Bluestone is a popular building stone for fireplaces.
Bluestone is a bluish-gray sandstone. It is very beautiful, and is used for a variety of indoor and outdoor surfaces, such as fireplaces and patios. If you have hard water in your area, over the course of your bluestone's life it may develop some lime deposits. Fortunately, lime can be removed from any surface--even a delicate one like sandstone--using some common household cleaning agents that you can probably find in your kitchen right now.
Instructions
1. Saturate a cleaning rag with the white vinegar. It should be soaked, but not dripping, so that you do not get vinegar all over your floor.
2. Lay the rag over the lime deposits. Leave the rag in place for 15 minutes. The vinegar will loosen and dissolve the lime.
3. Scrub away the lime deposit. Use the rag and firm pressure, but do not scrub back and forth any more than necessary so that you do not wear a groove in the stone. Use circular motions if possible.
4. Sprinkle the area with baking soda. It may fizz a little in the vinegar. The baking soda will minimize the vinegar odor and help abrade any remaining deposits off the bluestone when rubbed with the vinegar-saturated cloth.
