Without regular cleaning and maintenance discolouration of the surface of the stainless steel by corrosion (tea staining) can occur.

How to reduce the risk of tea staining

• Absence of corrosives – especially salt, chlorine, cleaning acids etc.
• Atmospheric Conditions – lower temperatures and low humidity are better.
• Surface orientation – Open exposure to rain washing is better
• Surface Finish – In general a smoother finish is better. where practical mirror polish finish may perform better than a brushed finish.
• Chemical cleanliness or passivation of the surface improves corrosion resistance
• Appropriate grade selection for conditions
• Regular Maintenance to limit the accumulation of corrosives

Stainless steel cleaning schedule

The frequency of cleaning will vary depending on environmental factors i.e. proximity to the ocean, atmospheric and urban conditions. Below is intended as a guide and should be varied as required. We recommend using peek stainless steel polish for maintenance.
