For removing dark stains and brightening bare or stripped wood, choose an oxalic acid product whose form and package size match the job. Savogran is a straightforward choice for occasional wood bleaching, while Ecoxall and MAXTITE offer larger powder quantities for repeat or broader cleaning tasks. The 12-ounce LIVING SOLUTIONS product is a smaller option, and Ecoxall’s one-pound package offers a middle ground. Always follow the product label and test the solution on an inconspicuous area first.

Savogran Oxalic Acid Wood Bleach
Savogran is the most directly wood-focused option in this group. Its listed features say the concentrate is mixed with hot water and can bleach unfinished or stripped wood. That makes it a practical choice for furniture or other bare-wood projects where dark discoloration needs attention before refinishing.
Best for: Buyers who want a product specifically described for bleaching unfinished or stripped wood. Choose this if you prefer a named wood-bleach product rather than a bulk powder marketed for several uses.
Limitation: The package is 12 ounces, and it must be mixed with water. Follow the label for the correct preparation and application directions.
ECO LIVING SOLUTIONS Oxalic Acid
This 12-ounce product is listed as oxalic acid for deck stain and wood stain removal, as well as metal cleaning and rust-stain removal. Its smaller package may suit a homeowner handling a limited stain-removal project rather than stocking a larger quantity.
Best for: Buyers seeking a compact oxalic acid product for wood or deck stain-related cleaning. It was selected because its name explicitly identifies wood stain removal and several related cleaning uses.
Limitation: The provided product details do not specify a mixing ratio or application steps. Check the package instructions before preparing or applying it.
Ecoxall Oxalic Acid Fine Powder, 1 Pound
Ecoxall’s one-pound fine powder is listed as 99% pure and intended for wood brightening, stain removal, and cleaning metal and other surfaces. Its product details specifically mention lifting dark stains, tannins, and discoloration from bare wood before refinishing or restoration.
Best for: Buyers who want a multipurpose powder in a moderate package size. Choose this if the project involves bare wood and you also value the listed uses for metal or other surfaces.
Limitation: This is concentrated powder, not a ready-to-use liquid. The supplied details do not give a dilution ratio, so use the label rather than estimating a mix.
MAXTITE Oxalic Acid, 2 Pounds
MAXTITE is listed as 99.6% pure oxalic acid for metal and wood cleaning, bleaching, and rust removal. The two-pound quantity is suited to buyers who expect to use oxalic acid repeatedly or across more than one cleaning task. Its listed packaging includes an HDPE container with a resealable child-resistant cap.
Best for: Buyers comparing larger quantities and a stated purity level for wood and metal cleaning. It was selected for its explicit wood-bleaching use and resealable container.
Limitation: The provided listing details do not specify wood-specific mixing instructions. Confirm the label directions and use only as directed.
Ecoxall Oxalic Acid Fine Powder, 2 Pounds
This 32-ounce Ecoxall package is listed as 99% pure fine powder. Its stated uses include deck stain removal, cleaning wooden furniture and metal surfaces, and brightening bare wood by lifting dark stains, tannins, and discoloration before refinishing.
Best for: Buyers who need more powder than the one-pound option for repeated or larger jobs. The listed wood-brightening uses make it a relevant choice for restoration work.
Limitation: The larger package may be unnecessary for a single small project. The product is powder, so preparation and safe handling depend on the label directions.
Buying Guide: How to Choose Oxalic Acid Wood Bleach
What type of wood stain are you trying to remove?
Oxalic acid products are commonly marketed for dark stains, tannins, discoloration, and rust-related staining. The listings for Ecoxall specifically describe use on bare wood to lift dark stains and tannins. Identify the stain and read the product label before choosing; a wood bleach is not automatically appropriate for every finish or surface.
Should you choose a powder or concentrate?
Powder products offer a dry format and may be available in larger quantities, but they require preparation according to the label. Savogran is described as a concentrate mixed with hot water. Compare the product instructions before buying, since the supplied information does not provide a consistent mixing ratio across these options.
How much should you buy?
For a limited task, the 12-ounce products may be sufficient, while one- or two-pound powders may better suit repeat use or larger projects. Do not select a larger quantity solely because it is available; consider the project area, storage needs, and label directions.
What precautions matter?
Oxalic acid is a chemical, so handle it carefully. Read the full label, use the protective equipment and ventilation the label recommends, keep it away from children, and avoid mixing it with other cleaners. Test a small, inconspicuous area and follow the manufacturer’s directions for application, cleanup, and disposal.
