Did you know? The most abrasive chemical in your bathroom is ironically, the soaps and shampoos which you use. If soap suds are not regularly washed off your shower fittings or glass surfaces and walls, they will cake up and form a stain on them. Over time, it may even eat into the protective plating and cause rusts. The best policy therefore is to spray over the inside of your shower/bathtub/basin area to rinse away the soap suds after every shower.
