Yellowing plastic is a common problem that can make your belongings look old and unsightly. Over time, the plastic can become brittle and more susceptible to breaking. However, there are a few simple steps you can take to get the yellowing out of plastic and restore it to its original appearance.
One of the easiest ways to remove yellowing from plastic is to use a household cleaner. Regular household cleaners are designed to remove dirt, grime, and stains from surfaces, and many of them can be effective at removing yellowing from plastic as well. To use a household cleaner to remove yellowing from plastic, simply apply the cleaner to a clean cloth and wipe down the plastic surface. Be sure to rinse the surface thoroughly with water after cleaning to remove any residual cleaner. You may need to repeat the process several times to completely remove the yellowing.
If a household cleaner is not effective at removing the yellowing from your plastic, you may need to use a stronger solution. Hydrogen peroxide is a bleaching agent that can be used to whiten plastic. To use hydrogen peroxide to remove yellowing from plastic, mix equal parts hydrogen peroxide and water in a bowl. Apply the solution to a clean cloth and wipe down the plastic surface. Be sure to rinse the surface thoroughly with water after cleaning to remove any residual hydrogen peroxide. You may need to repeat the process several times to completely remove the yellowing.
Identify the Type of Plastic
Before attempting to remove yellowing from plastic, it’s crucial to identify the type of plastic you are dealing with. The type of plastic will determine the most appropriate cleaning method and the success rate of your efforts.
Here’s a guide to help you identify the type of plastic:
- Examine the recycling symbol: Most plastic items have a recycling symbol embossed on them. The symbol consists of a triangle with a number inside. The number indicates the type of plastic, as follows:
- Consider the texture and flexibility: Different types of plastic have distinct textures and flexibility. For example, PET is a hard and rigid plastic, while LDPE is soft and flexible.
- Test its resistance to heat: Some plastics melt at lower temperatures than others. To test this, hold a lighter or heat source near the plastic. If the plastic melts or becomes soft, it is probably a low-temperature plastic such as PVC or LDPE.
Use a Mild Dishwashing Liquid Solution
Commercial plastic cleaning solutions can be harsh and potentially damage your plastic items. Instead, opt for a mild dishwashing liquid, which is gentle enough for most plastics while still being effective at removing yellowing. Mix a few drops of dishwashing liquid with warm water in a bowl or basin, creating a mild cleaning solution.
Steps for Using a Mild Dishwashing Liquid Solution:
Step Instructions 1 Dip a soft, clean cloth or sponge into the cleaning solution. 2 Gently rub the yellowed areas of the plastic in circular motions. 3 Rinse the plastic thoroughly with clean water to remove any remaining cleaning solution. For stubborn yellowing, allow the cleaning solution to sit on the affected areas for 10-15 minutes before rubbing. Rinse thoroughly once the yellowing has diminished.
Try a Hydrogen Peroxide Solution
Hydrogen peroxide is a powerful bleaching agent that can help to remove yellowing from plastic. To use this method, you will need:
- Hydrogen peroxide (3%)
- Spray bottle
- Clean cloth
Instructions:
- Mix equal parts hydrogen peroxide and water in the spray bottle.
- Spray the solution onto the yellowed plastic and let it sit for 15-30 minutes.
- Wipe away the solution with a clean cloth.
Tips
- For stubborn yellowing, you may need to repeat the process several times.
- Do not use hydrogen peroxide on painted or dyed plastic, as it may damage the finish.
- Hydrogen peroxide can be harmful if ingested, so keep it out of reach of children and pets.
Material Solution Plastic Hydrogen peroxide (3%) Painted or dyed plastic Not recommended Apply a Baking Soda Paste
Baking soda is a powerful natural cleaning agent that can help remove yellowing from plastic. To use baking soda, create a paste by mixing one part baking soda with three parts water. Apply the paste to the yellowed plastic and let it sit for at least 30 minutes. Once the paste has dried, use a damp cloth to wipe away the residue. For particularly stubborn stains, you may need to repeat the process.
Detailed Instructions
1. Gather your materials. You will need:
- Baking soda
- Water
- Damp cloth
2. Create the baking soda paste. In a small bowl, mix one part baking soda with three parts water. The paste should be thick and creamy.
3. Apply the paste to the yellowed plastic. Use a spoon or your fingers to apply the paste to the yellowed plastic. Be sure to cover the entire surface of the plastic.
4. Let the paste sit. Allow the paste to sit on the plastic for at least 30 minutes. This will give the baking soda time to work its magic.
5. Wipe away the residue. Once the paste has dried, use a damp cloth to wipe away the residue. Be sure to rinse the cloth thoroughly after each use.
6. Repeat as necessary. For particularly stubborn stains, you may need to repeat the process. Simply reapply the baking soda paste and let it sit for another 30 minutes.
Tips:
* If you are using baking soda to clean a large plastic item, you may want to make a larger batch of paste.
* You can also use a toothbrush to gently scrub the yellowed plastic.
* Be sure to rinse the plastic thoroughly after cleaning.Use a Commercial Plastic De-Yellowing Kit
Prep the Plastic
Start by cleaning the plastic with soap and water to remove any dirt or debris. Dry it thoroughly with a clean cloth. If the plastic is particularly dirty, you may need to use a degreaser to remove any oils or grease.
Apply the De-Yellowing Solution
Apply the de-yellowing solution to the plastic according to the manufacturer’s instructions. Most solutions will require you to apply a generous amount to the surface of the plastic. Use a clean cloth or brush to work the solution into the plastic.
Let the Solution Sit
Allow the solution to sit on the plastic for the amount of time specified in the instructions. This will give the solution time to penetrate the plastic and break down the yellowing agents.
Rinse the Plastic
Once the solution has had time to sit, rinse the plastic thoroughly with clean water. Use a clean cloth to dry the plastic. The yellowing should now be significantly reduced or eliminated.
Repeat if Necessary
If the yellowing is still not completely gone, you may need to repeat the process. Some plastics may require multiple applications of the de-yellowing solution to achieve the desired results.
