Phosphoric Acid Descaler Rust Remover 30% Safe On Metal Surfaces – 25L
- This phosphoric acid removes RUST.
- Safe on metal surfaces including stainless steel and will not cause “flash rusting” when used for etching concrete.
- Phosphoric acid may be used to remove rust by direct application to rusted iron, steel tools, or other surfaces.
- The phosphoric acid changes the reddish-brown iron oxide.
- Multiple applications of phosphoric acid may be required to remove all rust.
- Other applications:
- Among many applications, phosphoric acid is used:
- As a solution for anodizing
- 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 oxidizing agent for activated carbon production, as used in the Wentworth Process.[15]
- 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 planarization.
- 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: for example, in combination with hydrogen peroxide and water it is used to etch InGaAs selective to InP.[16]
- Heated in microfabrication to etch silicon nitride (Si3N4). It is highly selective in etching Si3N4 instead of SiO2, silicon dioxide.[17]
- 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.[18]
- As a dispersing agent in detergents and leather treatment.
- As an additive to stabilize acidic aqueous solutions within a wanted and specified pH range.
- As a sanitizing agent in the dairy, food, and brewing industries
Direction for use –
- Always dilute product with water before use.
- Dilute with up to 5 parts water depending on the degree of scale to be removed.
- Rinse thoroughly with clean water after descaling is complete.
