Stainless steel is resistant to acidic corrosion
Stainless steel is widely known for its corrosion-resistant properties, which make it a popular choice for both consumer and industrial applications. This resistance to corrosion is due to the presence of a thin oxide layer, known as a passive layer, on the steel's surface. The formation of this layer is dependent on the chromium added to the stainless steel—it must contain at least 10.5% chromium for the layer to form effectively. This chromium oxide layer, also known as a passivation layer, forms when the surface of the metal comes into contact with oxygen, rendering the surface electrochemically passive in corrosive environments.
The corrosion resistance of stainless steel was first recognised in the early 19th century when scientists observed the resistance of chromium-iron alloys to oxidising agents. In 1821, Pierre Berthier noted the resistance of these alloys against certain acids and suggested their use in cutlery. Over the next century, various researchers continued to experiment with chromium alloys, leading to the development of what we now know as stainless steel.
While stainless steel is generally resistant to acidic corrosion, the exact resistance levels can vary depending on several factors. These factors include the type of steel, the concentration and type of acid, and the environmental temperature. For example, hydrochloric acid is known to damage stainless steel and should be avoided, while phosphoric acid and nitric acid do not pose a threat to the steel at room temperature. Additionally, the chromium content plays a crucial role in the steel's resistance to different types of acids. Increasing the chromium content, along with molybdenum, provides greater resistance to reducing acids, while increasing chromium and silicon content enhances resistance to oxidising acids.
In the context of cooking with vinegar in a stainless steel pot, it is important to note that vinegar is considered a mild acid. Therefore, it is unlikely to cause significant corrosion to your stainless steel cookware. However, it is always advisable to refer to the manufacturer's instructions for specific care and maintenance guidelines for your stainless steel products.

Vinegar is a mild acid
Vinegar is often used in cooking, food preservation, and cleaning. It is commonly diluted with water, which lessens its acidity and raises its pH level. For example, a mixture of one part vinegar to three parts water can be used to clean stainless-steel pans and remove chalky buildup caused by hard water.
Stainless steel is generally resistant to acidic corrosion, but the exact resistance level depends on the type of steel, concentration and type of acid, and environmental temperature. However, stainless steel is not impervious to discolouration and stains from everyday use. Therefore, it is important to know how to clean stainless-steel pans properly to maintain their finish.
While vinegar is considered a mild acid, it is important to note that at higher concentrations, such as those encountered in laboratories or factories, acetic acid can be a strong irritant to the eyes, skin, and mucous membranes. Prolonged skin contact with concentrated acetic acid can lead to tissue destruction, and inhalation of high concentrations of acetic acid vapours can irritate the eyes, nose, and throat.

Vinegar is effective for cleaning stainless steel
Vinegar is an effective and inexpensive way to clean stainless steel. It is a mild acid that can cut through grease and grime without damaging the steel. Stainless steel is naturally resistant to corrosion, but vinegar can help remove fingerprints, grease, and grime from its surface.
To use vinegar to clean stainless steel, fill a spray bottle with undiluted distilled white vinegar and label it clearly. Spray the vinegar liberally onto the stainless steel surface, starting at the top of the appliance and working across. Use a soft microfiber cloth to wipe away the vinegar, following the grain of the steel. If there are stuck-on food bits, sprinkle some baking soda onto the cloth to act as a gentle abrasive. Rub the baking soda gently onto the surface, again following the grain of the steel.
For tougher messes, such as burnt food or oil, a more abrasive cleaning method may be required. Bring a mixture of one part vinegar to three parts water to a boil in the stainless steel pan. Allow the mixture to cool, then wash the pan with soap and water. For smaller water spots, wipe the pan with a damp sponge sprinkled with baking soda. To prevent water spots, always dry your cookware immediately after washing.
While vinegar is generally safe to use on stainless steel, it is important to take some precautions. Avoid getting vinegar in your eyes, and keep it out of the reach of children, as it can irritate the skin and digestive system. Test vinegar on a small, inconspicuous area of stainless steel before using it on the entire surface, especially if you are concerned about potential damage. Additionally, if you live in an area with hard water, use distilled or bottled water when cleaning, as tap water can leave spots or streaks on stainless steel.

Vinegar can be used to remove factory oils
Cooking with vinegar in a stainless-steel pot is generally considered safe, as stainless steel is resistant to acidic corrosion. However, the resistance level depends on the type of steel, acid concentration, and environmental temperature. Heating diluted vinegar in a stainless-steel pot for a short period, as in the case of making a marinade, is unlikely to cause damage. Nevertheless, it is recommended to follow manufacturer instructions for specific washing and usage tips.
Now, regarding the use of vinegar for removing factory oils, there are mixed opinions. Some sources suggest that vinegar can be effective in removing residual oils from surfaces. For example, a dog training organization recommends using vinegar to remove residual oils that could interfere with scent training for search dogs. In this context, vinegar is believed to neutralize acids and reduce odours, making it easier for dogs to detect target scents.
However, other sources dispute the effectiveness of vinegar for oil removal. One source suggests that vinegar is neither an oil solvent nor a solute, and mixing vinegar with oil will not result in the dissolution of oil. Additionally, vinegar is said to lack detergents, which are necessary for lifting away dirt and dissolving oils. As such, vinegar may not be the best choice for removing factory oils, as it may not effectively break down and remove the oil residues.
It's important to note that while vinegar may not be the most effective oil remover, it can still be useful in certain contexts. For instance, vinegar can help neutralize acids and reduce odours, as mentioned earlier. Additionally, vinegar's acidic nature can be beneficial for dissolving hard water deposits, such as calcium and magnesium, which is why it is sometimes recommended for cleaning bathrooms. Nevertheless, even in bathroom cleaning, vinegar should be used in conjunction with detergents and disinfectants to ensure the removal of all dirt, body oils, and germs.

Bleach can damage stainless steel
While stainless steel is designed to resist corrosion and rust, it is susceptible to discolouration and burnt-on messes. Stainless steel is generally resistant to acidic corrosion, but the exact resistance level depends on the steel used, the concentration and type of acid, and the environmental temperature. For example, vinegar is a mild acid, and while it can be used in stainless steel pots, some sources recommend diluting it first.
Despite being a common disinfectant, bleach should not be used on stainless steel. Bleach will corrode stainless steel over time, creating small openings that allow further corrosion and rusting of the metal. The chloride in bleach attacks the layer of chromium that makes stainless steel resistant to corrosion and rust. While one application may not cause damage, repeated use will cause pitting and rusting.
There are alternative ways to clean stainless steel. For everyday use, a non-abrasive sponge and hot soapy water can be used. For more stubborn stains, a mixture of vinegar and water can be boiled in the pan, and then washed with soap and water. Baking soda can also be used to remove water spots.
It is important to always refer to the manufacturer's instructions for specific washing tips.
