How to Clean and Maintain Your Metal Plaque
Over time, exposure to the elements can cause even the finest bronze or aluminum plaques to lose their original luster. Regular cleaning will help preserve their beauty and ensure your plaque continues to make a lasting impression for years to come.
General Cleaning Recommendations
We recommend cleaning both outdoor and indoor plaques every few months—more frequently if they are exposed to harsh weather, salt air, or pollutants. Most American Cast Bronze Plaques are coated with a clear acrylic polyurethane finish that protects the surface from oxidation and corrosion.
Step-by-Step Cleaning Instructions
-
Prepare a Gentle Cleaning Solution:
Mix warm water with a small amount of mild, liquid dish soap. Avoid using any harsh chemicals, abrasives, or ammonia-based cleaners. -
Use Soft Materials Only:
With a soft cloth, sponge, or rag, gently wipe the plaque in the same direction as the metal’s grain. This helps maintain the texture and sheen without scratching the finish. -
Rinse and Dry Carefully:
Rinse thoroughly with clean water to remove soap residue, then dry immediately using a soft, dry cloth. Allowing water to air-dry on the plaque can leave mineral spots or streaks.
Avoid These Common Mistakes
-
Do not use steel wool, wire brushes, or abrasive pads.
-
Do not apply automotive waxes, sealants, or clear coats unless recommended by the manufacturer.
-
Do not pressure-wash or use harsh cleaners such as bleach or solvents.
Maintaining Brushed or Painted Finishes
Plaques with painted backgrounds or brushed letters should be cleaned gently to avoid damaging the finish. If the painted areas fade or the coating wears over time, professional refinishing may restore the plaque’s original beauty.
