How to Dispose of Kerosene
If you're stuck with kerosene that you literally can't even give away, you can evaporate the kerosene if you only have a little of it. This is absolutely, positively meant as an option of last resort. It's not recommended but it will work in a pinch.
To do so, place your kerosene can in a safe, open, and well-ventilated area. Choose a place where the kerosene won't be disturbed by kids or pets. Take the cap off the kerosene can and replace it with a screen mesh so that nothing falls into the container. Leave the kerosene to sit open in this manner for a few days until it evaporates. When it has, triple wrap the container in plastic bags and throw it away or store it until you need it again.
