Stainless steel is an alloy of iron, carbon, and chromium. The chromium in stainless steel forms a thin layer of oxide on the surface of the metal, which is known as the passive layer. This passive layer protects the steel from corrosion. However, if the passive layer is damaged, corrosion can occur.
The higher the chromium content, the greater the corrosion resistance. Stainless steel rusting occurs when the passive layer is damaged and there is not enough chromium for it to reform. In order to prevent stainless steel from rusting, it is important to regularly clean and maintain the metal. Surface damage, such as scratches or dents, can also contribute to the degradation of stainless steel over time.

Chromium chloride layer on surface is self repairing
The chromium oxide layer on the surface of stainless steel is self-repairing, meaning that any damage to the passive layer will be repaired by oxidation. In other words, when exposed to oxygen and moisture, chromium in the stainless steel reacts with oxygen to form an invisible protective film. This prevents further corrosion from occurring as long as there is enough chromium in the alloy.
Therefore, it is important to use cleaning and maintenance methods that do not damage the passive layer. Never use corrosive products such as chloride cleaners, abrasive cleaners, or bleach on stainless steel surfaces.
How to properly handle stainless steel?
When working with stainless steel, it is important to take measures to prevent contact with corrosive substances. This will help to extend the service life of the stainless steel;
- Always wear clean gloves and use only stainless steel tools and components
- Avoid contact with carbon steels or iron
- Do not weld, cut, drill, or grind carbon steel near stainless steel
- Avoid contact with concrete detergents and chloride solutions
- Do not use steel wool or other abrasive scrubbing pads
10 Tips for Cleaning Stainless Steel Like a Pro

Selecting right Stainless Steel Cleaner is Important
Using the wrong cleaning products on stainless steel surfaces can cause irreparable damage and lead to costly repairs. To keep stainless steel looking shiny and new, it is important to use the right product for the job.
The best way to clean stainless steel is to use a mild detergent such as dish soap diluted in warm water, then use a soft cloth to wipe the surface. Be sure to rinse off all of the soap residue with clean water and dry the surface before applying any polish or wax.
Never use following products on stainless steel
Chloride Cleaners:
Chloride cleaners contain corrosive elements that can damage the protective layer on stainless steel surfaces.
Abrasive Cleaners:
Abrasive cleaners, such as those containing scouring pads, may scratch the surface of stainless steel and create an ideal environment for corrosion.
All-Purpose Cleaners:
All-purpose cleaners are not designed specifically for stainless steel surfaces, and can leave behind a residue that could damage the finish.
Chlorine Bleach:
Chlorine bleach is very corrosive and will cause permanent damage to stainless steel.
If you want to keep your stainless steel looking its best, use gentle cleaning products and avoid abrasives or harsh chemicals at all costs.

Are Home Remedies as good as Industrial cleaners for removing rust from Stainless steel?
The answer to this question is not a simple yes or no. Home remedies can be effective in removing rust from stainless steel, however it’s important to note that the effectiveness of these methods vary greatly depending on the severity of the rust and the quality of the stainless steel.
Industrial cleaners are often used because they provide a more consistent performance than home remedies, and they may also help protect the stainless steel from further corrosion.
Ultimately, it is up to you to decide which option will work best for your particular situation. If you are looking for a quick fix, then home remedies may suffice. However, if you want a more reliable long-term solution, then industrial cleaners would be a better choice.
Specific stainless steel cleaning
If your stainless steel is discolored or rusted, you’ll need to use a different cleaning method than usual. Below are some ways to clean tough stains;
Fingerprints
To clean those pesky fingerprints off of stainless steel, simply use soap and warm water. Dry off the surface with a microfiber cloth.
If the stains are particularly stubborn, you can use a commercially-available solution or hydrocarbon solvent to help remove them.
Oil and Grease Marks
For oil and grease marks, apply isopropyl alcohol, acetone or methylated spirit several times with a clean, non-scratching cloth until all marks are removed. Make sure to dry off the surface after cleaning.
Burnt-on stains
To remove burnt-on stains from stainless steel, use a metal brush or abrasive sponge. Start by scrubbing the area with warm water and detergent to loosen the stain before you start to scrub it off. Make sure to rinse off any residue after cleaning.
Discoloration
Discoloration on stainless steel can be removed by using a mild abrasive cleaner. Use the abrasive cleaner with a non-scratching cloth in circular motions to gently remove any discolorations or stains. After cleaning, rinse off the surface and dry it with a microfiber cloth.
Coffee Stains
Coffee Stains can be tackled by making a sodium bicarbonate solution (baking soda and warm water) and soaking the affected area. Once the stain has been removed, rinse off the surface and dry with a microfiber cloth.
Tea Stains
To remove tea stains from stainless steel, soak in a solution of warm water and mild detergent for 15-20 minutes before scrubbing with a metal brush or abrasive sponge. Rinse off any residue and wipe down with a microfiber cloth.
