Rust can cause a variety of problems such as brittleness which is dangerous. Learn these simple tricks to stop rust in its tracks and send it into retreat.
Stop Rust Before It Starts
Rust begins when iron reacts with oxygen in the presence of water, salt water, acids, or other harsh chemicals. As the iron oxide flakes off the metal surface, it exposes fresh iron molecules, and the rusting process continues. Eventually, large areas of rust form that may cause the entire metal structure to disintegrate.
Keep It Clean and Dry
When it comes to rust, water is enemy number one because it’s the oxygen in water molecules that combines with iron to form iron oxide. That’s why metals left outdoors, such as cars, gates, lawn furniture, or tanks, are more likely to rust. If the object is in a humid indoor environment, such as a garage or basement, install a dehumidifier. Any mud or dirt adhering to the surface can hold water, so it’s important to keep metals clean and dry to stop rust before it starts.
Scratches or cracks in the metal expose more metal and hold water, allowing it to remain in contact with the iron. Friction scratching can be avoided by taking special care when transporting, repairing, and storing metal parts/tools.
Apply a Protective Coating
RUST-BLOCK™ is a revolutionary water-based rust inhibitor that works to help stop rust on all ferrous metals and is ideal for home or shop use. Use it to protect your tools, auto parts, hardware, gardening gear, and more. Also, it is ideal for industrial use. When you are ready to remove the invisible coating, rinse it away with warm water. Then, your item is ready to paint, primer, or oil.
RUST-BLOCK™ is available in aerosol or trigger sprayer, protects from rust for up to 1 year, and is:
- No foul odors or strong fumes
- Indoor use only
Use Stainless Steel
Stainless steel alloys contain iron, but it resists rust because it also contains a high chromium percentage, which is even more reactive than iron. The chromium in the alloy oxidizes quickly to form a protective layer of chromium oxide on the metal surface, preventing oxygen from reaching the underlying steel.
Use Galvanized Metal
Galvanization is a process used to preserve steel rust-free for many years. In the galvanizing process, a piece of steel is coated with liquid zinc. The zinc protects the steel in three different ways:
- the zinc coating acts as a barrier preventing oxygen and water from reaching the steel
- if the coating is scratched off, the zinc continues to protect nearby areas of the metal through cathodic protection
- zinc is highly reactive to oxygen and quickly forms a protective coating of zinc oxide, which prevents the iron from further oxidation.
Because rust spreads quickly, it’s important to scrape it off as soon as it appears. Then, scrub with warm water and soap and apply RUST-BLOCK™ to prevent further oxidation. If necessary, apply a new coat of paint to the area.
RUST-BLOCK™ stops rust before it begins. It’s safe and easy to use. Do you follow us on social media? Check out our Facebook to see all the projects people have done using Evapo-Rust®.
