Mildew is a type of mould that can be identified by its musty damp odour and white colour. It can be effectively removed from plastic using a variety of solutions, including vinegar, bleach, baking soda, chlorine, borax, and commercial products like MiracleMist. When using vinegar, a solution of equal parts vinegar and water is typically recommended, while bleach should be diluted with water to avoid discolouration. For heavy mildew accumulations, undiluted vinegar or full-strength bleach may be necessary. Commercial products like MiracleMist offer an alternative to homemade solutions, providing effective mildew removal and long-lasting protection against future growth.

What You'll Learn
Bleach solutions can kill mildew on plastic
Bleach solutions can effectively kill mildew on plastic. To make a bleach solution, mix 1/3 cup of Clorox™ Disinfecting Bleach with 1 gallon of water in a bucket. You can also use 1 cup of bleach with 3 gallons of water, especially for larger jobs. Wear gloves and use a sponge or brush to apply the solution to the mildew, allowing it to sit for about 10 minutes. If needed, reapply the solution to keep the surface wet. Finally, rinse the surface with clean water and let it air dry. You can also use a fan to speed up the drying process.
It is important to note that bleach solutions should not be used as a routine practice for mildew cleanup. While it can be effective, it is not always desirable to sterilize an area completely, as a background level of mold spores will remain even after cleaning. Additionally, dead mold may still cause allergic reactions, so it must be removed after killing it with bleach. Always ventilate the area and exhaust the air outdoors when using bleach solutions.
When using bleach solutions, there are some important precautions to keep in mind. Avoid applying bleach in direct sunlight or on unfinished wood, aluminum gutters, windows, marble, non-stainless steel, or porous tile. Always test the solution on an inconspicuous area first to ensure it is safe for the surface. Never mix bleach solutions with other cleaning products containing ammonia, as this can produce toxic fumes.
For smaller items with mildew, such as plastic bottles, a diluted bleach solution can be used. Soak the items in the diluted bleach solution for about 30 minutes, then scrub and rinse them thoroughly. Another option is to use denture cleaning tablets, which can effectively remove mildew and other buildup from plastic items. Simply fill a sink with hot water, add the tablets, and soak the items for at least 20 minutes before rinsing them off.

Vinegar solutions are also effective
To clean mildew on plastic, you can use a mixture of hot water and vinegar. The ratio of vinegar to water can vary, but a common recommendation is one part vinegar to three parts water. Bring the mixture to a boil, then add the plastic items to sanitise for a minute or two. Remove from the heat and let the mixture cool down before rinsing and washing the items again.
Another method is to soak the plastic items in a hot water and vinegar solution overnight. This can be particularly effective for removing mildew from plastic bottle lids and instant pot rings. After soaking, the items should be rinsed and cleaned with hot soapy water.
For light mildew stains on plastic, white vinegar can be diluted with an equal amount of water and sprayed on the affected area. This can also be used as a preventative measure, by misting surfaces to stop mildew from forming.
While vinegar is a useful mildew remover, it may not be suitable for all surfaces. It is important to avoid using vinegar on stone countertops, wooden floors, electronic screens, certain metals, and porous surfaces, as it may cause damage.

Denture cleaning tablets can remove mildew
Mildew can be a stubborn problem, but there are various solutions to tackle it. While bleach is a common go-to, it may not always be suitable or effective, especially if the mildew has penetrated the surface. For plastic items, a diluted vinegar solution is often recommended, but there is another surprising option: denture cleaning tablets.
Denture cleaning tablets are an effective way to remove mildew from plastic items. They contain many of the same ingredients as household cleaners, such as peroxide-based bleach, baking soda, and other cleaning agents. These tablets are designed to clean dentures made of porcelain and acrylic resin, but these ingredients can also be effective on similar household surfaces.
To use denture tablets for removing mildew from plastic, start by filling a sink or container with hot water. The hotter the water, the better, as this will help to activate the tablet and enhance its cleaning power. Place the plastic item in the water, ensuring it is fully submerged. Then, drop in a couple of denture tablets and let them dissolve. The exact amount of time needed for soaking will depend on the severity of the mildew buildup; a good rule of thumb is to soak for at least 20 minutes, but for heavily soiled items, consider leaving them overnight.
After soaking, simply rinse the item with clean water. If desired, you can also scrub the item with a soft-bristled brush and some mild soap to ensure all mildew residue is removed. Allow the item to air dry completely before using it again.
Denture tablets are a convenient and effective way to remove mildew from plastic items. They are also useful for a variety of other cleaning tasks around the home, such as removing stains from coffee mugs and freshening up toothbrushes.

Ammonia and sulfuric acid can be used together
Ammonia is a strong mould killer, often used in commercial mould-cleaning products. It is stronger than vinegar and similar in potency to bleach. However, ammonia should never be mixed with bleach as the combination produces toxic fumes.
Ammonia is an alkaline substance with a pH level between 11 and 13, which is significantly higher than what most moulds can tolerate. To prepare ammonia for mould removal, it should be diluted using a 1:1 ratio of clear ammonia and water.
Sulfuric acid is mentioned in a few sources as a potential mould remover. One source suggests using a solution of ammonia, bleach, and 10% sulfuric acid to eliminate mould on rubber. However, it is unclear whether this solution is suitable for plastic.
While ammonia and sulfuric acid may be effective mould-killing agents individually, there is no clear indication that they should be used together, especially on plastic items. Other products such as vinegar, chlorine bleach, borax, and hydrogen peroxide are recommended for cleaning mildew off plastic items.
