Textile Industry

• Used as a bleaching agent for cotton, linen, silk, and other natural fibers
• Removes natural pigments, iron stains, and rust marks for a cleaner, brighter finish
• Essential for achieving uniform dyeing and improved color fastness
• Acts as a reducing agent in dyeing processes to enhance vibrancy and consistency

Metal Treatment & Cleaning

• Premier cleaning agent for rust removal from metal surfaces and machinery
• Forms water-soluble ferrioxalate complexes for easy rust dissolution
• Widely used in radiator scale removal, boiler descaling, and mineral deposit cleaning

Wood & Stone Restoration

• Bleaches wood, eliminates stains, and restores the natural color of decks, furniture, and flooring
• Effective in cleaning and brightening marble, stone, and concrete surfaces

Water Treatment & Industrial Processes

• Chelating agent for heavy metals—precipitates calcium, magnesium, and iron
• Used for pH control, surface preparation before metal finishing

Paper & Pulp Industry

• A key ingredient in pulp bleaching for high-brightness paper products
• Removes lignin and impurities during manufacturing for superior appearance

Semiconductor Industry

• Utilized in copper layer planarization during chip production
• Ensures smooth, uniform electronic surfaces
