How to clean stainless steel profiles

Stainless steel profiles are an aesthetic, functional, and durable choice for all types of projects. At ATRIM, we recommend them not only for their strength and elegance but also because they adapt seamlessly to different architectural languages and usage conditions.

However, like any material exposed to daily use, their performance and appearance depend on proper care. That’s why in this article, we share the best cleaning and maintenance practices, common mistakes to avoid, tips based on environmental conditions, and key actions that make a long-term difference.

What type of stainless steel is used in profiles?

Stainless steel profiles used in architecture and design are commonly manufactured in AISI 304 stainless steel, an alloy containing approximately 18% chromium and 8% nickel. This composition makes it highly resistant to oxidation and corrosion in indoor or semi-covered environments.

For outdoor applications in harsh conditions, coastal zones, or industrial environments, AISI 316 stainless steel is recommended. This grade includes molybdenum to enhance resistance to chlorides and aggressive agents.

Key features of stainless steel

• High corrosion resistance thanks to its protective passive layer.

• Superior durability against UV rays, humidity, and temperature changes.

• Long-lasting visual appeal when properly maintained.

• Chemically inert—ideal for areas with food handling or cleaning products.

The most common finish for profiles is the satin (brushed) polish, which offers a refined, non-glossy look that better hides minor scratches and fingerprints.

Effective cleaning methods

1. Routine or periodic cleaning

• Use a microfiber cloth with warm water.

• Dry immediately to prevent water spots.

• Always wipe in the direction of the grain.

• Suggested frequency: weekly or as needed.

2. Stubborn stains or grease

• Mix: 1 liter of warm water + 3 drops of neutral detergent.

• Apply with a soft (non-metallic) sponge.

• Rinse with clean water.

• Dry with a soft cloth.

3. Limescale or hard water stains

• Mix: 1 part white vinegar + 3 parts water.

• Apply with a cloth, let sit for 5–10 minutes.

• Rinse thoroughly and dry.

• Tip: If your water is hard, use distilled water for the final rinse.

4. Restoring shine

• Use stainless steel-specific polishes.

• Apply with a cotton cloth, following the manufacturer’s instructions.

• In outdoor or coastal areas, repeat every 3 months.

Recommended products

Common mistakes when cleaning stainless steel

• Using products with chlorine → Chemically attacks the passive layer, causing pitting.

• Scrubbing with abrasive pads → Scratches the surface and traps dirt.

• Not drying after cleaning → Leads to water spots or limescale.

• Mixing different cleaning products → Can cause unpredictable chemical reactions and staining.

• Using undiluted vinegar or not rinsing → May leave marks or acid residue.

How to Prevent Damage During Construction

One of the most vulnerable times for profiles is during construction. Even if properly installed, they can suffer:

• Scratches from tools.

• Stains from adhesives, paint, or construction dust.

• Prolonged exposure to moisture, salt, or improper cleaning.

Recommendations:

• Cover profiles with protective film or wide masking tape immediately after installation.

• Avoid contact with mortar, adhesives, or silicone until fully cured.

• Clean immediately if contaminated with aggressive substances.

• Perform a final cleaning with warm water and neutral detergent at the end of the project.

Common applications of stainless steel profiles

• Residential kitchens: Combine hygiene with modern aesthetics.

• Bathrooms: Ideal for areas with constant steam and moisture.

• Retail stores: Withstand frequent cleaning and heavy foot traffic.

• Façades and exteriors: When using AISI 316, they remain flawless even in harsh environments.

• Hospitals and laboratories: Chemically inert and easy to sterilize.

Frequently Asked Questions (FAQ)

Can I use regular multi-purpose cleaners?
Not recommended. Most contain harsh chemicals like chlorine or ammonia.

What if the profile is already stained?
Try a deep clean with diluted vinegar or use specialized polishes.

Can stainless steel profiles rust?
Yes, if the protective layer is compromised or they’re exposed to chlorides without proper maintenance.

How can I tell if my profile is AISI 304 or 316?
Check with the manufacturer or supplier. At ATRIM, we always specify the stainless steel grade in our technical datasheets.
