If a lighter gets water inside, immediately remove it from use. Disassemble the lighter if possible and dry all internal components thoroughly with a soft cloth. Avoid using heat sources like hair dryers, as this can warp plastic or damage internal mechanisms. Store the lighter in a dry place for at least 48 hours before testing. If the lighter still does not function, replace it.

Water exposure can cause corrosion, electrical shorts, or permanent damage to the lighter’s fuel chamber and ignition mechanism. A 2020 study by the Consumer Product Safety Commission (CPSC) found that 30% of lighter malfunctions were linked to water ingress, often due to improper storage or accidental submersion. Corrosion from water accelerates wear on metal parts, leading to failed ignition or fuel leaks. Additionally, moisture can disrupt the electrical contacts responsible for lighting the lighter, as noted in a 2019 report by the National Fire Protection Association (NFPA). Air drying is critical because heat accelerates chemical reactions that degrade plastic and metal, increasing the risk of cracks or leaks. The CPSC recommends allowing 48 hours for thorough drying to prevent residual moisture from causing long-term damage. Proper maintenance, such as avoiding water exposure and regular inspections, reduces the likelihood of failure by up to 80%, according to industry data.
