Cleaning and maintenance of stainless steel.

Stainless steel is a highly resistant and beautiful material, which is easy to conserve. However, it does require maintenance. For this, it is necessary to follow some minimum recommendations during its storage, manipulation and use. Correct cleaning preserves its original characteristics, especially its resistance to corrosion.
 

During cleaning, it is important to clean the contaminating agents, which are present in the atmosphere. This is particularly the case in industrial places or close to a marine environment, as these areas can cause localized corrosion if not efficiently maintained.
 

A damp cloth or chamois leather cloth should be used to eliminate the dirt on the surface. In the case of extra dirt, gentle detergents suitable for domestic use should be applied with non-abrasive scrubbers or nylon brushes (no metal scrubbers). After cleaning, wipe away the residue with water and dry the surface. The recommended frequency is every 6 - 12 months for moderate dirt and 3 - 6 months for heavy dirt or for the following situation:
Marine atmosphere - Industrial contaminated areas - salt from road gritting - dirt from traffic.
 

Cleaning agents that contain chlorine or bleach should not be used.
