Understanding Wood Toning, Bleaching
and Stain Removal
A wood toner, such as Oxalic
Acid, removes dark stains and brings darkened wood's patina due to age,
weathering or pH back to its natural color, or close to it. However, it will not
bleach the wood color away or remove stain colorants
To remove aniline dye stains from the wood
surface (or grain), HOODBLEACHT-192 (Stain-Away) is the product
recommended for the job. This product will not tone, brighten or bleach the wood, or remove pigment type stains.
Finally, to change yellow pine to white pine,
red oak to white oak, etc., a two part bleaching system is needed. Part A is applied first followed by Part B. Part A opens up the grain
upon penetration, while part B reacts chemically with part A and bleaching
occurs through oxidation. We no longer offer this type of bleach.
