Maintenance Guide

Powder Coated Products

The standard range of mailboxes from The Safety Letterbox Company is crafted from aluminum or zintec steel. We finish these mailboxes with a polyester powder-coated paint for durability and appearance. To maintain the mailbox’s appearance, wash it with a wet soapy cloth 3-4 times a year. Regular cleaning helps prevent corrosive damage that can tarnish the mailbox’s look and reduce its weather resistance.

Neglecting this maintenance may lead to significant deterioration over time. Consequently, routine care ensures the mailbox remains attractive and functional. Additionally, proper upkeep prolongs its lifespan and effectiveness.

Stainless Steel

The stainless steel mailboxes supplied by The Safety Letterbox Company must be maintained in order to not get rust-like tempering. It is recommended that the surface of stainless steel should be cleaned on a regular basis and additionally wiped with an acid-free oil at least 3-4 times a year.

If the stainless steel is not cleaned then tempering may occur, this can be removed using a very fine abrasive agent that will restore the material back to a previous state. However, it is important that the box is cleaned afterwards on a regular basis and oiled multiple times a year.

Under no circumstances are steel wool, steel brushes or similar items to be used for cleaning as they damage the protective surface and therefore enable a rust film to form due to abrasion.

Locks

Mailbox locks should be lubricated 1-2 times a year using a lock spray. This helps prevent general wear and reduces jarring sounds.

Regular lubrication ensures the lock operates smoothly and avoids potential issues. If the mailbox lock freezes during winter, apply lock oil to free it.

This helps maintain the lock’s functionality in cold temperatures. Additionally, addressing freezing issues promptly prevents long-term damage. Routine maintenance keeps the lock in good working condition and ensures reliable performance throughout the year. Consequently, proper care extends the lifespan of your mailbox lock.

Filiform Corrosion

In cases of mailboxes being installed in a coastal location with corrosive air (industrial waste gases), ‘filiform corrosion’ can arise. If this issue is relevant to the area that the mailboxes are to be installed in, an alternative such as adding a clear lacquer finish to the mailbox during manufacturing should be planned.

Ask your advisor from The Safety Letterbox Company regarding this. Inadequate cleaning and care of the surfaces as well as scratches can favour the spread of filiform corrosion.
NB: For mailboxes that contain multiple materials, each part must be maintained as described above.
