Bleach is a powerful disinfectant that is commonly used for cleaning bathrooms. However, using bleach on plastic toilet covers can lead to undesirable results. Bleach can cause plastic toilet covers to turn yellow, and these bleach stains are challenging to remove. To restore the appearance of a discoloured toilet cover, various alternative cleaning methods and products can be explored, such as baking soda, white vinegar, lemon juice, hydrogen peroxide, or specialised cleaning products. In some cases, painting the toilet cover or replacing it entirely may be necessary to achieve the desired outcome.

What You'll Learn

Bleach alternatives: baking soda, white vinegar, lemon juice, or hydrogen peroxide
Baking Soda
Create a paste by mixing baking soda with water. Apply the paste to the toilet cover and let it sit for a day. Then, use a sponge or paper towel to scrub the paste into the stain, pressing hard to get the paste inside the pores of the plastic. Rinse the paste off with clean water.
White Vinegar
Pour white vinegar around the toilet bowl and seat. Let it sit for 15 minutes, then scrub the toilet thoroughly in circular motions. Let it sit for another 5-10 minutes before rinsing off the vinegar and drying the toilet with a paper towel.
Lemon Juice
Cut a lemon in half and rub it on the toilet cover until the stain is covered in juice. Place the toilet cover outside and let it sit in the sun for a few hours. Finally, rinse the lemon juice off with water.
Hydrogen Peroxide
Fill a plastic bag or container with enough hydrogen peroxide to cover the toilet cover. Place the toilet cover in the container and set it out in direct sunlight. Wait 3-4 hours, then rinse the hydrogen peroxide off with clean water.

Soak plastic in diluted bleach for 1-2 hours
While bleach is a powerful disinfectant, it is not recommended for cleaning plastic toilet covers as it can cause discolouration and corrosion. If you have already used bleach on your plastic toilet cover and are looking to restore its original colour, there are alternative methods you can try. One option is to soak the plastic cover in a diluted bleach solution for 1-2 hours. However, it is important to exercise caution as bleach is corrosive and can be toxic if not handled properly. Make sure to wear protective gear, such as gloves and eye protection, and ensure the area is well-ventilated.
To create the diluted bleach solution, mix a small amount of bleach with water. Always add bleach to water, not the other way around, to avoid splashing concentrated bleach on yourself or nearby surfaces. The recommended ratio is one part bleach to ten parts water. Be sure to prepare the solution in a well-ventilated area and avoid inhaling the fumes.
Completely submerge the plastic toilet cover in the diluted bleach solution. Ensure that all the areas you want to treat are covered by the solution. Let the cover soak for 1-2 hours, periodically checking to ensure that all the discoloured areas remain submerged. You may need to weigh down the cover or stir it occasionally to ensure even exposure to the solution.
After soaking, remove the plastic cover from the solution and rinse it thoroughly with clean water to remove any residual bleach. Allow the cover to air dry completely before reattaching it to the toilet. Remember to dispose of the diluted bleach solution properly and avoid pouring it directly into natural water sources or drains, as it can be harmful to aquatic life.
If you are hesitant to use bleach, there are alternative methods to remove stains from plastic toilet covers. One option is to use natural products like baking soda, vinegar, or lemon juice. Create a paste by mixing baking soda with water, apply it to the stained areas, let it sit for 10 minutes, then scrub it with a damp cloth in a circular motion until the stains disappear. Rinse with clean water and dry with a clean towel. Alternatively, you can try using commercial products like Elbow Grease or The Pink Stuff Paste, which have been recommended by cleaning enthusiasts.

Use a magic eraser for electronics
Bleach is a corrosive substance that can cause discolouration to plastic and other materials. While bleach is a powerful disinfectant, it is not recommended for cleaning a plastic toilet cover as it can cause permanent yellow stains.
To clean a yellow plastic toilet cover, you can use a magic eraser, which is a popular cleaning tool that can be used to scrub away tough stains and grime. Here is a step-by-step guide on how to use a magic eraser to clean your yellow plastic toilet cover:
Step 1: Understand the Magic Eraser
Magic Erasers, also known as Mr. Clean's Magic Erasers, are not your typical sponges. They are made of melamine-formaldehyde condensate, which creates an effective cleaner, thermal insulator, and soundproofing material. This unique composition enables the Magic Eraser to tackle even the toughest grime and dirt that other cleaners may struggle with.
Step 2: Prepare the Magic Eraser
Magic Erasers can be used dry, but for optimal results, it is recommended to add water to the sponge. This helps the Magic Eraser absorb dirt more effectively. Squeeze the sponge to ensure it is damp but not dripping wet.
Step 3: Test on a Small Area
Before you begin scrubbing your toilet cover, it is important to test the Magic Eraser on a small, inconspicuous area of the plastic surface. This is because the Magic Eraser is slightly abrasive, and while it is great for removing tough stains, it may also dull or scratch delicate or shiny surfaces. Choose a small section of the plastic toilet cover that is usually hidden or not easily noticeable. Gently rub the Magic Eraser on this area in a circular motion for a few seconds and then inspect the results. If there is no damage or discolouration, you can proceed to the next step.
Step 4: Scrub the Stains
Now that you have confirmed the Magic Eraser is safe to use on your plastic toilet cover, it's time to tackle those yellow stains. Apply gentle pressure and scrub the stained areas with the Magic Eraser using a circular motion. You may need to spend more time on particularly stubborn stains, applying a bit more pressure as needed.
Step 5: Rinse and Dry
Once you have removed the stains, rinse the toilet cover with clean water to remove any residue from the Magic Eraser. Dry the surface with a clean cloth or towel.
Step 6: Maintain Regular Cleaning
To prevent the build-up of stains and discolouration, it is important to maintain a regular cleaning routine. This may include weekly deep cleaning with antibacterial cleaners and a soft cloth or sponge to keep your toilet cover looking its best.
By following these steps and using a Magic Eraser for electronics, you can effectively remove yellow stains from your plastic toilet cover without resorting to harsh chemicals like bleach. Remember to always test on a small area first and avoid using excessive pressure or scrubbing speed to prevent any potential damage to the plastic surface.

Elbow Grease or The Pink Stuff: all-purpose degreasers
Unfortunately, if your plastic toilet cover has been stained yellow by bleach, there is little hope of reversing the damage. Bleach is corrosive, and when it reacts with the surface of a toilet seat, it can cause discolouration. To restore your toilet seat to its original white finish, you may need to paint it.
If you're looking for a powerful degreaser to help tackle tough grease and oil stains on your plastic toilet cover, you could consider Elbow Grease or The Pink Stuff. Both products are all-purpose degreasers that can be used on a variety of surfaces, including plastics.
Elbow Grease All-Purpose Degreaser is a solvent-free formula that is gentle yet effective. It can be used on delicate fabrics and coloured materials, as well as tougher surfaces like vehicle parts and metal. Elbow Grease is known for its pleasant lemon scent and is available in a 500ml spray bottle. It is important to note that Elbow Grease is not suitable for wood or transparent polycarbonates, and it can cause skin irritation and eye damage, so caution should be exercised during use.
The Pink Stuff Miracle Multi-Purpose Cleaner is designed for use on hard surfaces. It comes in a spray bottle and should be applied directly to the surface, left for a few seconds, and then wiped away with a damp cloth. It is important to test this product on an inconspicuous area first, as it may not be suitable for certain surfaces, such as waxed or painted wood. The Pink Stuff also contains Benzisothiazolinone, which may cause an allergic reaction, so individuals with sensitive skin should wear gloves when using this product.
When deciding between Elbow Grease and The Pink Stuff, consider your specific needs and the type of surface you will be cleaning. Both products are effective degreasers, but Elbow Grease may be more suitable for fabrics and delicate surfaces, while The Pink Stuff is formulated for hard surfaces. Always read the product labels and instructions carefully before use, and take the necessary precautions to protect your skin and eyes.
To maintain the appearance of your plastic toilet cover, it is recommended to clean it regularly with gentle cleansers like soap and water or natural products like vinegar and lemon juice. These methods can help remove stains and keep your toilet cover looking polished without causing discolouration or irritation.

Paint over the stained area
If you want to paint over the stained area of your plastic toilet cover, there are a few steps you should follow. Firstly, it is important to clean the toilet seat thoroughly to remove any leftover bleach. Removing the seat from the toilet will make this process easier. Once the seat is dry, use fine-grit sandpaper on the stained areas to create a gritty texture that will help the paint adhere better. After sanding, give the seat a quick clean with water to remove any dust.
Now, you can apply a spray primer to the area. Ensure that the primer is suitable for the material of your toilet seat. Hold the can about 8 inches away from the surface and coat the area evenly. Allow the primer to dry for about 1-2 hours, and then flip the seat over and prime the other side.
After the primer is completely dry, you can start painting. Use a spray paint that is specifically designed for toilet seats, capable of withstanding weight, friction, and moisture. Follow the directions on the spray paint can, and shake it well before use. Spray a light coating from a distance of about 6-10 inches away, and let it dry. It is important not to spray too closely or to overspray, as this can cause drips and bubbles.
Repeat the spraying process as many times as needed, allowing sufficient drying time between each coating. Once you have achieved the desired results and the paint is completely dry, you can reattach the toilet seat. Your toilet seat will now look as good as new, and the stained area will be hidden.
