1. What is Evapo-Rust Rust Remover?
Evapo-Rust is a non-hazardous rust remover that uses selective chelation. During this process, a large synthetic molecule forms a bond with metals and holds them in solution. This bond forms only with the iron in iron oxide (rust), not in steel. Evapo-Rust rust remover is not powerful enough to remove iron from steel.


2. Is Evapo-Rust safe to use?
Yes! Evapo-Rust rust remover is non-toxic, non-flammable and non-corrosive. It contains no acids, alkalis, petroleum solvents or VOCs. It is also biodegradable.


3. What is the difference between Evapo-Rust Rust Remover and Rust Converter?
Rust Converter will convert rust into an inert surface and needs to be brushed or sprayed on. Evapo-Rust will remove rust, but the rusted object needs to be soaked in it.


4. Does Evapo-Rust have a shelf life?
No. The shelf life is indefinite. Evapo-Rust can be used repeatedly until it no longer removes rust. If any of the bath evaporates, simply refill it with fresh tap water. The bath is spent when it turns completely black and will not remove rust.


5. What objects can Evapo-Rust be used on?
Evapo-Rust can be used with any rusted (iron oxide) object that can be immersed in it. It will not harm rubber, plastic, PVC, viton, most paints or metals.

6. What if the object is too large to be immersed in Evapo-Rust?
Soak a smooth paper towel or fake chamois with Evapo-Rust and place it over the rusted area. Press firmly and evenly. Cover the area with plastic and tape it down so the water in the solution can’t evaporate. Remove it in 24 hours and rinse the surface with water.


7. How should you store Evapo-Rust?
Evapo-Rust should be stored in a cool, dry place away from extreme temperatures. Keep the bath covered to keep out debris, but not in an airtight container.


8. What Personal Protective Equipment is recommended when using Evapo-Rust?
No Personal Protective Equipment is typically required when using Evapo-Rust.


9. What is the optimal temperature at which Evapo-Rust should be used?
Evapo-Rust should be used at a bath temperature above 60ºF and room temperature at or above 68ºF. It is a water based product, so the speed of the process will slow down as temperature decreases.


10. What preparation is needed before Evapo-Rust is applied?
Remove large rust and scale particles with a wire brush or sandpaper. Then clean the surface thoroughly to remove dirt, dust and grease. Evapo-Rust contains detergents that penetrate oil and dirt, but this slows the rust removal process. The bath will also last longer if it is free from these contaminants.

11. How should Evapo-Rust be applied?
Pour enough Evapo-Rust into a container that can accommodate the rusted object. Immerse the rusted object and let it soak for 30 minutes to 24 hours. The soak time depends upon the severity of the rust and the temperature. When the rust is gone, rinse the object with water. You can then proceed to paint or coat the object if you choose to do so. Another option is to dip the object in Evaporust and let it dry. This will inhibit rust for up to two weeks.


12. Can a sprayer be used to apply Evapo-Rust?
No. If Evapo-Rust is sprayed, the water in the solution will evaporate before it can remove rust.


13. How should Evapo-Rust be disposed of?
If used with clean steel, the bath should only consist of water and chelated iron. If the steel was not clean, then oil, grease and other substances may be present. Spent Evapo-Rust should be disposed of in accordance with all federal, state and local regulations.


14. Will Evapo-Rust remove corrosion from brass, copper or aluminum?
No. Evapo-Rust will only remove rust (iron oxide).


15. Are there any metals that Evapo-Rust should not be used with?
Evapo-Rust should not be used with magnesium or magnesium alloys.

16. Will Evapo-Rust have any effect on coatings such as bluing or paint?
Evapo-Rust will remove coatings such as bluing and zinc phosphate, but it will not remove anodizing, powder coating, paint and most other coatings as long as they do not contain oxides.


17. After I use Evapo-Rust, there is a black film on the object. What is this?
The black film comes from carbon in the steel. This is common with high carbon steel found in flexible items such as saw blades and can usually be removed by wiping the object with a cloth.
