Treat your water- Though this is not always practical, softening hard water can do much to
reduce deposits. There are certain filters that can be installed to remove corrosive elements.
If you are not sure of the proper water treatment, call a treatment specialist.
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.
