One can see stainless steel surfaces in many industries as well as in daily life. So the question arises: which method is best for cleaning stainless steel?
Stainless steel is exactly as it says: stainless. In other words, it does not easily tarnish or corrode and it retains its shine. It is also prized for its strength at very high and very low temperatures. Therefore, it’s used for industrial applications from nuclear installations to factories and laboratories. Stainless steel is also common in restaurant kitchens and surgery rooms. One of its first consumer uses was for cutlery, notably manufactured in Sheffield, England.
Best way to clean stainless steel
Given its widespread use, what is the best way to clean stainless steel? Thanks to the alloy’s chromium content, a passive film protects the surface, making it easy to maintain. Start with the least aggressive option and escalate only if needed. Always wipe with the grain, then rinse with clean water and dry thoroughly to avoid water marks.
Soap and water
For routine care, a mild detergent with warm water works best. It removes light soil and the greasy film that can dull the surface. Rinse and dry with a microfiber cloth.
Ammonia and detergent solution
A 1% ammonia solution in water with a bit of neutral detergent helps remove fingerprints and light soiling. Proprietary spray polishes can also reduce future remarking. Ventilate well when using ammonia.
Stubborn stains & light tea-staining
Avoid harsh abrasives that can scratch. Instead, use non-scratching cream cleansers based on calcium carbonate or citric acid to lift discoloration and light rust (tea-staining). Work with the grain; rinse and dry.
Nylon abrasive pads
Nylon (non-metallic) pads help remove deposits such as paint or mud. Use with warm water or steam. Do not use steel wool or carbon-steel brushes, which can embed iron and trigger corrosion.
Oil and greasy marks
For high-touch areas (e.g., fridge doors in a restaurant or hotel kitchen prep area), hydrocarbon solvents such as methylated spirits, isopropyl alcohol, or acetone remove oily residues effectively without degrading the finish. Test in an inconspicuous area first, then rinse and dry.
Burnt-on food (cookware & trays)
For stainless-steel trays and cookware, soak in hot water with detergent to soften deposits. Then use a nylon brush and a calcium-carbonate scouring cream to remove remaining residue. Rinse thoroughly and dry to restore the stainless finish.
How to polish stainless steel
- Clean first: Remove dust, grease, and fingerprints using one of the methods above; rinse and dry.
- Choose a polish: Use a dedicated stainless-steel polish or apply a few drops of mineral oil to a microfiber cloth.
- Work with the grain: Apply light, even pressure along the brushing direction of the metal.
- Buff: Flip to a dry section of the cloth and buff until streak-free.
- Protect: For architectural profiles, consider a proprietary protective coating compatible with stainless steel to reduce future marking.
Tip: Avoid chloride-containing cleaners and never use bleach on stainless steel.
How to remove rust from stainless steel
- Identify the cause: Light surface rust (tea-staining) often comes from salt spray, standing water, or contact with carbon steel.
- Start mild: Try a paste of baking soda and water. Apply with a soft cloth following the grain; rinse and dry.
- Use approved cleaners: If stains persist, use a stainless-safe citric or oxalic acid cleaner. Follow the manufacturer’s dwell time, then rinse copiously with clean water and dry.
- Decontaminate: If contamination from carbon steel is suspected, use a non-metallic abrasive pad with a neutral detergent to remove embedded particles.
- Prevent: Rinse surfaces exposed to chlorides (coastal or poolside environments), design for drainage, and schedule periodic cleaning.
Cleaning stainless steel for lifetime durability
With the methods above, the appealing stainless steel sections by Montanstahl will endure. Whether you choose hot rolled profiles for a canopy, laser-welded profiles for a curtain wall, or cold rolled special stainless steel profiles for decorative purposes, regular maintenance preserves design quality and surface finish.
- Do: Wipe with the grain, rinse, and dry.
- Do: Test cleaners on a small, hidden area first.
- Don’t: Use bleach, chloride-heavy products, or steel wool.
