Maintaining your Aço corten products is simple, as they are designed to develop a protective rust layer that enhances durability. However, proper care can help ensure longevity and appearance. Here are some key maintenance tips:

1. Allow Proper Weathering

• Corten steel develops its signature rust patina over 6–12 months, depending on the environment.
• Ensure proper drainage to avoid water pooling, which may cause excessive rusting.

2. Cleaning & Surface Care

• Remove debris (leaves, dirt) regularly to prevent moisture retention.
• If needed, clean with mild soap and water—avoid harsh chemicals that may strip the patina.
• For stubborn stains, use a soft brush or cloth; do not use aggressive scrubbing tools.

3. Preventing Staining on Surroundings

• During the early rusting phase, Corten steel may bleed, leaving stains on nearby surfaces.
• To reduce this, place a drainage tray or protective barrier under the product.
• Sealing surrounding surfaces (like concrete or wood) with a water-resistant coating can prevent staining.

4. Enhancing & Controlling Patina Development

• If you want a faster rusting effect, spray with a vinegar-salt-water solution to accelerate patina formation.
• To slow rusting, you can apply a rust stabilizer or clear sealer, but this may alter the natural weathered look.

5. Winter & Moisture Considerations

• In humid or coastal areas, extra care is needed to avoid excessive corrosion.
• For Corten steel fire pits or BBQ grills, remove ash and moisture after use to prevent accelerated rusting.

6. Long-Term Maintenance

• Check periodically for structural integrity, especially for thin sheets or welded joints.
• If any rusted sections weaken over time, light sanding and re-oxidation (exposing bare metal to moisture and air) can help restore the patina.

By following these simple maintenance steps, your Corten steel fire pits, water features, planter boxes, and decorative panels will remain durable and aesthetically appealing for years to come!
