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
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.
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.
We hope this information is helpful and sincerely wish you great success in your soft washing business,

It's a free resource for people wanting to learn about the soft washing industry, to expand an existing business, or build a new business.
Soft washing reduces, or even eliminates, the need to use high-pressure washing.
Instead, once the build up of algae, lichen, fungus and mould – the root causes of properties looking "dirty" – has been treated, the natural "self-cleansing" of sun, rain and wind removes the surface residue through time.
By educating the cleaning trade and public about soft washing we are helping develop an industry that offers sustainable treatments to clean and maintain exterior hard surfaces.

The free guide shows you – step by step – how to easily, quickly, and accurately create softwash business quotes.
This saves you time, is a highly professional approach, and increases your chances of winning new contracts.
