Powder coating is a popular finish for metal surfaces because it is strong, smooth and durable. It is commonly used on aluminium and steel in window frames, railings, gates, balconies, garden furniture, façade panels, wheels, industrial equipment and architectural metalwork. A good powder coated surface can look smart for years, but it still needs the right care.
Although powder coating is tougher than many painted finishes, it is not maintenance free. Outdoor surfaces are exposed to rain, UV radiation, pollution, bird droppings, road salt, moisture and airborne dirt. Over time, these contaminants can make the coating look dull, chalky, faded or stained. If the surface is cleaned with the wrong products, the protective finish can be damaged and become harder to maintain.

What is powder coating?
Powder coating is a dry finishing process used on metal surfaces. A fine powder is applied electrostatically and then cured in an oven. The result is a hard, even and durable finish that bonds to the surface.
Powder coating is used because it offers:
-
Strong resistance to everyday wear
-
A smooth and even appearance
-
Good colour consistency
-
Better durability than many conventional paints
-
Protection for metal against corrosion and weathering
-
A wide choice of colours and finishes
- Suitability for indoor and outdoor applications
You will find powder coating on many everyday surfaces, including aluminium window frames, steel gates, railings, balconies, outdoor furniture, bicycle frames, wheels, shopfronts and industrial parts.
However, even a strong powder coated finish can deteriorate if neglected or cleaned incorrectly. Want to learn more? Read our in-depth guide about cleaning and protecting plastic.
Why powder coated surfaces need cleaning
Powder coated surfaces are exposed to different types of contamination depending on where they are used. Outdoor metalwork is particularly vulnerable to dirt, traffic film, rainwater, salt, algae, bird droppings and UV radiation.
If dirt remains on the coating for too long, it can gradually reduce the appearance and performance of the surface.
Regular cleaning helps prevent:
-
Dull or chalky appearance
-
Staining from pollution and organic dirt
-
Colour fading
-
Surface roughness
-
Salt damage in coastal areas
-
Corrosion risk if the coating becomes damaged
-
Difficult cleaning later
- Premature ageing of the finish
Cleaning is especially important in coastal, industrial and urban areas, where salt and air pollution can settle on the coating more quickly.

What is the most common problem with powder coating?
The most common problem with powder coating is surface degradation caused by exposure and incorrect maintenance. This usually appears as dullness, chalking, fading or staining.
Common powder coating problems include:
-
Loss of gloss
-
Dull or chalky surface
-
Fading from UV exposure
-
Staining from pollution
-
Salt damage near the coast

Corrosion if the coating is damaged
- Ageing caused by lack of maintenance
Regular cleaning with NC Nano Plastic Cleaner and protection with NC Nano Coating for Plastic helps reduce these issues and makes the surface easier to maintain.
Clean powder coated metal
To clean powder coated metal, you need to treat the finish carefully. The metal underneath may be steel or aluminium, but the visible surface is the powder coating. Cleaning should focus on preserving that coating.
Use this method:
-
Remove grit and loose dirt first
-
Use NC Nano Plastic Cleaner rather than abrasive products
-
Wipe gently with a soft cloth
-
Do not use steel wool or wire brushes
-
Rinse or wipe clean
-
Dry the surface
- Protect with NC Nano Coating for Plastic if needed
This helps maintain both the appearance and protective function of the finish.
Clean powder coated steel
Powder coated steel is often used for gates, railings, industrial metalwork, furniture frames and balconies. The coating protects the steel beneath, so damage to the coating can increase corrosion risk.
When you clean powder coated steel, avoid anything that could scratch or weaken the finish.
Recommended care:
-
Clean regularly, especially outdoors
-
Remove salt and pollution deposits
-
Use NC Nano Plastic Cleaner
-
Inspect for chips or exposed metal
-
Repair damaged coating promptly
- Apply NC Nano Coating for Plastic for additional protection after cleaning
This helps reduce corrosion risk and keeps coated steel looking smarter for longer.
Clean powder coated aluminium
Powder coated aluminium is common in window frames, façade panels, doors, balustrades and architectural systems. Aluminium itself is corrosion resistant, but the powder coating can still become dull or stained.
To clean powder coated aluminium:
-
Use a mild cleaner suitable for coated surfaces
-
Avoid abrasive pads
-
Avoid harsh alkaline or acidic cleaners
-
Rinse or wipe thoroughly
-
Dry the surface after cleaning
- Apply NC Nano Coating for Plastic for longer lasting cleanliness
This helps preserve colour and finish, especially on exterior frames and panels exposed to sunlight and pollution.
Clean powder coated wheels
Powder coated wheels are exposed to brake dust, road salt, tar, mud and cleaning chemicals. Brake dust can be particularly stubborn and should not be left on the surface for long periods.
To clean powder coated wheels safely:
-
Rinse loose grit first
-
Apply NC Nano Plastic Cleaner if suitable for the wheel finish
-
Use a soft wheel brush or microfibre cloth
-
Avoid acidic wheel cleaners unless approved
-
Avoid harsh fallout removers unless suitable for the coating
-
Rinse thoroughly
-
Dry the wheels
- Protect with NC Nano Coating for Plastic to reduce future dirt adhesion
Always test first, especially on custom or delicate finishes.
How to restore dull powder coating
Dull powder coating is often caused by UV exposure, oxidation and surface contamination. If the coating is not structurally damaged, it may be improved through cleaning and protection.
A restoration routine can include:
-
Clean thoroughly with NC Nano Plastic Cleaner
-
Remove dirt, traffic film and oxidation
-
Allow the surface to dry completely
-
Apply NC Nano Coating for Plastic evenly
-
Let the coating cure
- Maintain with mild cleaning
This can help improve appearance, reduce dullness and protect the surface from further weathering. If the coating is cracked, peeling or badly damaged, repainting or recoating may be required.
Powder coating cleaner versus household detergent
A mild household detergent may be acceptable for light cleaning, but it may not be enough for pollution, oxidation or outdoor grime. Some household cleaners can also be too harsh or leave residues.
NC Nano Plastic Cleaner is more suitable when you need a dedicated cleaner for coated and plastic like surfaces. It is designed to clean without the aggressive effect of strong solvents or abrasive products.
Use it when the surface has:
-
Traffic film
-
Outdoor dirt
-
Grease marks
-
Early oxidation
-
Dullness
-
Pollution deposits
- Stubborn grime
Why protect powder coating after cleaning?
Cleaning removes dirt, but it does not stop new dirt from settling. After cleaning, applying NC Nano Coating for Plastic helps protect the surface and reduce future build up.
Benefits of protection include:
-
Reduced dirt adhesion
-
Water repellent surface
-
Easier future cleaning
-
Better resistance to UV related ageing
-
Less staining from pollution
-
Longer lasting appearance
- Reduced maintenance effort
This is especially useful for surfaces exposed to sun, rain, road dirt or coastal air.
What should you avoid on powder coating?
To protect the finish, avoid products and methods that can scratch, soften or chemically attack the coating.
Avoid:
-
Steel wool
-
Wire brushes
-
Scouring powder
-
Abrasive pads
-
Strong acids
-
Strong alkaline cleaners
-
Paint thinner
