446163880-Zinc-MaintenanceThe zinc alloy used in the base of this light will look white in colour when first installed in the landscape (as shown in image). This is due to the acidification of the zinc oxide. As time passes, this white deposit will wash off and make way to a lovely dark-grey patina.
To maintain this fixture and make sure it's always looking it's best only simple maintenance with water and soap is needed. The manufacturer recommends avoiding scouring sponges and abrasive products as they remove the natural patina.
