A floor brush picks up a lot of dirt…but how often does it occur to you to give it a clean? It’s one thing picking out the clods of dust and hair that get trapped in the bristles, but it’s a good idea also to wash them in a warm mild detergent solution from time to time.
If you do it in the bath, you’ll see how dirty the water will be!
Rinse in clear water, then hang to dry. Always store your brush bristles side up – that way they won’t be flattened and will stay nice and bouncy.
