How to Care for a Sandstone Statue

Assess the current state of the statue for signs of chipping, cracking or other fissures in the exterior surface. If there is a lot of damage, it would be best to leave it alone as cleaning it would only accelerate the decay.

Lightly spray the surface with water and brush it gently in a random motion to prevent streaking or erosion. You can use a plastic scraper to remove any large areas of plant life. Rinse the statue repeatedly to prevent excess friction from grinding the surface.

Rinse the statue again, and then apply the non-ionic detergent. You can use a spray bottle, in which the detergent is often sold, or wet your brush and apply it that way. Brush the statue gently using the same random motion, and then rinse off the detergent.

Apply the dichlorophen solution to eradicate any remaining traces of plant life. Dichlorophen is often sold at garden stores and will penetrate the surface to kill any remaining traces of biological growth that may be lingering in the crevices and prevent new growth from occurring. Rinse the statue once again and allow it to air dry.
