Can polypropylene outdoor flower pots be sterilized using UV-C light?
Polypropylene outdoor flower pots are popular for their durability and lightweight properties, but can they be sterilized using UV-C light? UV-C light is known for its germicidal effects, effectively killing bacteria, viruses, and mold. However, polypropylene is generally resistant to UV degradation, making it a suitable material for brief UV-C exposure. To sterilize, ensure the pots are clean and dry, then expose them to UV-C light for 10-15 minutes per side. Avoid prolonged exposure, as it may weaken the plastic over time. This method is a chemical-free way to maintain hygiene in your garden planters. Always follow safety guidelines when using UV-C devices to protect your skin and eyes.
