used to absorb lingering odors. After treating the moldy surface, place bowls of vinegar, lemon water, or saltwater around the room to neutralize any remaining smells. Leave the bowls for a few days until the odor is gone.
Hydrogen peroxide is a versatile and effective solution for removing mold from plastic items. By following the recommended steps and taking the necessary safety precautions, you can safely restore your plastic items to their original, mold-free condition.

Use denture cleaning tablets
Denture cleaning tablets are an effective way to remove mold from plastic items. They are a safe alternative to harsh cleaning chemicals, especially in homes with children or pets.
To clean mold from plastic using denture tablets, start by filling a sink or container with hot or warm water. The water temperature should be slightly warm, not too hot. Ensure the water level is high enough to completely submerge the moldy plastic item.
Next, drop one or two denture cleaning tablets into the water. You can use any brand of denture tablets, such as Efferdent, which is a common brand name. The tablets will start to fizz and dissolve, creating a sanitizing solution.
Once the tablets have dissolved, place the moldy plastic items into the solution and let them soak. For heavily soiled items, it is recommended to soak them for at least 20 minutes or longer. Lighter mold may only require a few minutes of soaking.
Finally, remove the items from the solution and rinse them thoroughly with water. You can also use a soft brush to scrub away any remaining residue.
Denture cleaning tablets are a convenient and effective way to remove mold from plastic items without damaging the surface. They are safe to use and can be easily found at most grocery or drug stores.

Replace the plastic item
If the plastic item is valuable, expensive, or has sentimental value, it is recommended to consult a specialist in furniture repair, restoration, or conservation. These specialists can advise on the best course of action and may be able to restore the item to its original condition.
In some cases, it may be necessary to replace the plastic item completely. This is especially true for items that come into contact with food, such as cutting boards or children's products. Cutting boards, for example, can develop deep knife grooves that are difficult to clean and can harbour mould and bacteria. Similarly, plastic containers with cracks or scratches may need to be thrown away, as it can be challenging to ensure a thorough cleaning.
For items that are not as heavily affected by mould, there are cleaning methods that can be attempted before considering replacement. These include using diluted bleach, undiluted vinegar, or baking soda to remove mould stains and odours. However, if the mould has affected multiple surfaces in your home or has embedded itself in cracks and crevices, it may be best to call a mould remediation professional. They can provide advanced techniques and equipment to ensure thorough mould removal and prevent its return.
It is important to act promptly when dealing with mould, as exposure to mould spores can cause allergic reactions, asthma attacks, and irritation to the eyes, skin, nose, throat, and lungs. Additionally, proper drying of water-damaged items within 24-48 hours is crucial to prevent mould growth.
