How do I maintain the shower? You can maintain the shower as you would any other shower. You have to clean the shower by spraying it down with cleaning supplies. The best cleaning supplies for bathroom remodeling is the mildew and mold cleaners, since showers produce moisture. The sprays will help keep mildew and mold away. In addition, there are long brushes used to clean hard spots and above the head. The brushes are great for reaching areas you ordinary could not reach.
