Blast cleaning wood can be accomplished successfully using corn cob grit. The pictures below depict a graffiti covered wood bridge, both before and after blasting with corn cob grit. This graffiti removal operation was accomplished using a Portable Pressure Blast System with two different grit sizes of corn cob. These excellent results allowed the bridge to be restored to its original condition and beauty. Similar processes are used for log home cleaning. Wood restoration after fire and water damage can also be accomplished using corn cob blasting.
