If your floor is exceptionally dirty, it’s a bit of a multi-step process, says Katie Gibson, a representative for Lemon and Pine Cleaning Company. “Vacuum the floor thoroughly and then fill a bucket with warm water and the appropriate cleaning solution,” she explains. “Mop the floor and constantly rinse out your mop. At the end, if the water is extremely dirty, dump it out and fill the bucket again. Repeat this process until the water is clean.”
