Step 1: Sweep the Floor
A clunky vacuum cleaner is almost no help in a small bathroom. Instead, keep a small broom in your linen closet. Sweep along the edges of the room and work to collect dust and dirt in the middle. Don't forget to reach around the base of the toilet where dust likes to collect!
An easy way to pick up your small dust pile is with a slightly damp paper towel.
Step 2: Skip the Cleaning Bucket
Keep your cleaning bucket stowed while you clean the bathroom floor. Instead of hauling it upstairs with your mop, turn the bathroom sink into a makeshift bucket.
All you need to do is close the drain and fill the sink with 2 gallons of warm water. Add a 1/4 of vinegar and 1 tablespoon of dish soap; mix until suds form. Submerge a rag into the mixture and wring away excess water. Rinse the rag between passes.
Step 3: Dry Floors
Towel-drying your floors is the best way to make sure they're left sparkling. But why make it any harder than it needs to be? Instead of crouching down on your hands and knees to dry them, lay a large towel on the ground. Find your balance and put one foot on the towel to move it around the bathroom floor, section by section. Large bathrooms may require two towels, depending on how wet they get.
Be sure you're starting at the far end of your bathroom so you finish drying by the door. This way you don't have to walk over your freshly cleaned floors to exit.
