When you live in a region with a climate that contains a lot of moisture, then the furniture in the yard, on the deck, porch or patio might start to develop algae in its nooks and crannies. If left untreated, algae — along with excessive moisture — can weaken wrought-iron furniture and cause it to rust. While algae appears unsightly, it does not take much effort to eliminate it and maintain your wrought-iron furniture looking new.
Fill a bucket with warm water and add several drops of liquid dish soap. Swirl the mix around with your finger to create suds.
Dip a stiff-bristled brush into the sudsy water. Scrub the algae covered spots on the wrought-iron furniture. This removes the majority of the algae, in addition to dirt and other debris.
Attach a nozzle to the hose to better direct the spray and boost the water pressure in the hose. Spray the algae-cleaned regions with the hose and nozzle. You might also wipe it with a moist cloth. Let dry in the sun.
Employ a powerful disinfectant or sterilizing solution to the algae-stained area. You can create a homemade disinfectant that is safe for outdoor plants and use by mixing a solution of oxygen bleach and water following package instructions.
Allow the disinfectant or sterilizing solution set for 24 hours, then rinse it away.
