Stone Slabs Cleaning Tips
Granite gravestones can be cleaned with the help of natural clean water,
a non ionic detergent, and biocidal cleaning material. They can be
cleaned just like marble, limestone, or sandstone headstones.
If the stone is in good and stable condition and does not have any
contrasting paint on the engraving, you may use a pressure washer, too.
You can gently scrub the surface with a scouring pad to remove calcium
deposits on polished granite tombstones.
A bronze gravestone can be cleaned by rubbing it with a scrub brush
soaked in a solution of one tablespoon of dish soap mixed in half a cup
of water.
Rinse it with water and then spray distilled water on it to make the
surface chemically inert. Finally, wipe it with a towel or use
compressed air.
To maintain the attractive appearance of a bronze grave marker, rub a
thin layer of paste wax on the memorial monument and brush the surface
with the help of a shoe brush.
After a few minutes, bluff the surface in small circular motions using a dry scrub brush and rebuff with a flannel cloth.
