Stainless steel is a durable cookware material, but it is not immune to staining. Chlorine-based cleaners like Comet should not be used on stainless steel because chlorine is corrosive. Bleach can also cause pitting on stainless steel, so it is not recommended to soak stainless steel pans in bleach or to use bleach continuously when washing them.

What You'll Learn
Chlorine-based Comet can cause pitting on stainless steel
While stainless steel is one of the most hard-wearing and durable cookware materials, it is not entirely resistant to staining and corrosion. Pitting, a form of extremely localised corrosion, can occur on stainless steel. This happens when small holes are randomly created in the metal, causing an erosion of the surface.
Chlorine-based cleaners, such as Comet, are not recommended for cleaning stainless steel pans as chlorine is corrosive to steel. Chlorine can cause pitting on stainless steel by breaking down the protective oxide layer on the surface. This protective layer, formed by chromium reacting with oxygen in the air, usually makes stainless steel resistant to corrosion. However, chlorine can compromise this layer, making the steel susceptible to pitting and rust.
The chloride content, pH value, and temperature influence the occurrence of pitting corrosion. Chlorides, such as salt, can attack the passive layer of chromium oxide, resulting in pockmarks and the removal of the oxide. This is why it is advised to avoid using chlorine-based cleaners like Comet on stainless steel pans.
Instead of using Comet, it is recommended to use acid-based cleaners like Bar Keepers Friend or plain white vinegar to clean stainless steel. A plastic scrubber can also be used to avoid scratching the surface. While it is generally safe to wash stainless steel pans with soap and water, it is important to avoid abrasive cleaners and steel wool, as they can also damage the protective layer and make the pan prone to corrosion and rust.

Bleach in Comet can cause corrosion and rust
Another user on Reddit reported using Comet to clean the rust off their pan and asked if it was still safe to use. The responses indicated that while the corrosion would likely get worse, it was still safe to use for cooking. However, one response suggested that the pan in question was actually the lid of a wok, and the cooking part of the wok is typically made of heavy-duty steel.
It is important to note that while Comet with Bleach may not immediately damage stainless steel pans, it is not recommended for long-term use as it can cause corrosion and pitting. Therefore, it is advisable to use alternative cleaning methods, such as soap and water, to avoid potential damage to your cookware.

Thorough rinsing should remove any toxic residue
While stainless steel is one of the most durable cookware materials, it is not immune to staining. The white haze that can appear on stainless steel pans is caused by calcium carbonate, which is present in small amounts in tap water. This substance does not dissolve easily in water or oil, which is why it can remain stuck to your pan even after washing or cooking with oil. While these white deposits are not harmful, they can be unsightly.
To remove these stains, you can use an acid-based cleaner, such as Bar Keepers Friend, or a mixture of vinegar and water. Bring this mixture to a boil in your pan for a few minutes, then discard the liquid and wash and wipe your pan as usual.
If you choose to use Comet to clean your stainless steel pans, thorough rinsing should remove any toxic residue. While Comet is a chlorine-based cleaner, which can be corrosive to stainless steel, a thorough rinse should ensure that no harmful chemicals remain on your pan. Bleach can cause pitting on stainless steel, so it is not recommended to soak your pans or continue to wash them using Comet or other chlorine-based products.
Pitting is an erosion of the surface of the metal caused by chlorides, such as salt. Stainless steel is usually resistant to corrosion due to its chromium content, which reacts with oxygen in the air to form a thin layer of chromium oxide. However, abrasive cleaners or steel wool can strip this protective layer, making your pan susceptible to corrosion and rust. Therefore, it is important to avoid using abrasive cleaners or steel wool on your stainless steel pans, and to always rinse thoroughly after using any cleaning products.

Vinegar and water can remove calcium carbonate deposits
While it is possible to use Comet with Bleach to wash stainless steel pans, it is not recommended to do so regularly as bleach can cause pitting on stainless steel. Instead, it is advised to wash them with soap and water.
Now, if you are looking to remove calcium carbonate deposits from your stainless steel pans, vinegar and water are a great option. Vinegar is an effective and inexpensive way to remove calcium deposits and hard water buildup. It is also non-toxic, so you don't have to worry about any harmful chemicals.
To remove calcium deposits, combine equal parts vinegar and water in a spray bottle. Then, using a scrub brush, spot-treat and scrub the affected areas with the vinegar-water mixture. The acidity in the vinegar will help break down the mineral crystals, removing the calcium deposits. After cleaning, let the surface dry for 48-72 hours, ensuring the moisture content remains below 25%.
For a more intensive cleaning, you can create a paste by mixing two parts baking soda with one part vinegar. Apply this paste to the surfaces affected by calcium buildup and let it sit for about five minutes. Then, wipe off the paste with a damp sponge.
Additionally, you can try using freshly squeezed lemon juice, which is especially effective on metal surfaces like faucets. Simply put the juice in a spray bottle and apply it to the affected areas.

Bar Keepers Friend is a mild oxalic acid alternative
Bar Keepers Friend is an excellent alternative to Comet for cleaning stainless steel pans. It is a mild abrasive cleaner that can be used to brighten metal, remove rust, and clean tough stains and gunk. The product contains oxalic acid, which is a natural compound found in many fruits and vegetables, and works to shine up metal and remove rust. It also contains abrasives, which act as scrubbers, and detergents or non-bleach-containing cleaners.
Bar Keepers Friend has been around since the 1880s and is known for its effectiveness in cleaning stainless steel pans and surfaces. It is available in powder and pre-mixed liquid forms, with the powder being more suitable for scrubbing tough messes and the liquid for minor upkeep. The product is gentle on high-quality stainless steel and can be used to remove even the most stubborn stains and burnt-on food.
When using Bar Keepers Friend, it is important to follow the directions and test an inconspicuous spot first, as the oxalic acid can irritate the skin. A gentle rub is often more effective than applying a lot of pressure, and it is recommended to wear gloves during use. The product should not be left on the surface for more than a minute before scrubbing, as the acid can create spots or etch the surface.
Bar Keepers Friend is a versatile cleaner that can be used on various surfaces beyond stainless steel, including Pyrex, copper, brass, tile, ceramic, fiberglass, and chrome. It is a popular choice for cleaning bathrooms, yard tools, and even parts of cars or motorcycles. However, it should not be used on non-stick cookware or brushed stainless steel with a protective layer as it can scratch the surface.
Overall, Bar Keepers Friend is a safe and effective alternative to Comet for cleaning stainless steel pans. It is gentle, yet powerful enough to remove stains and burnt-on food, making it a popular choice for culinary enthusiasts.
