What is tea staining?

* Tea is a type of atmospheric corrosion that may appear on the surface of stainless steel balustrades.

* Does not rust and will not affect the structural integrity.

* It is common in coastal areas (within 5 km) of whee salt allowed to accumulate on the surface of the stainless steel.

* Steel corrosion of the steel surface can also occur by contact with aggressive cleaning acids (e.g. hydrochloric acid) or carbon steel (via aerosol grinding, improper use of discs or welding fin not cleaned properly), which is not the tea stain.

How to remove it -

* If you have a problem with tea stains, it is important to act quickly. The stain will get worse and become repeatedly if left too long before cleaning.
* If the finish of your furniture is satin brushed then most stains can be cleaned using a standard household sponge. DO NOT USE steel wool.
* For the connections of mirror polished or particularly bad spots mild acid cleaning should be used. Any of phosphoric acid can be applied with a brush, allowed to react for approximately 30-60 minutes (or until the spots disappear) and washed with clean water.
