How to clean and maintain a bronze plaque
Our cast bronze plaques are crafted to stand the test of time, but exposure to the elements can gradually cause oxidation, dirt buildup, and discolouration. With proper care and maintenance, you can ensure your plaque remains beautiful, legible, and well-preserved for years to come.
Why does bronze change over time?
Bronze naturally develops a patina, a thin layer that forms due to oxidation. While some people appreciate the aged, antique look, others prefer to maintain the original polished appearance. Regular cleaning prevents excessive oxidation and helps retain the plaque’s clarity and brilliance.
How to clean a bronze plaque
For routine maintenance, follow these simple steps:
What you’ll need
- Soft cloths or sponges
- Mild soap (such as washing up liquid)
- Warm water
- Soft-bristled brush (for textured areas)
Step-by-step cleaning process:
Remove surface dirt – Wipe the plaque with a dry, soft cloth to remove dust and debris.
Wash with soapy water – Mix mild soap with warm water and gently scrub the surface using a sponge or soft brush. Avoid harsh chemicals or abrasive scrubbers that could damage the finish.
Rinse thoroughly – Use clean water to rinse off any soap residue.
Dry completely – Pat the plaque dry with a soft cloth to prevent water spots or streaks.
Dealing with oxidation and heavy tarnish
If your plaque has developed a green or brown patina that you’d like to remove, use a bronze cleaner or a mixture of baking soda and lemon juice to gently restore its shine. Apply with a soft cloth, let it sit for a few minutes, then rinse and buff dry.
Important note: If your plaque has an intentionally patinated finish, avoid aggressive cleaning methods as they may strip away the desired effect.
How often should you clean your plaque?
Outdoor plaques: Every 3–6 months, depending on exposure to weather and pollution.
Indoor plaques: Once a year is usually sufficient.
Memorial or historic plaques: Regular light cleaning ensures readability while preserving the integrity of the finish.
Final thoughts
With regular care, your bronze plaque will maintain its elegance, readability, and durability for years to come. Whether it’s a memorial, historical marker, or business sign, proper maintenance will ensure it remains a worthy tribute for future generations.
