  1. 1

    Pour 4.5 litres (1 gallon) of warm water into a bowl and add 2 to 3 tbsp of regular washing up liquid to the water. The water should take on a soapy texture and there will be some foam on the top.

  2. 2

    Dampen a sponge with the soapy water and scrub the granite fireplace vigorously. Make sure to scrub in between grout lines if your fireplace has granite tile.

  3. 3

    Dump out the soapy water and replace it with clean water. Use your sponge to rinse off the soapy water. Make sure to do a thorough job, as any leftover soap will leave a thin, opaque film on the granite's surface.

  4. 4

    Use a towel to dry off the granite. It should be restored to its former brilliance.

Tips and warnings

  • To keep your granite looking as clean as possible, make sure to polish it at least twice a year and seal it once a year.
