### **Chapter 4: Advanced Whitening Techniques**
For more stubborn discoloration, you may need to use advanced techniques. These methods are perfect for plastic chairs that have been exposed to heavy sunlight or have been neglected for an extended period.
#### **4.1 Sun-Exposure Method**
Believe it or not, the sun can be used to help restore the whiteness of plastic. This method works best when combined with hydrogen peroxide.
1. **Apply Hydrogen Peroxide**: Apply hydrogen peroxide directly to the yellowed areas of your plastic chair, as described earlier.
2. **Place the Chairs in the Sun**: After applying the hydrogen peroxide, place your chairs outside in direct sunlight. The heat from the sun will help activate the hydrogen peroxide, allowing it to whiten the plastic.
3. **Let the Process Work**: Leave the chairs in the sun for several hours (or even a full day), checking periodically to see if the yellowing is lifting.
4. **Rinse and Dry**: After a few hours, rinse off the hydrogen peroxide and allow the chairs to dry.
#### **4.2 Using Plastic Restorer**
If you’re looking for a more commercial solution, plastic restorers are available that can restore both color and shine to plastic furniture.
1. **Choose a Plastic Restorer**: Select a high-quality plastic restorer from your local home improvement store or online. Make sure to read reviews and check product recommendations for whitening plastic.
2. **Apply the Restorer**: Follow the instructions on the product. Generally, you’ll apply the restorer using a clean cloth and rub it into the plastic in circular motions.
3. **Buff to Shine**: After applying the restorer, use a microfiber cloth to buff the surface and bring out a glossy finish.
