FAQs About Evapo-Rust - The Super Safe Rust Remover
A product of extensive research, Evapo-Rust rust remover is an environmentally safe water based product that has been proven to make even deep rust disappear in minutes, without any scrubbing.
It’s so easy to use, anyone can restore their rusted tools, auto parts, even firearms to like-new condition. One gallon de-rusts up to 300 pounds (136kg) of steel.
Best of all, Evapo-Rust is safe to use. It’s non-toxic, non-corrosive, non-flammable, and contains no acids, alkalis or petroleum solvents. Evapo-Rust is also biodegradable.
Rust Removal Has Never Been Easier!
- Pour into a container a sufficient amount of Evapo-Rust to completely cover the rusted object.
- Immerse the rusted object into the Evapo-Rust solution for 30 minutes (light rust) up to overnight (heavy rust).
- Rinse item with water. If deep rust remains in puts, re-immerse in Evapo-Rust.
Q. How does Evapo-Rust work?
A. Evapo-Rust uses “selective chelation”, a process in which a large synthetic molecule forms a bond with metals and holds them in solutions. The active ingredient in Evapo-Rust bonds exclusively to the iron in ironoxide – not in steel.
Q. Do parts have to be completely clean before treatment?
A. No. Evapo-Rust contains detergents which can penetrate dirt and oil. However, surface contaminants do slow the process. The soils must be penetrated before EVAPO-RUST can come in contact with the rust underneath. Soil residue will also shorten the life of EVAPO-RUST. Heavy greases and cosmoline should be removed prior to de-rusting.
Q. Will Evapo-Rust remove bluing and other oxide finishes?
A. Yes, in about 30 minutes. Anodising will not be removed. Powder coating and paint will not be removed as long as the paints do not contain oxides.
Q. Can I clean brass, copper and aluminium with Evapo-Rust?
A. No, it will not clean (or damage) any of these metals. It will not harm plastic, clothing or glass either.
Q. I get a black film on some parts after using Evapo-Rust. What is it and how do I remove it?
A. The black is carbon from the steel. Generally high carbon steel is used in making items that are flexible (e.g. springs, saw blades) High carbon steel and tool alloy steel items when de-rusted will have a darker appearance. Much of the carbon can be removed simply by wiping with a cloth.
Q. Can I de-rust by spraying Evapo-Rust on the rusted area?
A. No. Evapo-Rust only works in liquid form, since the water in the solution will evaporate when sprayed. However, it can be sprayed on unrusted steel as a rust preventative.
Q. How can I use Evapo-Rust on a surface too large to soak?
A. Place a paper towel soaked in Evapo-Rust over the rusted area. Cover the paper towel with plastic wrap and tape the wrap down to prevent moisture from escaping. Remove in 24 hours and rinse with water.
Q. How long does Evapo-Rust last?
A. One gallon of Evapo-Rust will remove moderate rust from 300 pounds (136kg) of steel. If any of the bath evaporates, simply replace with fresh tap water.
Q. How do I know when the bath is spent?
A. The bath will turn completely black and will not remove rust.
Q. How do I dispose of the spent solution?
A. Pure Evapo-Rust can be safely poured into the city sewer. When the solution is spent, only the iron content will dictate the disposal method.
Q. How do I protect parts against rusting?
A. De-rusting with Evapo-Rust will provide 10-14 days of rust inhibition, depending on humidity. You can spray it on unrusted steel to prevent rust from forming on your tools, hardware and garden equipment. Its water-based, non-toxic formula inhibits rust from forming on all ferrous metals.
