Although stainless steel isn’t one to get stained with ease, it’s still susceptible to staining from acid-based household cleaners.

Acidic household items like vinegar and citrus extracts are common in most households. The milder the acidic component of the cleaners and household items, the more damage they can make to your sink.

So, how do you remove acid stains from a stainless steel sink? You’ll find that out in a few.

Can Acid Damage Stainless Steel?

Yes, acid can damage your stainless steel sink. If it is spilled on the sink or any other stainless steel appliance, you need to rinse it off quickly.

Although stainless steel is an alloy of chromium that helps fight stains, it can get damaged if acid comes into direct contact with it.

An irreversible chemical reaction is formed when acid comes into contact with the stainless steel. It’s from this reaction that potential corrosion and damage arise.

The good news is that although the stains cause damage, it can still be treated.

How Does Stainless Steel Resist Corrosion?

Although stainless steel grades vary in manufacturing and metallurgic composition, a common trait is the passivation layer.

In simpler terms, the passivation layer is the coating of chromium oxide that is usually formed when the surface comes into direct contact with oxygen.

This layer gives stainless steel its finished texture and a variety of aesthetic options. It is also considered impermeable to water and protects the metal.

And although the layer can stain in case of extreme temperature changes, it still endures.

However, the layer doesn’t exempt stainless steel from corrosion. It can still get corroded under certain circumstances.

Can Vinegar Corrode Stainless Steel?

If you belong to the group of people who assume that stainless steel can stay for long without cleaning, you are in the wrong. You should know that the metal requires a regular cleaning routine.

Although it has a higher degree of resistance to stains than other metals, it can still get discolored and even corroded over time.

Therefore it’s not advisable to leave your stainless steel sink or appliance soaked in a solution containing chlorine, vinegar, or table salt for long as these can damage the metal.

Conclusion

There’s still hope for your stainless steel sink if it has been stained by acid. And more so, if you work on the stain immediately. With baking soda paste and a soft cleaning towel, you’ll get the job done in minutes.

To avoid working on stubborn stains (which take more time and energy to remove), work on your sink as soon as you notice the acid spill. And when doing so, wear protective gloves to prevent skin irritation.

If baking soda paste fails to work on the stain, use ammonia and liquid dishwasher solution instead. to know more visit wikihow.com
