Advice

  • If the rust is caused by the metal armor leaking out of the concrete, after removing the rust stains, seal the exposed armor surface with concrete insulation to prevent future rust formation. You can purchase a suitable sealant at any hardware store or DIY store. For use, follow the instructions on the package.
  • For best results use a pressure washer for the rinsing phase.
  • To reduce rust stains, avoid spraying water on concrete surfaces while watering your garden.
