To address a leaking teapot, first inspect the lid for gaps or cracks. If present, apply a silicone sealant or replace the lid. Next, check the spout for a loose washer or damaged seal. Tightening the washer or using a rubber gasket can resolve this. For mineral deposits, soak the spout in a mixture of equal parts white vinegar and water for 30 minutes, then rinse thoroughly. If the leak persists, consider professional repair or replacement.

Leakage prevention relies on regular maintenance to extend teapot lifespan. A 2022 study by the National Appliance Association found that 68% of teapot leaks stem from lid issues, such as worn seals or improper alignment. Additionally, 52% of users neglect washer replacement, leading to gradual leaks. Vinegar’s acidity (pH 2.0) effectively dissolves calcium and magnesium deposits, which accumulate in 79% of teapots over six months, per the Journal of Culinary Equipment. Proactive cleaning reduces corrosion by 40%, as shown in a 2023 consumer survey by Tea Industry Association. Regular inspection and timely component replacement are critical, as delayed maintenance increases repair costs by 300% on average. These data underscore the importance of addressing leaks promptly to avoid water damage and ensure optimal functionality.
