Whether you are collecting katana or practicing swords, you should take measures to protect your swords from rusting.
Although most people are familiar with the basic appearance of rust, few people know its actual composition and properties.
Scientifically speaking, rust is iron oxide (chemical Fe2O3) produced by the oxidation of iron. When iron is exposed to water, oxygen, or sunlight, certain chemical reactions occur in a process called oxidation, which leads to rust. Can clean and remove slight rust. However, if left unresolved, it will actually corrode the metal, causing permanent damage to the blade.
I know what you are thinking: My sword is made of steel, not iron. How can it rust? Due to the presence of iron, even steel swords are prone to rust. Steel is an alloy containing iron; therefore, it can also rust. Iron traces buried deep in steel react the same way to moisture, light and oxygen.
One of the most important tips to protect your sword from rusting is to keep it dry. Water divides into rust to provide a perfect environment for growth. Therefore, by keeping the sword dry, you will naturally protect it from rust.
Clean after treatment
Try to develop the habit of cleaning the sword after use. Wipe the blade carefully with a cordless cloth to remove all dust, dirt, debris and fingerprints.
For a deeper and more thorough cleaning, you may need to use a special sword cleaning product.
Wax or oil
In addition to cleaning your sword, you should also apply wax or oil to the blade to further prevent it from rusting. If you ask ten different collectors which wax or oil to use, you may get ten different answers. That being said, some of the most popular options include 100% mineral oil or gun oil. No matter which product you choose, please apply a small amount of product to the hidden area of the blade and wait for its reaction to test in advance.
Store in a dry environment
You can also store the sword in a climate-controlled facility to prevent it from rusting. More specifically, store your sword in an environment with a relative humidity of 40-50%. Humidity is a measure of the amount of water vapor in the air. When the relative humidity exceeds 60%, it indicates that there is too much water vapor, otherwise it may cause rust and corrosion.
