Evapo-Rust is a non-toxic, non-hazardous, non-flammable chemical with a targeted process of removing rust (iron oxide). Evapo-Rust removes the iron oxide into solution by a proprietary process called selective chelation. As the normal operational pH is 6 - 7, the solution is never hazardous to handle, store, or dispose of in neat form. PPE is not required with Evapo-Rust, making it an excellent industrial and consumer product. There are no transportation restrictions, air or ground, for Evapo-Rust. Waste generated by Evapo-Rust is typically non-hazardous and has potential use as lawn and garden fertilizer.

Chelation is the binding of metals by an organic compound by the sharing of electron pairs. Evapo-Rust employs a proprietary selective-chelating agent. The molecule latches on to free Fe II on the surface of the metal. The chelated iron is then converted to ferric sulfate by a non-toxic sulfur compound. It also allows the chelating agent to remove more iron from the iron oxide. The molecule does not have sufficient strength to break iron-to-iron in un-rusted steel; hence it is self-limiting and non-corrosive. The solution is no longer viable after removing approximately 1/2 lb of iron oxide per gallon of solution. *Note: Evapo-Rust is NOT based on the action of EDTA, citric acid, glycolic acid, or their sodium salts.

Description

[Harris International Labs] A brand name for a non-acidic rust removing solution. Evapo-Rust uses a selective chelation system to target iron oxide then remove it from the metallic surface as Ferric sulfate. The system does not have sufficient strength to break the iron-to-iron bond thus leaves the non-rusted metal intact. After rust removal, the metal surface may be rinsed with water, then painted, plated, or coated.

Risks

  • Non-toxic, non-hazardous and non-flammable
  • Waste is safe for any disposal method
  • Evapo-Rust: SDS

Physical and Chemical Properties

  • Safe for plastics and rubbers
  • Solution is neutral (pH = 6.1)

Working Properties

  • No dilution or preparation is needed for the solution.
  • Piece must be submerged in Evapo-Rust. Brushing or wiping on will not work
  • Evapo-rust solution is spent when it turns black.
  • Removing dirt from the object will speed the rust remove process
  • Litgh rust amounts may be removed in 30 minutes, but deep rust may require overnight soaking

Forms and Sizes

  • Available in 1 gallon, 5 gallon and 55 gallon sizes.

Resources and Citations

  • The Rust Store: Evapo-Rust
  • Fran Ritchie, National Park Service, contributed information, June 2022.
