How to Remove Algae From Wrought-Iron Furniture

Kaye Wagner

Algae can grow on your wrought-iron furniture, especially humid climates where algae grows more frequently and abundantly. Algae growth will discourage people from sitting on your furniture, and can eventually weaken and decay the furniture. Prevent this by cleaning off the algae as soon as you notice it. Letting it grow will make it harder to control.

  1. Attach a high-powered nozzle to your garden hose.

  2. Turn the hose on, and point it at the algae on the wrought-iron furniture. The high-powered water will blast away most of the algae.

  3. Mix 1 gallon of water with 1 tbsp. garden detergent.

  4. Dip a soft-bristled brush into the mixture, and brush over the surface of the wrought-iron furniture to remove the rest of the algae.

  5. Rinse the furniture with clear water.

  6. Let the furniture dry completely.
