Stone Cast Fountain Care and Maintenance • Do not use any corrosive chemicals as this might corrode the outside surface. • Stonecast objects experience natural aging, which to most adds distinctive appeal. Sealer spray applied annually will restore any lost luster. • Clean with ordinary water and brush when necessary to remove dirt and grime. • During winter or cold temperature weather, drain out all water and cover properly when not in use. If left uncovered/unprotected water in the crevices can freeze and cause outer layer to pit, crumble or crack. • Unless properly treated, all water features experience calcium buildup.
