Stainless steelbetter known as Inox, is an iron alloy in which the resistance to corrosion is increased through the addition of chrome and nickel. The principle involves the protection of the outside surface by chromium oxide and nickel oxide molecules. These molecules are uch bigger than the underlying iron atoms, which prevents the latter from combining with oxygen to form iron oxides – better known as rust. This passive layer protects the precious steel and is self-renewing. In order to obtain a chromium-and nickel oxide skin that is as pure and homogeneous as possible, and therefore optimally corrosion-resistant, the standard Royal Botania frames are etched and rinsed with demineralised water after which a passive layer is formed by natural oxidation. Chlorine is the biggest enemy of stainless steel and can cause a form of corrosion known as “pitting”. Contamination by chlorides or rusting particles can penetrate the passive layer and cause corrosion in certain places. This is especially important when near the sea, because of course sea salt is sodium chloride. It is necessary to give the metal as smooth a surface as possible in order to give it an even greater resistance to corrosion. This is because if the surface is smooth, there is less chance for contamination to take hold on the metal surface, thus reducing possible corrosion.

Stainless Steel

Since stainless steel is not corrosion resistant by definition, it is advisable to clean the furniture regularly with clean water and soft soap. This minimizes the contamination of the surface, including by metal particles known as airborne rust. In areas near the coast or close to industrial plants that produce an increased concentration of chlorides or sulphur dioxides, cleaning to remove deposits is extremely important. Inside use causes annoying stains, usually through fingerprints.

In areas with a high corrosive impact (coastal areas, industrial areas) or the influence of thawing salt, smoke emissions and environmental pollution, more regular cleaning is needed (ca 3-4 times a year) than in areas where such influences are not so great or not present at all (ca 1-2 times a year). The overall principle is that cleaning should be done before the deposit of high-level contamination.
