Sculpture Care

Bronze, stainless steel, aluminium, marble, fibreglass, and resin sculptures are all susceptible to damage from environmental and physical sources. Corrosion and staining can result from exposure to pollutants like acid rain, saltwater, and airborne contaminants, while physical harm from vandalism, accidental impact, or lack of maintenance can cause further deterioration.

Bronze Sculptures

When cleaning a bronze statue, it's crucial to avoid abrasive cleaners or tools that could scratch the surface. Opt for a soft cloth and a mild detergent instead. For proper storage, wrap the bronze statue in a soft cloth and keep it in a cool, dry location. Consistent maintenance will help preserve the statue's condition for many years.

  • Dust the sculpture: Use a soft, dry cloth or a soft-bristled brush to gently remove any loose dust or debris from the bronze surface. Take care to avoid scratching or damaging the sculpture.

  • Prepare a cleaning solution: Combine warm water with a mild soap (such as dish soap or gentle hand soap) in a bucket or bowl. Alternatively, you can use a specialized bronze cleaner, following the manufacturer’s instructions closely.

  • Apply the solution: Dampen a soft cloth or sponge with the cleaning solution and gently clean the bronze surface in small sections. Avoid using abrasive materials like steel wool, which can scratch the bronze.

  • Rinse the sculpture: After cleaning the entire sculpture, use a clean cloth or sponge soaked in fresh water to remove any soap residue. Ensure that all soap is rinsed off, as leftover residue can cause discoloration or damage.

  • Dry the sculpture: Gently pat the bronze dry with a soft, dry cloth, taking care not to rub or scratch the surface. Let the sculpture air dry completely before placing it back on display.

  • Apply a protective coating: To protect the sculpture from future damage, apply a thin layer of wax or oil suitable for bronze. Make sure to use a product designed for bronze sculptures and follow the instructions provided by the manufacturer.

Corten Steel Sculptures

Corten steel sculptures are celebrated for their durability in outdoor settings and their long-term resistance to corrosion. However, proper maintenance is essential to maximize their lifespan. In this guide, we'll cover key maintenance tips to help you prolong the life of your weathering steel sculpture. 

  • Regular Cleaning: Maintaining Corten steel begins with regular cleaning. Use a mild detergent or soapy water along with a soft brush to gently scrub the surface, removing dirt, debris, or pollutants. Rinse thoroughly with clean water and allow it to air dry.

  • Prevent Debris Buildup: Keep leaves, branches, and other debris from gathering on Corten steel surfaces. Such buildup can trap moisture and interfere with the natural weathering process.

  • Avoid Standing Water: Standing water can speed up corrosion and negatively impact the development of the desired patina. Ensure proper drainage to prevent water from pooling on or near the steel.

  • Use Gentle Cleaning Methods: Refrain from using harsh chemicals, abrasive cleaners, or power washers on Corten steel, as these can damage its protective patina and accelerate rusting. Be mindful of placement, as runoff from salted walkways can compromise the integrity of the steel.

  • Routine Inspections: Regularly inspect your Corten steel for any signs of damage or excessive corrosion. Addressing issues early helps prevent further deterioration and extends the life of your installation.

Marble Sculptures

Maintaining the beauty of your marble or granite sculpture is simple with some regular care. Here’s a step-by-step guide to keeping it in top condition:

  • Clean regularly: Use a soft cloth or sponge with a gentle, non-abrasive soap to clean your sculpture's surface frequently. This helps prevent dirt and debris buildup that can cause damage over time. Rinse thoroughly with clean water and dry with a soft cloth.

  • Avoid harsh chemicals: Steer clear of using abrasive cleaners or strong chemicals on your sculpture, as these can cause surface damage and discoloration.

  • Protect from the elements: If your sculpture is outdoors, consider placing it under a covered area or using a protective cover to shield it from rain, snow, and direct sunlight.

  • Inspect for damage: Regularly check your sculpture for signs of wear, such as cracks, chips, or discoloration. If you find any issues, consult a professional art conservator for guidance on repairs.

  • Apply a sealer: To protect the surface from moisture and damage, apply a sealant every few years. This will help prevent water and other liquids from penetrating the surface.

  • Wax the surface: Applying a thin layer of wax designed specifically for marble or granite can help guard against scratches. Follow the manufacturer’s instructions for best results.

Stainless Steel Sculptures

Stainless steel sculptures are often used to enhance gardens, plazas, and interior spaces. Their polished surfaces blend effortlessly with other art pieces, adding a touch of timeless elegance. Similar to sterling silver, their beauty deepens with time and use. However, stainless steel can be vulnerable to damage, especially from corrosive elements like acid rain. To maintain the lasting shine and elegance of stainless-steel sculptures, consider these essential maintenance tips.

  • Regular cleaning: This is key to maintaining your stainless-steel sculpture's appeal. While daily upkeep isn't necessary, remove any dirt as soon as it appears to keep the sculpture looking its best. This simple approach saves time and money by avoiding the need for more intensive cleaning later.

  • Use a soft cloth: Use lukewarm water or add a bit of glass cleaner for extra shine. Avoid harsh or abrasive products, as they can scratch the surface. After cleaning, dry the sculpture with a microfibre cloth to prevent streaks.

  • Avoid aggressive chemicals: Particularly chlorides, as they can damage the surface. If chlorides come into contact with the sculpture, rinse them off immediately to preserve its shine.

  • Be mindful of scratches: This can lead to corrosion. Even though stainless-steel resists rust, deep scratches can allow moisture to reach the metal, starting a difficult-to-remove corrosion process. Always clean along the grain of the finish to prevent micro-scratches that can dull the surface.

Keep metal objects and other items off the sculpture’s surface to avoid stains. Keeping the sculpture free of clutter will help preserve its pristine appearance over time.
