The word “stainless” in stainless steel can be misleading. Stainless steel is actually corrosion resistant, a quality it derives from the high percentage of chromium present in its make-up.
Chromium is an element that, when exposed to oxidizing materials such as caustics, water and air, forms a thin impervious oxide layer that stops further corrosion.
Fascinating fact about chromium oxide in your stainless steel fixtures—when a stain is properly cleaned and dried, that layer of chromium oxide will reform on its own in a few days. It’s like the Wolverine* of metals.
One of the biggest reasons customers end up with rust on their stainless steel fixtures is improper cleaning and care. However, that’s easy to solve and best of all, it does not require expensive specialty cleaners.
Cleaning Products You Should Be Using
- Hand dishwashing liquid/soft water solution
- Mild soap/soft water solution
- CresClean™ cleaner and polish, for removal of tough stains
- 3M™ Stainless Steel Cleaner, for removal of tough stains
- White vinegar (for brightening and removing hard water deposits)
- Club soda
Cleaning Products That Should Never Be Used
- Cleaners containing any abrasive particles (Comet®, Ajax®, Bon Ami®)
- Harsh chemicals containing strong acidic or alkaline materials
- Chlorinated cleansers, sanitizers or bleach of any kind
Other Ways to Protect Against Corrosion
- Avoid leaving any object made of steel or metal on the stainless steel surface (hairpins, paper clips, aerosol cans, etc.)
- Avoid letting seawater or excessively hard water sit on the surface
- Avoid leaving salt or salty foods on the surface
- Fix any scratches in the surface (debris may collect in these preventing the surface from “healing”)
- Do not leave water to evaporate as that may result in hard water stains
To remove stubborn stains or scratches, use a synthetic, general-purpose abrasive pad such as Scotch-Brite™ to apply stainless steel cleaner/polish. Carefully rub out the spot by rubbing in the direction of the grain. (Exception: High-polish stainless steel surfaces should never come in contact with any abrasive brush, cloth or cleaning agent.)
To remove dirt and debris, apply one of the mild cleaners mentioned above using a soft cloth. Rinse the surface thoroughly with clean water followed by wiping dry with a soft, clean cloth and stainless steel cleaner/polish.
