Restore Yellowed Shoes: Bring Back White Plastic Trim

how to unyellow plastic on shoes

Yellowing of plastic shoes is a common problem, often caused by oxidation, which is the process of a substance losing electrons, usually when it comes into contact with oxygen. This process is accelerated by heat and moisture, and the result is a change in the molecular structure of the plastic, causing it to absorb and reflect light differently, which we perceive as a yellow colour. While some sources suggest that this process cannot be reversed, there are several methods that can be used to reduce the yellowing of plastic shoes.

Characteristics Values
Cause of yellowing Oxidation, exposure to sun, heat, and moisture
Prevention Avoid wearing shoes on hot, sunny days, or storing them in warm, damp places
Solutions Hydrogen peroxide, UV light, vinegar, ammonia-based solvents, Angelus Sole Bright
Considerations Test on a small area first, avoid overexposure to UV rays, incorporate regular cleaning

Soak shoes in hydrogen peroxide and water

So, your favourite white sneakers have started to turn yellow? It's a common problem and can be incredibly frustrating. There are a few methods you can try to restore your shoes to their former glory, but one popular option is to soak them in a solution of hydrogen peroxide and water.

Firstly, you need to create the solution. In a container, mix one cup of hydrogen peroxide with one cup of water. You can adjust the measurements depending on the intensity of the yellow stains and how much liquid you need to submerge your shoes.

Next, submerge your shoes in the solution. You may want to use an old toothbrush or a soft-bristled brush to gently scrub the solution onto the shoes, ensuring the liquid penetrates any grooves or textures on the shoe's surface. Leave the shoes to soak for around 15-30 minutes.

After the allotted time, remove your shoes from the solution and rinse them thoroughly with clean water. You can then leave your shoes to air dry. It is recommended to avoid drying them in direct sunlight, as this can damage the material. Instead, opt for a well-ventilated room.

For heavily yellowed shoes, you may need to repeat this process several times to achieve the desired results. Make sure the shoes are completely dry between treatments.

This method of using hydrogen peroxide and water is an effective way to remove yellow stains from shoes without resorting to harsh chemicals like bleach. It is always recommended to test any cleaning product on a small, inconspicuous area of the shoe first, to ensure it does not cause any discolouration or damage to the material.

Dry shoes with a cloth

Drying your shoes with a cloth is a great way to avoid damage from a dryer. Firstly, you'll want to clean your shoes with a mild detergent solution in warm water and use a dry brush to gently scrub away debris. You can also use a damp cloth or an old toothbrush with a bit of dish soap to wipe away any mud or dirt. If your shoes are made of leather, you should avoid using a dryer as it could damage the material.

Once your shoes are clean, remove the insoles and laces and set them out to dry separately. You can place them near a fan to speed up the process. If your shoes are only slightly damp, you can dry them with a cloth by patting the soles and the interior until they are no longer wet. However, if your shoes are soaked, you'll need to use a different method in addition to patting them down with a cloth.

To dry the body of the shoe, you can stuff the inside with rags, t-shirts, or socks to absorb moisture. Make sure to push the cloth all the way into the toe of the shoe and add enough material to fill the shoe completely. You can also wrap the outside of the shoe with a dry cloth or towel, securing it with rubber bands. Place the wrapped shoes in a well-ventilated area, such as a countertop with a fan or an open window. Check and replace the cloths every 2-3 hours until the shoes are completely dry.

Using a hairdryer is another option for drying your shoes with a cloth. Set your hairdryer to medium heat and gently blow-dry all sections of the shoe, being careful not to hold the dryer in one spot for more than 2 minutes to avoid melting or warping the material. You can also use a cloth to wipe down your shoes after drying them to remove any remaining moisture.

Avoid overexposure to UV rays

To avoid overexposure to UV rays when attempting to remove yellowing from shoes, it is important to understand the role of UV rays in the process and how to mitigate potential risks.

UV rays, or ultraviolet radiation, from the sun can have various effects on the human body. While moderate exposure to UV rays is necessary for vitamin D production, overexposure can lead to several adverse health issues. The sun's UV rays can reach and impact the DNA within skin cells, causing them to malfunction and potentially leading to skin cancer. This risk is heightened during peak UV radiation hours, typically between 10 a.m. and 4 p.m., when the sun's rays are at their strongest.

To avoid overexposure to UV rays, it is recommended to follow these guidelines:

  • Limit direct sun exposure during peak hours. Stay in the shade or seek indoor spaces whenever possible during this time.
  • Wear protective clothing. Choose tightly woven fabrics or clothing with a UV protection factor (UPF). Cover as much skin as possible, including wearing long sleeves, pants, and a wide-brimmed hat.
  • Use sunscreen. Apply a broad-spectrum, water-resistant sunscreen with an SPF of at least 30 generously to all exposed skin. Reapply every two hours and after swimming or sweating.
  • Protect your eyes. Wear sunglasses that offer 99 to 100 percent UV protection to shield your eyes from harmful rays.
  • Be cautious near reflective surfaces. Water, snow, and sand can reflect and intensify UV rays, increasing your exposure. Take extra precautions when in these environments.
  • Maintain regular skin checks. Familiarize yourself with existing skin growths and perform self-exams to notice any changes or new growths.

By following these precautions, you can effectively avoid overexposure to UV rays while treating yellowing on shoes and protect your health in the process.

Use ammonia-based solvents

If you want to remove the yellowing from plastic shoes, one method is to use an ammonia-based solvent. This is a chemical process, and one such solvent is Windex, which is used by conservators to clean vinyl.

To use this method, you will need to get a Q-tip and soak it in Windex. Then, carefully rub the Q-tip over the yellowed areas of your plastic shoes. This method is especially useful for transparent plastic shoes, as it will not leave any residue or cloudiness.

It is important to note that this method may not work for all types of plastic shoes, and it is always a good idea to test it on a small, inconspicuous area first to ensure that it does not cause any damage or discolouration. Additionally, be sure to follow any safety instructions on the product label, such as wearing gloves or working in a well-ventilated area.

Using an ammonia-based solvent is a simple and effective way to remove yellowing from plastic shoes, but it is always a good idea to consult a professional conservator or shoe repair specialist if you have any concerns or questions about the process. They may have additional tips or tricks to ensure the process is safe and effective for your particular type of shoe.

Avoid chemical cleaners

If you want to avoid using chemical cleaners on your shoes, there are several natural alternatives you can try. One option is to soak your shoes in a solution of one part lemon juice and two parts water. After soaking for about 30 minutes, rinse the shoes with clean water and allow them to air dry. Lemon juice is a safe and gentle way to remove yellow stains from plastic, and it will leave your shoes smelling fresh.

Another natural method is to use a paste made from baking soda and water. Apply the paste to the affected areas of your shoes and scrub gently with a toothbrush. You can also try mixing baking soda with vinegar to form a paste, which works well for white canvas shoes that are lightly soiled. Leave the paste on until it dries, then brush it off. Baking soda can also be used to clean the insides of shoes, which may be a source of yellowing due to contact with feet.

For small toys and items, you can soak them in lemon juice for an hour in the sun, then brush them off and rinse and dry. Alternatively, you can use white vinegar, which is a safe alternative to harsh cleaners. Mix one part vinegar with one part water, and let the plastic sit in the solution for a couple of hours before rinsing and drying.

If you are looking for a more intensive cleaning method that does not involve chemicals, you can try using a Magic Eraser. Wet the Magic Eraser with water and scrub the yellowed plastic. Dip and wring out the eraser as needed, and continue to scrub until the stain is removed.

It is important to note that some of these natural methods may require more elbow grease than chemical cleaners, and they may not be effective for severe discolouration. However, they are safe alternatives that can help remove yellow stains from your shoes without the use of harsh chemicals.
