Maintenance
To ensure the longevity and cleanliness of your LEGO set, follow these simple maintenance guidelines:
- Cleaning: Use a soft brush or a damp cloth with mild soap to gently clean LEGO bricks. Avoid harsh chemicals or abrasive materials.
- Storage: Store your LEGO set in a cool, dry place away from direct sunlight to prevent discoloration and damage. Keep small pieces in a container to avoid loss.
- Handling: Handle the assembled models with care, especially when moving or posing them, to prevent pieces from detaching.
Troubleshooting
If you encounter any issues during assembly or play, consider the following:
- Missing Pieces: Double-check all bags and the building area. If a piece is genuinely missing, contact LEGO Customer Service for replacements.
