Why Stainless Steel Kitchen Equipment Rust?

March 08, 2024

Stainless steel kitchen equipment itself is a kind of metal that is not easy to rust, but the fact that stainless steel kitchen equipment is not easy to rust does not mean that it will not rust. Depending on the conditions of use or the environment in which it is used, it can also be contaminated and rusted. Especially in the catering industry, the kitchen belongs to an environment of high temperature, high humidity, and high oil. So what exactly causes stainless steel kitchen appliances to rust? And what can we do to avoid this?

Main causes of rust:

● Exposure to Chlorides: Stainless steel can rust if exposed to chlorides, such as those found in salt, bleach, or certain cleaning products. These chlorides can break down the protective layer of chromium oxide on the surface of the steel, leading to rust formation.

● Scratches and AbrasionsScratches on the surface of stainless steel can provide pathways for moisture and contaminants to penetrate and reach the underlying metal. This can accelerate corrosion and rusting.

● Poor Cleaning Practices: Improper cleaning techniques or the use of harsh chemicals can damage the protective layer of stainless steel, making it more susceptible to corrosion and rust over time.

● Exposure to Acids: Stainless steel can corrode when exposed to strong acids, such as those found in certain foods (e.g., citrus fruits) or cleaning agents. Acidic substances can degrade the protective layer of chromium oxide and promote rust formation.

● High Temperatures: Prolonged exposure to high temperatures, such as during cooking or sterilization processes, can compromise the corrosion resistance of stainless steel, especially if it lacks sufficient chromium content.

Rusting of stainless steel appliances is usually caused by the attachment, accumulation, and attachment of components in floating iron dust or salts from harmful atmospheric gases in the sea breeze. These attachments will gradually build up and become fixed by moisture. This will destroy the non-oxidizing film on the surface of stainless steel kitchen equipment and cookware and prevent the regeneration of the film. As a result, stainless steel kitchenware will begin to rust, but with regular maintenance, the pristine beauty of stainless steel kitchenware can be maintained.

Measures to prevent stainless steel kitchen equipment from rusting:

● Proper Cleaning and Maintenance: Use mild detergents and non-abrasive cleaning tools to clean stainless steel surfaces. Avoid using harsh chemicals or abrasive cleaners that can damage the protective layer. Rinse equipment thoroughly after cleaning to remove any residue.

● Regular Inspection: Periodically inspect stainless steel equipment and cookware for signs of damage, such as scratches or pitting. Promptly repair or replace any damaged items to prevent further corrosion.

● Avoid Exposure to Chlorides: Minimize exposure to chlorides by avoiding contact with salt water, salty foods, or cleaning products containing chlorine. If exposure occurs, rinse the affected surfaces thoroughly with clean water.

● Protective Coatings: Consider applying protective coatings or treatments specifically designed for stainless steel to enhance its corrosion resistance and prevent rust formation. These coatings can provide an additional barrier against environmental factors.

● Avoid Acidic Foods and Cleaners: Be cautious when using acidic foods or cleaning agents on stainless steel surfaces. If necessary, neutralize acidic spills promptly and rinse the area thoroughly with water to prevent corrosion.

Proper Storage: Store stainless steel equipment and cookware in a clean, dry environment to prevent moisture buildup and corrosion. Use appropriate storage racks or shelves to avoid scratches and damage during storage.

● Regular Maintenance Schedule: Implement a regular maintenance schedule for cleaning and inspecting stainless steel equipment and cookware. This helps identify and address any issues before they escalate into larger problems.

By following these preventive measures and maintaining a proactive approach to cleaning and maintenance, you can effectively prevent contamination and rusting in stainless steel kitchen equipment and cookware, ensuring their longevity and performance in commercial kitchen settings.
