cleaning periodically especially in agressive environments such as coastal areas or swimming pools, is essential.

What is tea staining?
Tea staining can be defined as: discolouration of the surface of stainless steel that does not affect the structural
integrity or the longevity of the material.
Tea staining occurs most commonly within about 5 kilometres from the surf and becomes progressively worse
closer to the marine source. However, wind exposure, pollution levels and higher temperatures can create
environments where tea staining might occur 20 kilometres or more from the sea water. These same factors also
increase corrosion rates of alternative materials.
