EVAPO-RUST
Neutral Rust Remover

EVAPO-RUST^TM is an amazing neutral pH rust REMOVER which has fully demonstrated its ability to decrease the maintenance burden, increase readiness, decrease costs and increase morale. A product of extensive research, EVAPO-RUST^TM removes even deep rust on all types of mild steel and iron. EVAPO-RUST^TM is water based and does not require any special equipment or personal protective wear. It is non-corrosive to steel and does not harm brass, copper, aluminum, gold, lead, titanium, steel, cast iron, solder points, vinyl, plastic, rubber, silicone, glass, cork, or wood.

FT. Hood: Tank tracks, engine parts, and Hoffman's. A Hoffman Device is a device that attaches to the 120mm gun of the M1A2 tank to simulate live firing. It is made up of several fluted tubes which, after firing and maneuvers, is coated with carbon and rust. Historically, each Hoffman Device required 2 personnel 4 to 8 hours of manual scrubbing to de-rust/clean. With EVAPO-RUST^TM, the troops are able to de-rust 4 Hoffman's every 20 minutes utilizing a 110 gallon plastic water trough and only two personnel; a savings of 174 man hours and 20 personnel (assuming 22 Hoffman's)! After de-rusting, the Hoffman's are wiped clean with VPW SC-1000. The time saved is available for tank recovery resulting in increased readiness and morale!

DIRECTIONS
EVAPO-RUST^TM is easy to use. Fully immerse the rusted item in EVAPO-RUST^TM 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^TM is water based, therefore the active molecules will slow down as temperature decreases and increase as temperature increases. We recommend utilizing EVAPO-RUST^TM at a bath temperature above 50° F.

WEAPONS/FINISH COMPATIBILITY
EVAPO-RUST^TM is highly recommended by the NRA gunsmithing school and is utilized by FBI, CIA, NATO and other law enforcement and forensics agencies. EVAPO-RUST^TM perfect for removing weapon finishes such as Bluing, Parkerizing, Zinc Phosphate, and Browning. Blueing and zinc phosphate coatings (heavy zinc per MIL-DTL-16232 and light zinc per TT-C-490) can be removed both at room temperature (@30 minutes) and 118 dergrees Fahrenheit (@15 minutes). Anodizing, powder coating, chrome, nickel, paint, and most other coatings will not be removed as long as they do not contain oxides. EVAPO-RUST^TM will not harm lead or solder points. To de-rust the inside of a bore, plug one end and completely fill bore with EVAPO-RUST^TM. Let sit for approximately 30-45 minutes and pour out. Oil with CarWell CP90 or other CPC.

CLEANING VS. DE-RUSTING
EVAPO-RUST^TM has a surfactant to aid in penetrating oils and dirt. However, surface contaminants do slow the process. The soils must be penetrated before EVAPO-RUST^TM can come in contact with the rust. Additionally, heavy soil residue can shorten the life of EVAPO-RUST^TM . Oils, greases and cosmoline should be removed prior to de-rusting. Use a clean water rinse on the newly cleaned part to keep from raising or lowering the pH of EVAPO-RUST from other products. Cleaning the part prior to soaking in EVAPO-RUST^TM will also help in the disposal of the spent product.

RUST INHIBITION/PAINTING/COATING
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 such as CarWell CP90; or 3) Wash and rinse the item and dip back into EVAPO-RUST^TM, remove and let dry. EVAPO-RUST^TM 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 such as CarWell CP90.

TRANSPORTATION/DISPOSAL
EVAPO-RUST^TM 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^TM 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.

LIFE/CAPACITY/STORAGE
EVAPO-RUST^TM 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^TM 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^TM. The black is carbon from the steel. Generally high carbon steel is used in making items that are flexible (e.g. springs, saw blades, etc.). 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^TM is spent when the specific gravity reaches 1.08, it is pitch black, and no longer performs.
