Note:  We don't ship our Born Again Brighterner so we recommend buying a Wood Brightener locally maybe.  Ours is Oxalic Acid based.  It reverses darkening of wood without damaging wood fiber or removing color like Chlorine Bleach does (which we don't recommend using- it REMOVES COLOR AND DAMAGES WOOD !!).  Brighteners are especially important on Tannin oriented woods like Cedar and Rewood.
