How to Remove Algae From Ironwood

The ironwood tree is found in the Sonoran desert, which spans areas of Arizona, California and Mexico. The tree grows in excess of 45 feet tall and will live for over 1,500 years. During these years the wood of the tree is harvested to create firewood, wood carvings and fence posts. As with any other wood, ironwood is susceptible to algae growth when it comes in contact with moisture. You can remove the algae from outdoor ironwood pieces without any harmful chemicals.
