Restore Your Plastic Faucet: Remove Yellowing

how to un-yellow a plastic faucet

White plastic can turn yellow due to exposure to UV rays from the sun or due to the chemicals in the surface of the plastic breaking down. Luckily, there are several ways to restore yellowed plastic to its original white colour. Some common household items that can be used to remove yellow stains from plastic include lemon juice, salt, baking soda, vinegar, and bleach. For more stubborn stains, a peroxide-based cream can be applied and left under sunlight or UV light for 12 to 24 hours.

Using lemon juice and sunlight

Lemon juice and sunlight can be used to effectively remove yellow stains from plastic items. This method is especially useful for cookware, utensils, cutting boards, and small toys.

To start, cut a fresh lemon in half and rub both halves over the affected area of the plastic, ensuring that the lemon juice covers the stains. If the item is too large to be rubbed with a lemon, you can also pour lemon juice into a container and soak the item in it.

After coating the item in lemon juice, take it outside and place it in direct sunlight. The UV rays from the sun will interact with the acid in the lemon juice to whiten the plastic. It is important to ensure that the item is not exposed to harsh, direct sunlight, as the heat may cause damage to sensitive machinery or certain types of plastic.

Let the item sit in the sun for at least three to four hours. If possible, leave it outside for an entire day to ensure that the sun has enough time to remove the yellow stains. Rotate the item every hour or two to ensure that all parts of it receive equal sunlight.

After bringing the item inside, rinse it with warm, soapy water or an all-purpose cleaner to remove any residue. If necessary, use a gentle abrasive with water to remove any remaining stains. Finally, dry the item thoroughly.

Hydrogen peroxide and sunlight

To un-yellow a plastic faucet with hydrogen peroxide and sunlight, follow these steps:

Firstly, purchase some hydrogen peroxide. A pharmacy should be a good place to start. You can also try off-the-shelf cream peroxide products, such as Jerome Russell Bblonde cream peroxide (40 Vol 12%) available on Amazon. For a lower-strength option, you can try a 6% or 9% solution, but it may take longer to work.

Next, put on gloves and safety goggles to protect your skin and eyes. Pour enough hydrogen peroxide into a container to cover the plastic faucet. If your faucet has parts that cannot be soaked, such as electronic components, remove them and set them aside. You can scrub these with a baking soda paste, lemon juice, or a magic eraser.

Now, submerge the plastic faucet in the hydrogen peroxide. If the pieces float, weigh them down with something heavy, such as a stainless steel bolt or screw. Leave the faucet to soak for 12 to 24 hours. If the plastic is still yellow after this time, let it soak for longer.

After soaking, remove the faucet from the hydrogen peroxide and rinse it thoroughly with clean water. Wash the plastic with soap if you have used a harsh cleaner, such as hydrogen peroxide or bleach.

Finally, place the plastic faucet in direct sunlight or under a UV lamp. The UV light will speed up the whitening process by providing the activation energy needed to form reactive oxygen species (ROS) from the hydrogen peroxide. Turn the pieces over after a few hours to ensure even exposure to the sun.

The process can take a few hours to a few days, depending on the severity of the yellowing. Remember to keep an eye on the plastic while it is in the sun, as you do not want the cream to dry out.

Baking soda paste

To clean a yellowed plastic faucet with baking soda paste, start by pouring baking soda into a bowl or container. Slowly add water to create a thick paste, mixing until it has a smooth consistency. Avoid making the paste overly liquid.

Once you have your baking soda paste, moisten the plastic faucet with a bit of water. Then, using a sponge, paper towel, or cloth, rub the paste onto the yellowed area in circular motions. Press hard to ensure the paste gets inside the pores of the plastic.

Let the paste sit for a minimum of 10 minutes to a full day. For best results, apply a little more paste after scrubbing to prevent the mixture from drying out too quickly. This gives the paste time to 'eat' the stains.

Finally, use a clean, lint-free cloth, sponge, or towel to wipe away the paste. Rinse the faucet with warm water and dry it with a towel. Your plastic faucet should now be white and stain-free!

Soaking in bleach

Step 1: Prepare the Bleach Solution

Mix one tablespoon (15 ml) of bleach with one cup (240 ml) of water. It is essential to use this ratio to ensure the solution is effective and safe for the plastic. Put on a pair of gloves to protect your hands from the bleach.

Step 2: Soak the Plastic

Submerge the yellowed plastic faucet in the bleach solution. Ensure that the stained areas are completely covered by the solution. If your faucet has electronic components, remove them before soaking, as you should not submerge electronics in water or bleach.

Step 3: Waiting Period

Let the plastic faucet soak in the solution for 1-2 hours. The bleach will work to remove the yellow stains during this time. For more stubborn stains, you can let the plastic soak overnight.

Step 4: Rinse and Wash

After soaking, remove the plastic from the bleach solution and pour the solution down the sink. Rinse the plastic faucet with soap and water to remove any residual bleach. You can then wash the faucet with mild soap and water to ensure it is thoroughly cleaned.

Additional Tips:

  • Always test the bleach on a small, inconspicuous area of the plastic first to ensure it doesn't cause any damage or discolouration.
  • If you are concerned about the smell of bleach, rinse the plastic item well and let it sit outside in the sun for a couple of days. The sun will help remove any remaining stains and dissipate the bleach odour.
  • For food containers or items that children frequently use, consider using alternative methods like vinegar, baking soda, or lemon juice, as bleach may not be suitable for these purposes.

By following these steps, you can effectively use bleach to remove yellow stains from plastic and restore its original appearance.

Using a magic eraser

Magic Erasers are a versatile cleaning tool that can help remove residue and marks from a variety of surfaces. They are made from melamine resin, a soft and pliable material that hardens into a sturdy plastic. When using a Magic Eraser, it is important to first test it on a small area of the surface you are cleaning, as they can be abrasive and may cause damage or dullness to certain materials, such as high-gloss paint or varnish, stainless steel, and marble or granite countertops.

To use a Magic Eraser to clean a yellowed plastic faucet, follow these steps:

  • Wet the Magic Eraser with water and wring it out.
  • Scrub the plastic faucet with the Magic Eraser.
  • Dip and wring out the eraser as needed, continuing to scrub until the yellowing disappears.
  • Wipe down the faucet with a dry towel.

For tight spots, you can try using Magic Eraser cleaning sheets. You can also use a standard scrub brush first, and then follow up with the Magic Eraser for tougher stains.

Magic Erasers are a great option for cleaning yellowed plastic because they are safe for most bathroom surfaces and can effectively remove water stains, soap scum, and grime. With this method, you can restore your plastic faucet to its original appearance without causing damage or using harsh chemicals.
