Phosphoric acid is a highly effective and versatile chemical solution with a wide range of applications across various industries. Its unique properties make it an ideal solution for removing rust, cleaning surfaces, and adjusting pH levels. With its ability to change the reddish-brown iron oxide, phosphoric acid is commonly used to remove rust from iron, steel tools, and other surfaces. Multiple applications may be required to achieve desired results.

This 30% Phosphoric Acid solution is a powerful and effective de-scaler and rust remover, safe to use on metal surfaces including stainless steel. It is ideal for removing rust and scale from iron, steel tools, and other surfaces and will not cause flash rusting when used for etching concrete. Phosphoric Acid is useful for multiple applications in industries such as anodising, biology, chemistry, and more.

Please see full list below for the various applications Phosphoric Acid 30% is used:

  • As a solution for anodising
  • As an external standard for phosphorus-31 Nuclear magnetic resonance (NMR).
  • As a buffer agent in biology and chemistry; For example, a buffer for high-performance liquid chromatography.
  • As a chemical oxidising agent for activated carbon production, as used in the Wentworth Process.
  • As the electrolyte in phosphoric acid fuel cells.
  • With distilled water (2–3 drops per gallon) as an electrolyte in oxyhydrogen generators.
  • As a catalyst in the hydration of alkenes to produce alcohols, predominantly ethanol.
  • As an electrolyte in copper electropolishing for burr removal and circuit board planarisation.
  • As a flux by hobbyists (such as model railroaders) as an aid to soldering.
  • In compound semiconductor processing, phosphoric acid is a common wet etching agent
  • Heated in microfabrication to etch silicon nitride (Si3N4). It is highly selective in etching Si3N4 instead of SiO2, silicon dioxide.
  • As a cleaner by construction trades to remove mineral deposits, cementitious smears, and hard water stains.
  • As a chelant in some household cleaners aimed at similar cleaning tasks.
  • In hydroponics pH solutions to lower the pH of nutrient solutions. While other types of acids can be used, phosphorus is a nutrient used by plants, especially during flowering, making phosphoric acid particularly desirable.
  • As a pH adjuster in cosmetics and skin-care products.
  • As a dispersing agent in detergents and leather treatment.
  • As an additive to stabilise acidic aqueous solutions within a wanted and specified pH range.
  • As a sanitising agent in the dairy, food, and brewing industries.

Tip:
Make sure to work in a well-ventilated area to avoid inhaling the fumes

Please note: This product can be dangerous if not handled correctly. By purchasing this item, you agree that you are competent in its usage and take responsibility for the risk involved.

  1. Always wear protective gloves, goggles, and clothing when handling phosphoric acid.
  2. Ensure the surface to be treated is clean and free of debris.
  3. Apply phosphoric acid directly to the rusted area using a brush or cloth.
  4. Allow the solution to sit for the recommended time before rinsing with water.
  5. Repeat the process as necessary until the rust is removed.
