Description du produit
Product Overview
High Purity 99.6% Oxalic Acid Industrial Grade is a highly effective crystalline organic compound renowned for its powerful reducing and chelating properties. As one of the simplest dicarboxylic acids, this product serves as an indispensable tool across industrial applications, restoration projects, and maintenance tasks. Formulated to a strict purity standard of 99.6%, this industrial-grade powder delivers consistent, reliable results for neutralizing rust on heavy machinery, revitalizing weathered timber, or removing mineral stains from natural stone. Supplied in durable 25kg bags, this product offers high-volume efficiency and superior chemical performance.
Key Features & Benefits
- Exceptional Purity (99.6%): Maximum reactivity with lower usage rates for cost-effective bulk industrial operations, free from fillers or impurities that can leave residues.
- Powerful Chelating Agent: Converts insoluble metal oxides into soluble complex ions for easy rinsing, effective on iron and steel without excessive pitting when used as directed.
- Versatile Restoration: Dual-action formula acts as both potent rust remover and brilliant bleaching agent, neutralizing dark tannins and iron stains to restore natural wood appearance.
- Safe on Masonry: Effective for cleaning efflorescence, mortar smears, and iron oxide stains from marble, granite, concrete, and terrazzo without surface etching risks.

Applications
Rust Removal (Metals)
Oxalic acid is the industry standard for removing rust from ferrous metals. Used in automotive repair for chassis components, marine maintenance for deck hardware, and industrial fabrication for pre-treatment before painting or powder coating. Unlike mechanical abrasion, it dissolves corrosion chemically, leaving a clean, "pickled" surface ready for finishing.
Wood Bleaching & Brightening
Woodworkers and restoration specialists rely on oxalic acid to correct "iron tannate" stains—black or blue-black discolorations from iron contact with oak, cedar, or mahogany. Effective for bleaching general water stains, weathering, and yellowing, restoring natural beauty of exterior siding, decks, and wood flooring before finishing.
Stone & Masonry Cleaning
Offers safe yet effective solution for removing stubborn rust stains from irrigation systems, rebar, or metal furniture. Effectively cleans efflorescence and cement smears on marble, travertine, and granite tiles without compromising structural integrity or polish.
Usage Guidelines
Preparation: Always add crystalline powder to cold water (never add water to acid). For heavy rust removal or bleaching: 1 part oxalic acid to 10 parts water (approximately 100g per liter). For light cleaning or delicate surfaces: 1:20 ratio.
- Surface Preparation: Ensure surface is clean of grease, oil, or loose debris.
- Application: Apply solution using plastic sprayer, brush, or by soaking. For vertical surfaces, apply from bottom up to prevent streaking.
- Dwell Time: Allow solution to sit for 10-15 minutes. Do not let solution dry on surface; reapply if necessary to keep area wet.
- Agitation: For heavily rusted metals or deeply stained wood, gentle agitation with stiff nylon brush accelerates reaction.
- Rinsing: Thoroughly rinse treated area with copious clean water to neutralize acid and remove dissolved contaminants.
Safety & Handling
Oxalic acid is a corrosive material requiring proper safety protocols. Operators must wear chemical-resistant gloves (nitrile or neoprene), safety goggles, and protective clothing. Avoid inhalation of dust during mixing; use in well-ventilated area or wear dust mask. Store in cool, dry, well-ventilated area away from incompatible materials. Keep 25kg bags sealed to prevent moisture absorption and caking. For skin contact, wash immediately with plenty of water. For eye contact, rinse cautiously with water for several minutes and seek medical attention.
Packaging & Logistics
Supplied in sturdy 25kg woven polypropylene or kraft paper bags with inner polyethylene liner for humidity and contamination protection. Packaging designed for easy palletization and handling, with 40 bags typically stacked per metric ton pallet for efficient warehousing and distribution.
Whether you are a professional restorer, metal fabricator, or facility maintenance manager, High Purity 99.6% Oxalic Acid offers the strength, purity, and versatility required for toughest cleaning and restoration challenges. Combining chemical efficiency with material safety, it stands as the premier choice for bleaching wood, removing rust from metal, and restoring elegance of marble and stone.
