FAQ - Frequently Asked Questions

Is Evapo-rust is 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.

Yes, Even Motorcycle Tanks
You can use Evapo-Rust to remove the rust from a gas tank in one of two ways described below, depending on if your tank is still attached or has been removed:

1)  Completely fill the tank with Evapo-Rust and allow to sit for 2 – 4 hours.  Drain completely and rinse well with water.  Air dry and fill with gasoline immediately to eliminate flash rust.

2)  Pour in 1 gallon of Evapo-Rust and rotate gas tank every hour until the rust has been removed.  Drain completely and rinse well with water.  Air dry and fill with gasoline immediately to eliminate flash rust.

Happy Customer Comment

I just received and tried a gallon of evaporust yesterday. This stuff is absolutely amazing. Sort of like millions of little rust termites eating away. I’m usually a non-believer until proven (that’s the engineer in me). I’ll be informing all of my gear head buddies of how good it really is.

How it Works - Click on image for larger size.

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.

After De-Rusting
Once the item has been de-rusted, you have several options: 1)Wash and rinse the item off and go to the next process for painting, coating, etc. 2) Wash & rinse the item off and apply a long term rust inhibitor (see next paragraph); or 3) Wash and rinse the item and dip back into EVAPO-RUST, remove and let dry. EVAPO-RUST will provide about 10-14 days of rust inhibition, depending on the humidity. Wash and rinse when ready to paint or apply long-term CPC.

To protect the cleaned metal during storage or shipment, use CP-90, Rust Inhibitor.

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. EVAPORUST is perfect for removing oxide weapon finishes such as Bluing, Parkerizing, Zinc Phosphate, and Browning. Evaporust will remove black oxide coatings from cutting tools, if soaked. Anodizing, Cobalt Tungsten Carbide, 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.

Evapo-rust 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.

Evapo-rust shelf life and use life
EVAPORUST 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.
