Obviously, a broom is an energy-efficient way to keep your floors clean at home. But do you ever wonder how you can clean a broom? A mixture of hot water and salt creates a saline solution that disinfects naturally and helps clean, too. Just soak the broom in a bucket of very hot, salty water for about 20 minutes. Let it air dry, and it’ll be good as new. Fill a spray bottle with a little of the salt-water solution, and use it to deodorize the inside of smelly sneakers. If you’ve got weeds, pour salt water right on top to zap them away.
