REMOVAL OF BLACK WATER AND TANNIN STAIN
A common form of staining on wood surfaces results from contamination with iron. A portion of the extractives in wood includes a group of chemicals collectively called tannins. The amount of tannins depends on species; oak, redwood, and cedar are rich in tannins. Tannins react with iron to form a blue-black stain on wood. Common causes of iron stain include use of un-galvanized or poorly galvanized fasteners; OXALIC ACID brushed into the stains makes removal easy. Finishing wood with a WATER REPELLANT WITHA PRESERVATIVE AND/OR WOOD POLISH OR OIL greatly minimizes further iron stain and enhances the finish of the wood.. Wood must be clean; free of paint, waxes, oils and dirt. Use wood cleaners to remove any grease oils or grime. Use paint strippers to remove any finish, paint or coating.
