Evapo-Rust rust Remover
EVAPO-RUST is an amazing award winning rust REMOVER which is utilized by the U.S. Army, U.S. Navy, U.S. Air Force, FBI, NATO, Government Contractors, Engine Builders, Auto Enthusiasts, Gunsmiths, Forensic Labs, OEM’s, Farmers, Antique Restorers and more.

EVAPO-RUST is non-corrosive to steel and does not harm brass, copper, aluminum, gold, lead, titanium, steel, cast iron, chrome solder points, vinyl, plastic, rubber, silicone, glass, cork, or wood. EVAPO-RUST has an indefinite shelf life* and can be used over and over until it absolutely stops working. On average, one gallon de-rusts up to 300 pounds of light to moderately rusted steel.

Evapo-rust is safe Listed as a SCAQMD Certified Clean Air Solvent Not an eye irritant No VOC's No Acids Not a skin irritant No HAP's No Caustics Non-Toxic dermally or orally Non-Corrosive No Solvents Non-Hazardous Non-Flammable Biodegradable

Easy To Use

EVAPO-RUST is easy to use.
Fully immerse the rusted item in EVAPO-RUST and check progress in about 30 minutes; no scrubbing necessary.
Soak times will vary from 30 minutes to 24 hours depending on severity of rust, type of steel, and temperature.
EVAPO-RUST is water based, therefore the active molecules will slow down as temperature decreases and increase as temperature increases. (We recommend utilizing EVAPO-RUST at a bath temperature above 60° F.)

EVAPO-RUST has a surfactant to aid in penetrating oils and dirt. However, surface contaminants do slow the process and can shorten the life of EVAPO-RUST . Oils, greases and cosmoline should be removed prior to de-rusting. Cleaning the part prior to soaking in EVAPO-RUST will also help in the disposal of the spent product.

EVAPO-RUST is unique

EVAPO-RUST works at a pH of 6.1 to 7 (neutral) through selective chelation. This is a process in which a large synthetic molecule forms a bond with metals and holds them in solution. Most chelating agents bind many different metals. The active ingredient in EVAPO-RUST bonds to iron exclusively. It can remove iron from iron oxide, but is too weak to remove iron from steel because the iron is held much more strongly.

How Evapo-rust affects coatings
EVAPO-RUST is highly recommended by the NRA gunsmithing school and is utilized by FBI, CIA, NATO and other law enforcement and forensics agencies. EVAPO-RUST is perfect for removing weapon finishes such as Bluing, Parkerizing, Zinc Phosphate, and Browning. Anodizing, powder coating, chrome, nickel, paint, and most other coatings will not be removed as long as they do not contain oxides. EVAPO-RUST will not harm lead or solder points.

Transportation and Disposal
EVAPO-RUST is non-hazardous and ships U.S. Postal, UPS or regular freight (class 55). The product is sewerable in neat form and, in most cases, only the chelated iron content of the solution will dictate disposal requirements. The pH of virgin EVAPO-RUST is 6.1. The pH of the spent solution will vary from 6.1 to 7, which means there is no need to neutralize the already neutral solution. Check with your local water treatment facility and dispose of according to local, state, and federal guidelines.

Shelf life and Use life
EVAPO-RUST has an indefinate shelf life* and can be used over and over until it absolutely stops working. Only water is lost to evaporation. EVAPO-RUST has a tremendous work load. One gallon can remove 1/2 pound of pure dry rust. Rust is about 1/17 the weight of iron by volume, which means its workload is substantial. On average, one gallon de-rusts up to 300 pounds of light to moderately rusted steel. As the iron is removed from the iron oxide, carbon from the rust is released. Some parts may have a black film after using EVAPO-RUST. High carbon steel and tool alloy steel items, when de-rusted, will have a darker appearance. The carbon can be removed simply by wiping with a cloth when rinsing with water. The more you de-rust, the blacker the solution becomes. EVAPO-RUST is spent when it is pitch black and no longer performs.

*Shelf life is for un-opened product. Once opened, The life of the bath will vary due to biodegradability (bacteria introduced into the solution). After using Evapo-Rust, it is better to cover the solution, but still allow air to the bath. Pouring the solution back into a sealed container will allow the anaroebic bacteria to begin the degredation process. Used, open baths have continued to operate for over a 12 month period.
