Granite countertops stain easily.
However, even water can soak into a granite countertop and leave a dark colored spot but this will evaporate in minutes. Liquids that do not evaporate, such as oils will cause stains if left to soak into the stone.
Similarly, how do you get a stain out of granite?
How To Clean & Remove Stains From Marble & Granite
- First blot the spot to lift as much of the substance as possible.
- Next, spray it with water.
- Now slather it completely with a paste made from baking soda and water (to the consistency of sour cream).
- Leave covered for at least 24 hours, the baking soda will dry and pull up much of the stain.
Then, how do you fix discolored granite?
How to Fix Granite Discoloration
- Soak the corner of a cleaning rag with ammonia and gently rub it into biological or oil-based stains, such as those caused by cosmetics, algae, mildew or tar.
- Rub the granite with hydrogen peroxide, using a cleaning rag, to clean ink and marker stains and organic stains such as coffee and milk.
When water or another liquid is left on top of the granite, small amounts of it seep into the stone through its many pores. When the surface spill of water is wiped away, the stone appears darker where the water was standing. What you are seeing is the water trapped inside the granite, filling up these holes.
