The myth is that stainless steel does not rust but unfortunately that is not true, stainless steel is susceptible to rusting.
There are two different metals, active and passive. Active metals such as iron and steel easily corrode showing yellow or orange rust. Stainless steel is referred to as passive because it contains other metals including chromium. There are two grades of stainless, 304 and 316L. The 316L contains additional molybdenum and resists corrosion in environments rich in salt and chloride, thus known as “marine grade”
stainless steel. However, the addition of molybdenum only delays corrosion, it does not stop it. Regardless whether you use 304 or 316Lstainless steel cabinetry or appliances for your outdoor area, they require maintenance.
Chromium creates an invisible shield and the cabinets or appliances remain corrosion resistant until this shield is broken down. Three things that can cause this to happen is as follows:
- Mechanical abrasion – steel pads, wire brushes and scrapers will scratch the steel surface.
- Water – depending on where you live, your water can be hard or soft. Hard water may leave spots and when heated leave deposits behind. These can break down this layer leaving the stainless steel to rust. Remove deposits from food preparation.
- Chlorides – are found everywhere including in water, food and table salt. Household and industrial cleaners contain some of the worst chlorides.
Tips for Success
How quickly your outdoor stainless steel cabinets and appliances will rust depends on the type of stainless steel and how well you maintain them. The following are cleaning tips to reduce the risk of rusting and corrosion:
- Use only alkaline, alkaline-chlorinated or non-chloride cleaners.
- Avoid hydrochloric acid (muriatic acid) on your stainless steel.
- Always use a non-abrasive cleaning tool such as a soft cloth or plastic scouring pad.
- Avoid steel pads, wire brushes, scrapers.
- Always clean in the direction of the polishing marks by locating the lines or grain and scrub in a motion parallel to them.
- If you do end up using a chlorinated cleaner, be sure to rinse thoroughly and dry the surface immediately.
- Air dry your equipment.
Finally, it is important to note that stainless steel is NOT stain proof, it is stain less.
