Begin by combining a few drops of dish soap with a bucket of water to create a soapy mixture. Dip a clean microfiber cloth in the solution and rub it across the rusted furniture. This won’t just clean the surface and get rid of dirt and debris but also make it easier for you to spot areas that need correction. After you’re done, tear off some aluminum foil from the roll, crumple the foil into a ball, and gently rub it onto the affected areas. You can do this with both sides of the foil.
However, if the rust is incredibly stubborn, dip the crumpled foil ball into a salt and water solution to increase its efficacy. Don’t forget to dip the ball into the solution whenever it dries out to allow it to loosen the rust’s hold on the furniture and reduce the time and effort you’ll have to put in to restore it. Alternatively, you can combine white vinegar and water in a 1:1 ratio and spray this solution over the rusted parts or dip the foil in it before you rub the rust off with the aluminum ball.
Remember, you might have to rub the rusted patches a couple of times to uncover the shiny surface underneath. Once the furniture is free of rust, use a microfiber cloth to dry and shine it. When done, apply a thin coat of paint or varnish to weatherproof your outdoor furniture.
