Keep your equipment clean- 

Use proper cleaners at recommended strength.  Clean frequently 

to avoid build-up of hard stubborn stains. 

Rinse thoroughly - 

If chlorinated cleaners are used, you must rinse and wipe dry immediately.  

The sooner you wipe off standing water, the better.  After wiping the unit down, allow it to air 

dry. The oxygen helps maintain the stainless steels passivity film. 

Never use hydrochloric acid (muriatic acid) on stainless steel.

Passive Film Breakdown 

 

Corrosion on metals is everywhere.  We recognize it quickly on iron and steel as 

unsightly yellow/ orange rust.  Such metals are called “active” because they actively 

corrode in the natural environment. 

 

Contrary to popular belief, Stainless Steels are susceptible to rusting. The first signs are 

on the microscopic level.  If you were to look at them under a microscope or through a 

magnifying glass, you would see small pits and cracks will grow and deepen while all the 

time exuding unsightly, red-orange rust. More severe and visible cracking can also take 

place. 

 

Stainless steels are protected by a thin layer of chromium oxide, and it important to 

keep that film of chromium oxide intact. If the passive film of your stainless steel has 

been broken, you are subject to corrosion and rust. The integrity of the chromium oxide 

can be compromised by: 

-

 

Mechanical abrasion

 from steel pads, brushes, and scrapers. 

-

 

Hard Water 

leaves mineral deposits behind that, if left to dry will break down the 

passive layer and rust your stainless steel. 

-

 

Chlorides

 are in water, food, and table salt, but most prominently in cleaning agents.
