can you use bleach on stainless steel

Do you have stainless steel kitchen appliances? If so, do you know about the dangers of bleach?

Bleach is a type of household disinfectant that comes in both liquid and powdered form. It is used to clean almost everything, including stainless steel appliances. Surprisingly, bleach can also damage stainless steel.

If you use bleach on your stainless steel appliance, it may not work as planned. The disinfectant works by breaking down the bonds between molecules in the alloy. This results in weakening the material and decreased durability.

can you use bleach on stainless steel

Yes, you can use a diluted solution of bleach on stainless steel, but it is not recommended. Bleach can be harsh and abrasive, and it can damage the protective layer on stainless steel, making it more susceptible to corrosion and discoloration. It is best to use a mild, non-abrasive cleaner on stainless steel to avoid damaging it.

What is stainless steel?

Stainless steel is a type of steel that contains at least 10.5% chromium. Chromium is a naturally-occurring element that is found in rocks, animals, and plants. When it is added to steel, it forms a thin layer of chromium oxide on the surface of the steel, which acts as a barrier to prevent oxygen and water from reaching the steel underneath. This makes stainless steel resistant to corrosion and staining, and gives it its distinctive shiny appearance. Stainless steel is used in a wide variety of applications, including cookware, cutlery, surgical instruments, and many other items that are exposed to moisture or corrosive elements.

What is bleach?

Bleach is a chemical that is used as a disinfectant and a whitening agent. It is typically made from a mixture of water, sodium hypochlorite, and other chemicals. When used as a disinfectant, bleach is added to water to create a solution that can be used to kill bacteria and other microorganisms. It is commonly used in households to clean and disinfect surfaces, and it is also used in the healthcare industry to sterilize equipment. When used as a whitening agent, bleach is added to laundry detergent or applied directly to fabrics to remove stains and make them appear brighter and whiter. It is important to handle and use bleach carefully, as it can be corrosive and can cause skin and eye irritation.

Why You Should Avoid Using Bleach on Stainless Steel

While bleach is a powerful disinfectant and cleaning agent, it is not suitable for use on stainless steel surfaces. Bleach and other cleaners containing chlorine can cause staining and damage to stainless steel. The acidic content of bleach can strip away the protective chromium oxide layer, leaving the stainless steel vulnerable to corrosion and pitting over time. Therefore, it is essential to avoid using bleach as a cleaning solution for stainless steel.

The Damaging Effects of Bleach on Stainless Steel

When bleach comes into contact with stainless steel, it can cause several undesirable effects. The acidic nature of bleach can react with the metal surface, leading to the formation of bleach stain spots. These spots appear as discoloration or patches on the stainless steel, marring its appearance. Additionally, prolonged exposure to bleach can weaken the protective layer of chromium oxide, making the stainless steel more susceptible to rust and corrosion.

Safe and Effective Cleaning Methods for Stainless Steel

To maintain the cleanliness and shine of your stainless steel appliances and surfaces without risking damage, it is recommended to use safe and effective cleaning methods. Here are some alternatives to bleach that you can consider:

Commercial Cleaners for Stainless Steel

There are numerous commercial cleaners specifically designed for stainless steel. These cleaners are formulated to remove dirt, fingerprints, and grease while being gentle on the metal surface. When using a commercial cleaner, it is important to read the instructions carefully and follow the recommended application method. It is also advisable to spot-test the cleaner on a small, inconspicuous area before applying it to the entire surface.

DIY Solutions for Cleaning Stainless Steel

If you prefer a more natural approach, you can create your own cleaning solution for stainless steel. One effective DIY method involves using a mixture of mild dish soap and warm water. Simply dilute a small amount of dish soap in warm water, dampen a soft cloth or sponge with the solution, and gently wipe the stainless steel surface. Afterward, rinse the surface with clean water and dry it thoroughly with a soft cloth. Another alternative is to use a tiny amount of oil, such as mineral oil or olive oil, to polish and protect the stainless steel after cleaning.

Spot-Testing and Following Directions

Regardless of the cleaning method you choose, it is crucial to spot-test any new cleaner or solution before applying it to the entire stainless steel surface. This helps ensure that the cleaner does not have any adverse effects or cause discoloration. Additionally, always follow the directions provided by the manufacturer or the DIY recipe, as different stainless steel finishes and grades may require specific cleaning techniques.

Removing Bleach Stains from Stainless Steel

If you accidentally clean your stainless steel with bleach and notice bleach stains, there are steps you can take to remove them. One effective method involves using baking soda and water. Create a thin paste by mixing baking soda with water, and gently rub the paste onto the stained areas using a soft cloth, bristle brush, or sponge. Rinse the surface with water and dry it thoroughly. However, prevention is always better than cure, so it is best to avoid using bleach on stainless steel in the first place to prevent any potential damage or staining.


In conclusion, it is not advisable to use bleach on stainless steel due to its potential to cause damage to the metal surface. The acidic content of bleach can lead to bleach stain spots and corrode the protective layer of chromium oxide. To safely and effectively clean stainless steel, consider using commercial cleaners specifically formulated for stainless steel or opt for DIY solutions such as mild dish soap and warm water. Always spot-test new cleaners, follow the instructions provided, and avoid prolonged exposure to harsh chemicals. By adopting these practices, you can maintain the beauty and longevity of your stainless steel appliances and surfaces.
