Packing up your boat, furniture, coins and jewelry, ATV, bicycles, electronics, tractor, firearms, RV, travel trailer or other items for long-term storage? You can’t afford to ignore the potential for rust and corrosion. This is particularly true if the space in which you’re storing your items lacks climate control. Sometimes the effects of corrosion can be mitigated after the fact, but it’s always better to prevent rust if you can.
Most people recognize that rust is one process of corrosion that pertains specifically to metals made of iron and its alloys (such as steel). When these elements come into contact with oxygen and water (or even just moisture), rust will begin to form. How fast it takes over depends on other environmental factors, such as temperature fluctuations, the presence of salt in the air or even proximity to other types of metals.
Rust that forms on iron or steel can be porous, allowing water and oxygen to reach the underlying surface of an item and penetrate deeper. Corrosion of other types of metals (aluminum or copper, for instance) tends to result in a tight film of oxide that protects the other layers from deeper corrosion. But it depends on the chemical makeup of the metal and the construction of the item.
