Why maintenance matters. Regular cleaning is the single most important factor in the long-term appearance and durability of a powder-coated finish. Following this guide keeps your finish looking its best and is a condition of finish warranty cover under our Warranty Policy.

1. About Your Finish

Your PO Box Designs product is powder-coated by a Dulux Accredited Powder Coater to AS 3715. Powder coating is a durable, decorative and protective finish, but like all architectural finishes it requires routine cleaning to remove airborne pollutants, salts and grime that would otherwise degrade the coating over time.

2. Cleaning Frequency

Clean your finish at the minimum frequency below for your environment. More frequent cleaning is beneficial in exposed or polluted locations.

Environment	Minimum cleaning frequency
Standard / inland (sheltered)	Every 3 months
Urban / industrial	Every 1–2 months
Marine / coastal	Every 1–2 months, plus rinse salt deposits between cleans
Pool surrounds	Every 1–2 months (chlorine/salt exposure)

3. The 3-Step Cleaning Procedure

Follow this simple procedure (per Dulux guidelines and AAMA 610.1):

Step 1 — Remove loose deposits. Gently remove dust, dirt and loose debris from the surface with a soft brush or a rinse of clean water.
Step 2 — Wash. Wash the surface using a soft cloth, sponge or soft natural-bristle brush with warm water and a mild pH-neutral (neutral) liquid detergent. Work gently; do not scrub aggressively.
Step 3 — Rinse. Rinse thoroughly with clean fresh water to remove all detergent residue. Allow to air dry.

4. Approved & Prohibited Agents

Cleaning agents & tools
Approved	Warm water; mild pH-neutral liquid detergent; soft cloth, sponge or soft-bristle brush.
Prohibited	Turpentine, white spirits, thinners, petrol, kerosene; abrasive cleaners, scouring pads or powders; strong solvents, acids or alkalis; high-pressure washers directed at the finish.

Warning. Never use turpentine, white spirits, thinners or abrasive cleaners. These will permanently damage the finish and void finish warranty cover. Avoid contact with wet cement, sunscreen and harsh chemicals, and remove any such contact immediately with fresh water.

5. Additional Care

Salt spray — in coastal locations, rinse the finish with fresh water regularly between scheduled cleans to remove salt build-up, especially on surfaces not washed by rain.
Drainage (planters) — keep drainage holes and liners clear so water and soil do not sit against the finish. Standing water and soil contact can stain or corrode over time.
Masking tape & adhesives — avoid leaving tape or adhesive residue on the finish, particularly in sunlight.
Inspect — check the finish during each clean and address any staining or contamination promptly.

6. Maintenance & Your Warranty

Finish warranty cover under our Warranty Policy is conditional on following this maintenance guide. We recommend keeping a simple record of cleaning dates, particularly on commercial projects, so maintenance can be demonstrated if a warranty question arises.
