The following is not a method we have tried and tested, but apparently oxalic acid in a potato also dissolves the oxide. To prevent rust from forming on metal cookware, do not allow metal to dry in the air. Just after washing, dry the metal container with a microfibre cloth to remove water from the pans or cutlery. Avoid stainless steel rusting by seasoning the pan before first use and seasoning it continuously and routinely as it is used. You can also buy chrome-plated stainless steel kitchen utensils that help protect the metal from rust. By completely cleaning stainless steel pans after use, the metal looks great and lasts longer.
Soap helps eliminate dirt overall, while oxalic acid in potatoes helps break rust. Once the oxide has disappeared, rinse and dry the item well. If you have rust in an area that is difficult to reach, a baking soda paste is probably the best option!
Rub salt over the rusty area you want to clean. Once coated, cut a lemon in half and squeeze the juice over the salt. Let the salt and lemon juice mixture remain in the item for two hours. For sturdy stains, use steel wool or a wash cushion. If you don’t want to scratch the metal, use a soft brush or cloth. You will have to scrub much more with a softer tool.
Lime and salt are another solution to remove rust from metal elements. Just sprinkle a little salt over the area of the rusty object and make sure it is completely covered. Then squeeze the lime or lemon everywhere.
You can use white vinegar to effectively remove rust. The oxide reacts with the vinegar and then dissolves. Soak the rusty metal object in white vinegar for a few hours and then just clean to remove the rust. If the object is too large, rust remover simply pour white vinegar evenly over the surface of the object and give it some time to settle. Alternatively, you can also use a white vinegar soaked cloth to clean the object. Try to use white vinegar for a more stubborn oxide.
Vinegar is one of the best natural cleaning agents. To remove rust from small items such as knives and hand tools, soak them in a bowl of vinegar. Remove the item and rub with a metal brush or steel wool. Rinse with clean water and dry with a towel.
When the metal is rusted, it is not always an option to throw it away and buy a replacement. Any method of removing rust requires a little patience and a little grease to remove the rust. But with some time and effort, you can remove rust from many metal surfaces. It turns out that the oxalic acid in potatoes is also delicious to remove rusty items. As the potato surface gets more rust, cut a thin slice and repeat the process until the oxide disappears.
Finish by rinsing and drying the piece completely. Note that objects may appear black after soaking in vinegar or lemon juice, but they should return to their original color after rinsing with water. It is also a good idea to keep ingredients, such as vinegar, borax and baking soda, away from children and pets.
