How to Remove Stone Fountain Calcium Deposits
Estimated Reading Time: 1 MinutesIf a stone fountain has a copper basin, chances are the stone may get green discoloration. The hard, green deposits are a combination of calcium deposits from the water and copper from the basin. The easiest way to remove them is to use a pressure washer. Be sure to test the pressure washer on an inconspicuous area, since too high a pressure may cause the stone to break apart. We recommend 900 psi. Another method would be to sandblast the deposits from the hole with a micro-blaster. This is a small sandblaster similar to an air brush. When you are done removing the large portions of deposits a mild acid wash should remove the remaining deposits.
