Fill a spray bottle with 1 qt. warm water.
Add 3 tbsp. baking soda.
Close the spray bottle and shake for several minutes until all of the baking soda has dissolved.
Spray the baking soda over the entire surface of the stone shower. Let the solution sit for at least two minutes.
Scrub the stone surface with the sponge side of a squeegee. Do not use a rough bristled brush as this could scratch the stone surface.
Rinse off the baking soda solution with water from the shower head.
Let the stone shower air-dry.
