Monarch Metal How-To: Cleaning & Maintaining Stainless Steel
While it’s a common assumption that stainless steel can go long periods of time without a proper cleaning, this type of metal truly needs regular TLC. Although stainless steel has a higher resistance to exposure than other metals, it can become discolored and even corroded over time. This is usually due to a compromise in its passivity layer.
Any stainless steel that contains 12-30% chromium forms a passivity layer that acts as a shield against corrosion. Made of chromium oxide, this layer blocks oxygen diffusion (movement) to the steel’s surface and keeps corrosion from spreading both internally and externally.
Regular cleaning and maintenance is, by far, the smartest way to keep the passivity layer intact and prevent corrosion. Luckily, stainless steel is relatively easy to maintain, so you’re not in for a frustrating job that’s going to be time-consuming.
