The cleaning methods depends on the shape, material, and overall type of broom you have. In general, you can comb it or use a vacuum hose to clean any type and size of bristles if there is too much hair and dust to shake off. Besides such a daily ritual, it is also recommended to soak the broom in water and dish soap solution. Do this at least once a month. Let is soak for a while and rinse to let dry before using again.
