Here's an odd question for you. How often do you replace your mops and brooms? I replace my mop once or twice a year. It have a detachable, machine washable head so I detach and wash with detergent and I wash my floors. I have had the same brooms for about 2 yrs. I clean them in detergent every now and again but I think it's time to get new mops and brooms. How often do ou replace yours?
