Removing rust from stainless steel – here's how to get rid of rust stains!

Hardly any outdoor furnishings can do without weather-resistant stainless steel, from which you should, however, regularly remove rust. Contrary to popular belief, this high-quality metal is still susceptible to corrosion. Thus, the metal is described as corrosion-resistant, but not as immune to corrosion.

So, if you're the proud owner of high-quality stainless steel outdoor equipment like bin enclosures , it's important to know how to remove rust from stainless steel. But don't worry, you've come to the right place. In this article, we'll show you why it's necessary to remove rust from stainless steel and the best way to do it. You'll also find important tips on how to prevent corrosion in the first place.

Why do rust stains appear on stainless steel?

Stainless steel is a popular material for outdoor use. Many furniture makers and architects rely on stainless steel elements, which are weather- and corrosion-resistant, meaning that bin enclosures , benches, and garden furniture made from this material are generally rust-free. But beware! Even stainless steel can rust under certain conditions. As soon as you discover rust-colored spots on the surface of the stainless steel, you need to act quickly!

But how is it possible for rust to form on stainless steel that is supposedly corrosion-resistant and needs to be removed so urgently? The answer lies in the type of rust you're dealing with. The rust spots on stainless steel are surface rust, which you should remove. This is a superficial layer of rust that can occur on lower-quality stainless steel or forms when the stainless steel comes into contact with other objects affected by rust.

Since surface rust is only a superficial layer and stainless steel is generally corrosion-resistant, one might think that these rust spots pose no further problem and are merely unsightly. However, appearances are deceiving. You should remove surface rust from stainless steel immediately, as it can cause lasting damage in the long run. This type of rust also slowly but steadily eats its way into the stainless steel, making its removal absolutely essential.

How to remove rust from stainless steel

Now that you know what stainless steel rust is all about, we'll show you how to remove it. We've made sure to present a balanced mix of different methods, including both tried-and-tested home remedies and powerful specialty cleaners to help you tackle those stubborn brown stains.

Proven home remedies to remove rust from stainless steel

The great thing about home remedies is that you're likely to already have them on hand. Fortunately, this also applies to our selection of home remedies for removing rust from stainless steel. So, if you notice corrosion on your exterior fittings, search your cupboards for the following items:

• Vinegar and baking soda: The combination of vinegar and baking soda is a tried-and-tested remedy for removing discoloration and rust from stainless steel. First, wipe the affected area with a cloth soaked in vinegar. Then, sprinkle baking soda onto the corroded area and rub it in using a soft cloth or sponge. After removing the rust from the stainless steel, rinse the treated area with clean water and dry it thoroughly with a cloth.

• Salt and lemon juice: If you don't have the two ingredients mentioned above at home, you can use salt and lemon juice as an alternative. With this treatment, you should also first moisten the affected area. It's best to use freshly squeezed lemon juice for this. Then take the salt and sprinkle it onto the area.

Thanks to the lemon juice, the salt adheres, allowing you to let it sit for 5 to 10 minutes. After this time, you'll need to do some manual work. Use a soft sponge or toothbrush to remove the rust from the stainless steel. Finally, rinse the treated areas with clean water and dry them thoroughly.

Special cleaners for tough cases

If you're trying to remove surface rust from stainless steel but your efforts are unsuccessful, this indicates that the rust layer has already partially penetrated the material. Now it's time for decisive action. This means you should use specialized cleaners specifically designed for removing rust from stainless steel.

Specifically, you should look for cleaning products labeled "stainless steel cleaner" or "rust remover." It's important to avoid products containing harsh chemicals, as these can damage the material itself. Once you've found a suitable cleaning product, you can follow the instructions below, which will guide you step-by-step on how to properly remove rust stains from stainless steel:

1. Apply cleaning agent: First, apply the product to the affected areas. Follow the manufacturer's instructions regarding quantity and contact time.

2. Removing rust from stainless steel: After the soaking time, you should take a soft cloth or sponge and remove the rust from the stainless steel.

3. Dry the affected areas: Finally, dry the treated areas with a cloth and polish them.

Prevent rust from forming on stainless steel

Just as important as the immediate removal of surface rust from stainless steel are preventative measures, which we also want to share with you. This is crucial so you can avoid having to regularly remove rust from stainless steel. However, proper prevention and care of the metal is not only essential to saving you unnecessary work.

It also protects your exterior from corrosion in the long term. It's quite possible that you might overlook rust on stainless steel and therefore not remove it. As explained above, this can lead to lasting damage. To avoid such unpleasant surprises, you'll find the most important tips for preventative care below.

Preventive measures against rust on stainless steel

The origin of surface rust, which can affect stainless steel, lies in iron dust that corrodes in the air and settles on stainless steel surfaces. Other rusting metal objects nearby can be problem areas. Since iron dust can be carried over long distances, it can be difficult or impossible to keep all other metal objects away from your stainless steel equipment.

Therefore, it is essential to regularly wipe down your exterior fittings with a mild detergent. This removes any iron dust and other dirt before rust stains can form on the stainless steel. This way, you're on the safe side! It's important to wipe the surfaces thoroughly dry, as moisture also promotes corrosion. Avoiding scratches on the surfaces is also crucial. These damage the protective outer layer of the material and serve as entry points for rust, which then has to be painstakingly removed from the stainless steel.

Opt for exterior fittings made of treated stainless steel.

Powder coating and hot-dip galvanizing are perfect complements to stainless steel exterior equipment. This combination can be seen, for example, on our bin enclosures . It gives the enclosures an additional protective layer against weathering and corrosion. This means that the stainless steel of these enclosures is also protected against surface rust. Nevertheless, we recommend cleaning such exterior equipment regularly. Scratches in the powder coating should also be repaired promptly to prevent weak points.

Conclusion: Remove rust from stainless steel with simple tricks

Removing rust from stainless steel is important because even this resilient material will eventually succumb to corrosion. After reading our article, you'll be well-equipped to combat corrosion. While superficial rust stains on stainless steel can often be removed with simple household remedies, you should use rust removers or stainless steel cleaners for more stubborn cases. However, even before corrosion becomes apparent, you can take preventative measures by regularly cleaning your outdoor equipment and, for example, opting for bin enclosures that are hot-dip galvanized and powder-coated.
