Bleach can cause stainless steel to rust
While bleach is a powerful solution for sanitizing surfaces, it is not suitable for use on stainless steel pans. This is primarily because bleach can cause stainless steel to rust and corrode.
Stainless steel is known for its resistance to corrosion and rust, but this quality is compromised when the metal is exposed to harsh cleaners like bleach. Stainless steel derives its "stainless" property from a protective layer of chromium oxide that forms when the chromium in the metal comes into contact with oxygen. When this layer is damaged by abrasions or harsh chemicals, rust or pit marks can form and spread rapidly. Bleach contains ingredients that serve as oxidants, and these oxidants can cause the chromium oxide layer to break down, leaving the stainless steel susceptible to corrosion and rusting.
The use of bleach on stainless steel pans can lead to the formation of rust or pitting. This occurs when the protective chromium oxide layer is compromised, exposing the metal to oxidation and corrosion. As a result, it is recommended to avoid using bleach on stainless steel cookware and opt for alternative cleaning methods.
To effectively clean stainless steel pans, it is advisable to use milder cleaning agents and methods. Hand-washing with hot soapy water and a non-abrasive sponge is generally recommended for everyday cleaning. For tougher messes, there are specific commercial cleaners designed for stainless steel, such as Bar Keepers Friend, which can be used according to the manufacturer's instructions. Baking soda is another effective and inexpensive option for removing burnt residue from stainless steel pans.
While some sources suggest diluting bleach with water for use on stainless steel, it is important to note that this practice is not recommended by experts. The potential for rust and corrosion outweighs any sanitizing benefits. Therefore, it is best to avoid using bleach altogether on stainless steel pans and explore alternative cleaning options that are safer and more suitable for this type of cookware.

Bleach is a sanitizing, not a cleaning agent
Bleach is a powerful solution that is used for sanitizing, not cleaning. While it is a good option for bathrooms and commercial food production, it is not recommended for everyday use in the kitchen. This is because bleach is too corrosive for most kitchen surfaces, including stainless steel.
Stainless steel is a staple in any kitchen because it is durable, heats up quickly and evenly, and retains heat well. It is also non-reactive, meaning that you can cook just about anything in a stainless-steel pan without worrying about damaging the surface. However, stainless steel is not impervious to damage and discoloration. Bleach can compromise the protective layer of chromium oxide that forms when the chromium in stainless steel comes into contact with oxygen. This layer is what makes stainless steel "stainless" and rust-resistant. When this layer is damaged by harsh cleaners like bleach, the stainless quality of the steel is compromised, and rust or pit marks can form and spread rapidly.
Dan Dilworth, a restaurant operations director, states that "bleach is not a cleaning agent; it’s a sanitizing agent. It should never be used for anything except to kill pathogens or clean your clothes." Therefore, it is important to opt for a less harsh method when cleaning stainless steel. One option is to use good old-fashioned soapy water, followed by a polish with a stainless steel cleaner or a tiny bit of oil.
If you are going to use bleach to sanitize surfaces in your home, always follow the right protocols. Bleach should always be diluted with water—a common ratio is ½ cup of bleach per gallon of water. Never mix bleach with anything else, such as ammonia or vinegar, as this can cause dangerous, potentially lethal fumes or even an explosion. Bleach solutions should only be mixed as needed and used within one stint of cleaning rather than stored for later use.

Bleach is too strong for everyday use
Bleach is a powerful cleaning solution, and while it can be used to sanitise surfaces, it is too strong for everyday use on certain materials, like stainless steel.
Stainless steel is a popular material for cookware, including pots and pans, because it is durable, heats up quickly and evenly, retains heat well, and is low maintenance. However, stainless steel is not impervious to damage and can be affected by harsh cleaning agents like bleach.
The protective layer of chromium oxide that gives stainless steel its characteristic quality can be compromised by abrasions or harsh chemicals. When exposed to bleach, stainless steel can become oxidised and corroded, leading to the formation of rust or pit marks. These marks can spread rapidly and permanently damage the surface of your stainless-steel pans, compromising their functionality and appearance.
Therefore, it is recommended to avoid using bleach on stainless-steel pans and instead opt for gentler cleaning methods. Everyday cleaning of stainless-steel pans can be effectively achieved with hot soapy water and a non-abrasive sponge. For tougher messes or burnt-on food, there are alternative cleaning methods, such as using baking soda or commercial cleaners specifically designed for stainless steel. By following the manufacturer's instructions and choosing the appropriate cleaning agents, you can effectively clean your stainless-steel pans while preserving their quality and longevity.
