How to clean rust stains from "stainless" steel


Stainless steel comes in several grades of purity. All grades contain some iron, among other metals such as chromium, manganese, silicon, carbon and often nickel and molybdenum.

It is the inclusion of iron that gives rise to rust staining of the "stainless" steel. This happens when the protective layer of chromium oxide is damaged or there was not enough chromium included in the alloy.

There are over 150 grades of stainless steel and some are more prone to rust staining than others. Generally, the higher the chromium content, the less likely the steel will rust. However, given enough time, some rust will appear on most stainless steel

What makes stainless steel "stainless"?

When the chromium in stainless steel is exposed to oxygen in the atmosphere it forms a thin and invisible layer of "chromium oxide". It is this invisible layer, which covers the entire surface, gives stainless steel its ability to resist stains and rust. But if this layer is damaged, rust will form on the surface at the location of the damage.


How to use Benz Oxy Cleanze rust removal gel to clean rust stains from stainless steel

The before and after photos (below) are of stainless steel handrails and bollards that were covered with rust stains.

This may have been caused by contamination from mild steel during fabrication, contamination during use, or by using a low grade of stainless steel.

Application is simple: We brushed on Benz Oxy Cleanze and left it to work for 2 hours at 4 ℃. We lightly rubbed the surface with a rag and then rinsed.

Quick tip: Sometimes, to be fully effective, Oxy Cleanze may require leaving longer and may require a second application.
