Can You Use Bleach on Stainless Steel?
No, bleach should not be used on stainless steel. The chlorine in bleach can damage the protective chromium oxide layer that gives stainless steel its corrosion resistance, leading to pitting, discoloration, and rust. Use stainless steel cleaners or mild dish soap instead.
Key Takeaways
- Stainless steel gets its name from the passive chromium oxide layer that forms on its surface and protects it from corrosion.
- Brief, diluted bleach contact during sanitizing may not cause immediate damage but should still be avoided.
- Some industrial stainless steel grades have better chlorine resistance, but household appliances typically use standard grades.
Explanation
Stainless steel gets its name from the passive chromium oxide layer that forms on its surface and protects it from corrosion. Chlorine-based cleaners like bleach attack this layer, compromising the steel's stain resistance.
Damage from bleach may not be immediately visible but can manifest as pitting, rust spots, or discoloration over time. Once the protective layer is compromised, the damage is difficult to reverse.
For cleaning stainless steel, use warm water and dish soap for regular cleaning, or specialized stainless steel cleaners for tougher jobs. Baking soda paste can address stubborn stains. Always wipe in the direction of the grain and dry thoroughly.
Things to Know
- Brief, diluted bleach contact during sanitizing may not cause immediate damage but should still be avoided.
- Some industrial stainless steel grades have better chlorine resistance, but household appliances typically use standard grades.
- Vinegar is mildly acidic and generally safe for stainless steel in small amounts.
