Maintaining Powder-Coated Planters

Powder-coated aluminum needs little care, but the care it needs matters: rinse off what sits on the surface, keep water moving, and deal with chips early. The right cleaner and interval depend on the coating and the site; the steps below are safe for most powder coatings.

Routine inspection

Look for soil and leaf buildup, standing water, blocked drains, irrigation overspray, salt and fertilizer residue, scratches, chips, chalking, fading and loose fasteners. Pay most attention to rims, seams, welds, edges, feet, drain openings and anywhere tools, carts or furniture touch the finish.

Cleaning, step by step

1. Rinse off loose dirt, leaves and soil with a garden hose.
2. Wash with a soft cloth or sponge and a mild detergent in lukewarm water, such as a few drops of dish soap.
3. Test anything stronger on a hidden spot first.
4. Rinse thoroughly so soap and loosened salts do not stay in seams or around drains.
5. Let the surface dry, or wipe it dry to avoid water spots.

Avoid abrasive pads, scouring powders, solvents such as acetone or lacquer thinner, bleach, and strong acid or alkaline cleaners. A pressure washer held close can lift the coating at edges and drive water into joints; if you use one, keep it on a wide fan and well back.

How often

Powder manufacturers commonly suggest cleaning at least once a year, and every few months near salt water, salted roads, busy streets or industrial air, or where irrigation spray, fertilizer or bird droppings land on the finish. Clean sooner whenever something acidic or sticky, such as sap or droppings, sits on the surface.

Chips and scratches

Photograph damage when you find it. On aluminum, a chip exposes metal that will not rust red but can corrode under the edge of the coating if salt and water get in, so touch it up promptly: clean and dry the spot, feather the edge lightly, and apply a touch-up paint matched to the finish colour on your order. A field touch-up protects the metal but will not exactly match the gloss and texture of the factory finish.

Fading and chalking

A dull, powdery surface or a shift in colour can come from sun, heat, chemicals, abrasion or harsh cleaning. Clean a small area with mild detergent first; if the change remains, photograph it and send it to us with your order number rather than trying stronger products.

Planter-specific care

• Keep drains and overflow paths open.
• Keep wet soil, mulch and fertilizer from sitting against the outside of the planter.
• Aim irrigation so water and dissolved salts do not run down the same face every day.
• Protect the finish where carts, tools or furniture can strike it.
• Do not drill, weld, grind or modify the planter without checking the effect on drainage and the warranty.
• Keep other metals out of direct contact with the planter; where they must touch, use isolating pads or washers.

What the finish warranty covers

Our planters carry a 10-year limited structural warranty and a 2-year finish warranty. Finish coverage depends on the powder-coat tier (Standard Outdoor Finish or Certified Architectural Finish); the tier that applies is stated on your quote or order.

The warranty expects the owner to follow the cleaning and drainage guidance supplied with the order, use mild cleaners and non-abrasive tools, and deal with coating damage promptly. Damage from harsh cleaning, impact, blocked drainage and standing water is not covered. The full terms and the claim steps are on the warranty page.

Keep records

Keep the quote or order, any finish documents, cleaning products used, inspection dates, photos of damage and repairs. They make troubleshooting faster and support a warranty claim.

If the finish on your order is damaged or you are unsure how to clean it, contact us with the order number and photos.
