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), HOODBLEACH™-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, such as our HOODBLEACH™-190,
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.
The degree of bleaching is a function of how long part B is
allowed to dwell on the surface and react with A. That is, a half hour, four
hours, overnight, etc. Often reapplying A on top of B again after about an hour
may be necessary or repeating the cycle, i.e., A than part B again. However,
mixing A & B together prior to application or at any time, must be avoided.
A violent and harmful chemical reaction will occur that is a safety hazard.

OXALIC ACID WOOD TONER
Use as the final stripping step to give the
wood complete color control. Restores clarity and the natural look of
the wood without effecting the patina. DOES NOT BLEACH THE WOOD – ONLY
RESTORES THE NATURAL COLOR. For best results dissolve 3 to 5 oz per
gallon of warm water then apply by spray, brush or wipe on. Works very
effectively after stripping with HOODSTRIP®-290,
HOODSTRIP®-295, or HOODSTRIP®-410.
CAUTION! DO NOT INTERMIX OXALIC ACID WITH ANY
OTHER PRODUCT. MIX WITH WATER ONLY! SUPPLIED IN POWDER FORM.
