The best way to store kerosene is in an approved container or larger storage tank. It's important to store kerosene in a room temperature environment with as little exposure to sunlight as possible.
Metal storage containers are better for long-term kerosene storage than plastic containers. Unapproved plastic containers can actually degrade the kerosene over time. Kerosene storage containers are often blue rather than red. This helps people distinguish them from gasoline storage containers. Experts recommend storing kerosene for no longer than one year. Older kerosene does burn, but not as well as newer kerosene. Proper storage increases the lifespan of kerosene.
