There are a few simple, easy ways to keep your commercial shower cubicles clean and free from mildew. For glass panels, you can easily clear away soap and shampoo marks with an acidic solution of vinegar in water or lemon juice, and to take care of mildew, you only need a solution of water and bleach, with a brush to scrub away the first signs of mould and mildew on your showers walls, corners, trays, and panels.
