All sculptures are sealed so they are washable using detergent and water. Scrub occasionally as needed with a stiff bristle brush. 
 
Exterior Use
Sculptures are best placed in sunlight, not under trees!  Keep the base of the sculpture elevated off the soil. A good idea is to place the sculpture on an exterior tile or marble tile, and then on the base. If there is any sign of algae growing, spray with a general moss and mould killer mid-summer. Reseal every two years, or as needed, with a water based silicone masonry spray (follow sealer instructions).
