How to Remove Rust Stains

Rust stains are usually a result from problems with the water supply. For instance, if you live on a well and use hard water, you’re more likely to get rust stains since the water supply has a higher iron percentage. If this is a common occurrence, then it’s a sign that there is a problem with the water or with the plumbing, and you should get a plumber in to take a look. As annoying as this is, removing the rust, or at least lightening it, is easily done with common household ingredients.

Citric acid: Citric acid is available in both liquid and crystal form; both are usually available in drug or grocery stores. If you own a stainless steel dishwasher or one with stainless steel components, you should opt for the liquid form as the crystals can scratch the surface of the steel. If you don’t want to spend extra on citric acid, you can also use table salt and lemon juice to remove rust. To remove the rust stains, first, fill the detergent holder with four ounces of citric acid and turn the dishwasher on for a full cycle. When it’s done, run another cycle with a cup of detergent. You can repeat the process if the rust is not completely removed. You can also manually scrub the rust off with the citric acid if there is only a small amount.

White vinegar: Using white vinegar to remove rust stains is easy, as it helps dissolve the rust off of metal surfaces, but it takes time. To use white vinegar, pour it over the rusted areas and allow it to sit for a couple of hours. After, use a damp cloth to wipe away the rust. You can also run a cycle with the vinegar as well.

Potatoes and salt: Potatoes contain oxalic acid, which like citric acid and vinegar, help dissolve the rust off of metal surfaces. The salt is used as an abrasive to remove the rust. To use this method, cut a potato in half and spread enough salt over the cut surface to cover the whole potato. Then, simply take the potato and firmly scrub it over the rusted areas, adding more salt as needed. Once the rust is completely gone, wipe down the surface of the dishwasher with a damp cloth.

Baking soda: You can also use baking soda in place of citric acid to remove rust stains. Take some baking soda and add water to make a paste. Then, spread it over the rusted areas of your dishwasher; you can add more water if it gets too dry, which can scratch the surface. Then, with a sponge, scrub the rust off. This works well on metal surfaces.

To stop the rust from recurring, get your plumbing checked to find out where the rust was coming from. Also, keep objects that are more likely to rust out of your dishwasher, which is consists mainly dishes made from steel. If you need to place stainless steel dishes in your dishwasher, thoroughly rinse them first, especially if you’re not turning the dishwasher on for awhile. These methods also work on washing machines, garden tools, metal dishes, car rims, and any other metal surface.
