Calcium deposits often form on marble showers when hard water is present in the home. This can quickly dull the appearance of the marble, requiring you to find a product that will clean the calcium deposits without harming the marble finish. Commercial products are on the market that will take care of this problem; however, they may cost more than you are willing to pay. Making a homemade solution is the perfect alternative.
Pour three parts water and one part vinegar into a spray bottle.White vinegar will disinfect and break apart the calcium deposits without harming the marble surface.
Add a tbsp. of liquid dish detergent to the solution; this will also help cut through the calcium and leave behind a streak-free shine.
Twist the cap onto the bottle, and shake gently to combine all ingredients.
Spray the solution directly onto the areas affected by the deposits, and scrub with a sponge. Repeat as needed until all signs of the calcium deposits are gone.
Use the spray weekly as a maintenance treatment, which will keep the shower clean and free of calcium.
