How to Care for Your Adoorn

Mailbox Guide / Care & Maintenance
Updated · July 9, 2026 · Adoorn Team
Beautiful is the easy part.
Care in minutes
Four moves keep every Adoorn piece looking new.
Mailbox, wall mount, package box, numbers, and posts, all the same routine.
  1. Clean. Mild soap and water with a soft cloth, then dry it off. Skip alcohol-based cleaners, which can strip the powder-coat finish over time.
  2. Protect. A coat of clear car wax on the exterior every 4–6 months keeps the color and finish looking new.
  3. Touch up. If bare metal ever gets exposed (a deep scratch or ding), dab on a protective paint like Rust-Oleum® promptly so it never gets a chance to rust.
  4. Locks (locking models). Twice a year, apply a lubricant such as Tri-Flow to the interior of the lock to keep it turning smoothly. Keep a spare key on hand; replacement keys are available if you ever need one.
That’s the whole routine. No sealing, no annual service. A few minutes of care a couple of times a year keeps every piece looking new.
02 Why care is this simple

Well-made pieces reward a little upkeep.

With the recommended care, the finish stands up beautifully. Every Adoorn mailbox, wall mount, and package box is built from heavy-duty galvanized steel with stainless steel hinges and a rust-resistant powder-coat finish. Weatherproof and worry-proof, and built to meet USPS standards.

Give it the simple routine below (a wipe, an occasional wax, and a twice-a-year lock lube on locking models) and it holds its color and finish for years. It’s a well-made product that rewards a little upkeep: built to last, and easy to keep looking new.

03 Care by product

The specifics, product by product.

Adoorn Post Mount mailbox, angled studio shot
Post Mount, Non-Locking + Locking (Small & Large)
The quick care routine is all it needs.
Wipe the flag and hinge area, and keep the outgoing-mail area clear. Locking model? See Lock care below. Extra holes on the bottom? Adoorn’s mounting-hole patterns are configured to fit both the Adoorn post and other standard posts, so you may have holes you don’t use, see troubleshooting for the quick hole-plug fix.

Adoorn 4-inch Mailbox Numbers in silver
4" Address Numbers & 6" House Numbers
Solid aluminum. They won’t rust.
Wipe with mild soap and water. On coastal or oceanfront homes, rinse them quarterly to prevent surface pitting. One note: the adhesive is permanent, so place them where you want them the first time; don’t reposition after day one.
Adoorn 51-inch In-Ground Post in black
In-Ground Post & other posts/plates
Same routine, plus watch the ground line.
The same routine, plus one habit: touch up nicks at the ground line with a protective paint like Rust-Oleum®. String-trimmer scuffs at the base are the #1 spot bare metal shows up, so catch those early.

04 Season by season

A little more care when the weather asks for it.

Winter
Rinse road salt and ice-melt off the mailbox and post when you get a mild day. Salt is the one thing that works on any finish over time.
Coastal / salt air
Give everything a quick freshwater rinse quarterly (including the aluminum numbers) to keep salt from pitting the surface.
Full sun
The powder-coat finish is UV-resistant. The special step in sun-heavy locations is the twice-yearly coat of clear car wax; it keeps the color deep and the finish from dulling.
05 A few things to avoid

The wrong tool is the usual culprit.

Most damage comes from the wrong tool. Keep these off your Adoorn:

  • No abrasive pads, steel wool, or scouring powders. They scratch the finish.
  • No harsh solvents, bleach, or alcohol-based cleaners. They can strip the powder-coat finish.
  • No close-range pressure washing.
  • Never drill into the mailbox. It exposes untreated metal and voids the warranty. If you’re mounting, drill the post, not the box.
06 Quick troubleshooting

Symptom, then fix.

Rust spot or exposed metal Dab on a protective paint like Rust-Oleum® to seal it before it spreads.
Stiff or sticky lock Apply Tri-Flow to the interior of the lock. Keep a spare key on hand (replacements available).
Extra or unused holes on the bottom of the mailbox (Post Mount mailboxes, Non-Locking and Locking Small & Large.) Our Adoorn mailbox hole patterns are configured to work with both the Adoorn mailbox and other standard mailboxes on the market. We recommend purchasing a standard 5/16" hole plug if you’re having an issue with any of the unused holes.
Scuffs at the post’s ground line Dab on a protective paint like Rust-Oleum® to seal the scuff before rust can creep in. String-trimmer nicks at the base are the #1 spot to watch.

08 Frequently asked

Care questions, answered.

How do I clean an Adoorn mailbox?

How do I take care of the lock?
On locking models, apply a lubricant such as Tri-Flow to the interior of the lock twice a year to keep it turning smoothly, and keep a spare key on hand. Replacement keys are available if you need one.
Do Adoorn mailboxes rust?
They’re built to resist it: heavy-duty galvanized steel with a rust-resistant powder-coat finish. If bare metal ever gets exposed by a deep scratch or ding, touch it up promptly and it stays rust-free.
How do I care for it in winter or on the coast?
In winter, rinse road salt and ice-melt off when you can. In coastal salt air, give everything (including the aluminum numbers) a freshwater rinse about quarterly to prevent surface pitting.
