How do you prevent white rust on an aluminum landscape tree box?
White rust, a common issue on aluminum surfaces, can mar the appearance and durability of landscape tree boxes. To prevent this unsightly corrosion, follow these practical steps:
1. Regular Cleaning: Dirt and moisture accelerate corrosion. Clean the aluminum surface with mild soap and water every few months to remove contaminants.
2. Apply Protective Coatings: Use a clear acrylic or polyurethane sealant to create a barrier against moisture and oxidation. Reapply as needed, especially in humid climates.
3. Ensure Proper Drainage: Standing water promotes rust. Drill small drainage holes in the tree box to prevent water accumulation.
4. Avoid Harsh Chemicals: Chlorides and acids can damage aluminum. Use pH-neutral cleaners and avoid de-icing salts nearby.
5. Inspect Frequently: Check for scratches or chips in the coating. Touch up damaged areas promptly to prevent rust from forming.
By implementing these measures, you can maintain the beauty and longevity of your aluminum landscape tree box while keeping white rust at bay.
