There can be many problems attached to oak staining especially with green oak. Unstightly stains and marks can spoil good looking beams or floors. Dark Spots and discoloration of the wood can be removed with Oxalic Acid. Oxalic Acid can also be used to freshen wood colour if it has become grayed due to external exposure. In the refinishing of wood furniture, oxalic acid can be used after stripping to lighten and soft darker stained areas before refinishing. It can also be used as a rust remover and a stain remover in many other applications. In removing iron stains users can scrub the stained area with a solution of oxalic acid in water.
