NEVER use harsh cloths / pads or steelo wool. Regular washing using a CLEAN soft cloth in warm water with detergent and rinsing with clean cold water or general household stainless steel cleaner (even WD40) is recommended every 3 months.

A stainless steel cleaner and preserver is highly recommended for marine / coastal environments which is available from The Letter Box Shop.

Other products suitable to use are Lanolin based corrosion inhibitors such as Pro Lan and Lanoguard which can be purchased from most hardware stores or marine boating stores.

The Letterbox face panels and plaques come with a N4 finish (Brushed) that can be easily scratched during installation and is recommended that care is used when handling and installing to avoid any surface scratches as The Letter Box Shop will NOT class this as defect for a return.
