I have a 6 ft. tall bronze statue of two brown pelicans sitting on a piling. Water comes from both the pelicans mouths. The statue has the name 'S David' on it. I am trying to contact the sculpter to ascertain how to clean and maintain the piece. The internal line(s) which presumably are copper may be clogged. How to clear? Also, how to clean the exterior? Pressure wash? If so how much pressure?
