5 Tool Magic Holder. An easy to use tool storage rack. It automatically adjusts to any size handle and holds them securely. The perfect way to organize your broom closet, or store sports equipment in the garage.
Mount mop and broom holders on the back of the closet door. (Try the Crawford Spring Grip; $4, acehardware.com.) They'll be out of the way and can air-dry. Even better, for ventilation, insert a screen panel on the lower half of the door.
