Cleaning Powder Coatings

To clean architectural powder coatings effectively while preserving their appearance and durability, follow these steps:

Regular Cleaning Frequency: Clean the powder coated surfaces every 3 to 6 months in standard environments and more frequently (every 1 to 3 months) in harsher environments, such as coastal or industrial areas, to prevent build-up of pollutants and salt deposits.

Gentle Cleaning Solution: Use a mild detergent mixed with warm water (a pH-neutral cleaner or a solution of mild dish soap with water works well). Do not use abrasive cleaners, strong solvents, and chemicals like acetone, turpentine, or bleach, as they can damage the coating.

Soft Cleaning Tools: Use a soft, non-abrasive cloth, sponge, or a soft-bristle brush to avoid scratching the powder coating. Don not use steel wool or harsh scrub pads.

Washing Technique: Gently wash the surface using the soapy water solution. Rinse thoroughly with clean water to remove all detergent residues, which can cause staining if left behind.

Drying: Use a soft microfibre cloth to dry the surface and prevent water spots from forming. Allowing the surface to air dry naturally is also acceptable in less critical applications.

Stubborn Stains: For tougher stains, use a non-abrasive cleaner specifically designed for powder coatings or a diluted vinegar solution, but always test a small area first.

Additional Tips:

Cleaning powder coated glazed frames can be undertaken at the same time as cleaning glazing. This ensures that polution contaminants from window cleaning are not left on the frame or cills of powder coated profiles.

Avoid pressure washing, as high pressure water can damage the coating.

If the coating shows signs of significant damage, consider consulting a professional for refinishing or touch-ups.

Always follow the manufacturer’s recommendations for cleaning and maintenance to avoid voiding warranties.
