Swanstone is a natural, mildew-resistant stone that works well in high-moisture areas such as sinks and showers. The stone also resists stains, but does accumulate soap scum buildup just as any other shower does. On a weekly basis, the Swanstone should be cleaned with elements that are not harmful to the Swanstone, but are effective in removing all of the buildup that accumulates through regular use of your shower area.
Pour 2 cups of water, 1 tsp. of dish soap and 1 tsp. of vinegar into a spray bottle.
Spray this mixture onto your Swanstone, and let sit for 10 seconds. The dish soap dissolves the soap scum, while the vinegar disinfects your shower area. Since you are using only small amounts of both ingredients, you can be assured that the solution will clean without damaging your Swanstone.
Scrub the solution off of your Swanstone with a wet cleaning rag. Allow the stone to air dry.
