Restoring LEGO pieces, especially those that have become discolored over time, involves a process of cleaning and brightening using common household items and sunlight.
The primary method for restoring discolored LEGO pieces involves a two-step process: cleaning, followed by a special soaking treatment to address yellowing or discoloration.
Steps to Restore Discolored LEGO Bricks
According to the provided reference, here is the recommended method for bringing discolored LEGO pieces back to their original color:
- Initial Cleaning: First, clean the bricks with soap and water to remove surface dirt and grime. This prepares the pieces for the next step.
- Prepare for Soaking: While wearing safety glasses and latex dishwashing gloves for protection, prepare a container for soaking the discolored pieces.
- Hydrogen Peroxide Soak: Soak discolored Lego pieces in 3% hydrogen peroxide, placed in direct sunlight. The sunlight helps activate the hydrogen peroxide, aiding in the removal of discoloration.
- Ensure Submersion: Make sure all pieces remain completely submerged in the hydrogen peroxide throughout the process.
- Manage Bubbles: Periodically wipe away any bubbles that form on the surface of the bricks. This ensures that the hydrogen peroxide is in direct contact with all surfaces, allowing them to be brightened effectively.
This method is particularly effective for reversing the yellowing process that can occur in some plastics over time, often due to exposure to UV light.
Important Considerations
- Safety First: Always wear appropriate safety gear, such as safety glasses and gloves, when handling hydrogen peroxide.
- Concentration: Use only 3% hydrogen peroxide, which is a common household concentration. Higher concentrations can be dangerous.
- Direct Sunlight: Direct sunlight is crucial for activating the brightening effect of the hydrogen peroxide.
- Patience: The process may take several hours or even days, depending on the severity of the discoloration and the intensity of the sunlight. Check the pieces periodically.
- Rinse Thoroughly: After the soaking process is complete and the desired color is restored, thoroughly rinse the LEGO pieces with clean water to remove any residual hydrogen peroxide.
This technique is a well-known method within the LEGO fan community for rejuvenating aged collections.
