In this blog post, we will teach you how to remove chemical stains from stainless steel sinks using common household products. Follow these simple steps, and your sink will be looking good as new in no time!

What Is Stainless Steel?

Stainless steel is an alloy of iron, chromium and other metals. It is sometimes called “inox” steel (from the French word “inoxydable”) because it is resistant to corrosion. There are different grades and surface finishes of stainless steel produced to accommodate the environment in which the material will be used.

Stainless steel sinks are widely used in many homes as they are durable and easy to maintain.
However, over time they may start to show signs of wear and tear. One common issue that can occur is the development of stains from chemicals such as cleaners or bleaches. While these products are safe to use on other surfaces, they can cause damage to stainless steel. [1]

What Are The Benefits Of A Stainless Steel Sink?

A stainless steel sink is an excellent choice for the kitchen because it withstands wear and tear and is easy to maintain. Stainless steel is a corrosion and stain-resistant alloy made of iron, chromium, and nickel. It is also non-porous so it does not absorb dirt or bacteria.

What Are the Disadvantages of Stainless Steel Sinks?

However, stainless steel sinks can be susceptible to staining from certain chemicals.

What Are the Disadvantages of Stainless Steel Sinks?

This is because the chromium in the alloy can react with certain chemicals to form achromic oxide, which is a black or brown substance.

Types Of Stains And Corrosion

Hard Water

This is the most common type of stainless steel sink stain and is usually caused by a buildup of minerals, such as calcium and magnesium, in the water. The stains are usually white and show up as spots or streaks. They can be challenging to get rid of. [2]

Acidic Foods

Acidic foods, such as lemons, tomatoes, and vinegar, can cause corrosion of the finish on your stainless steel sink. This type of corrosion appears as a dull, dark stain on the surface of the sink.

Rust

Rust stains can occur if your stainless steel sink is exposed to iron or other metals. These stains appear as reddish-brown spots on the surface of the sink and are often difficult to remove.

Chlorine And Chlorides

Chlorine and chlorides, such as salt, can cause pitting and corrosion of the stainless steel sink. These stains appear as small, dark spots on the surface of the sink.

Bimetallic Corrosion

Bimetallic corrosion, or the process of two dissimilar metals oxidizing when in contact with each other, is most commonly seen between materials like stainless steel and copper. This type of corrosion can cause staining and discoloration of the sink.

Acid Staining

Acid staining is a type of corrosion that occurs when acidic liquids, such as coffee or tea, come into contact with the stainless steel sink. This type of corrosion can cause staining and discoloration of the sink.

Iron Staining

Iron staining can occur if your stainless steel sink is exposed to iron or other metals. These stains appear as reddish-brown spots on the surface of the sink and are often difficult to remove. [3]

A General Stain Removal Procedure for Stainless Steel Sink

  • Begin by cleaning the area with a mild detergent and water. If the stain is still visible, you can try using a non-abrasive cleaner or white vinegar.
    Rinse the area with clean water and dry it off with a soft cloth.
  • If the stain is still present, you can try using a slightly abrasive cleaner like baking soda or comet. Make sure to rinse the area well and dry it off afterwards.
  • For stubborn stains, you may need to use a stronger cleaner like CLR or Lime-A-Way. You should always test these cleaners on a small hidden area before using them on the entire stain.
  • Once the stain is gone, you can protect the area by polishing it with a stainless steel cleaner and protector.

Stainless steel sinks are a common sight in many kitchens and bathrooms. They are durable and easy to clean, but they can still be susceptible to staining from certain materials.

Getting Rid Of Calcium And Rust Stains

If your stainless steel sink is starting to show signs of rust or calcium buildup, you’ll need to take action to remove the stains. Fortunately, there are a few simple methods you can use to get rid of these unsightly blemishes.

One way to remove rust stains from stainless steel is to use a product called Bar Keepers Friend. This cleaner is specifically designed for removing rust and other tough stains from metal surfaces. Simply apply the cleaner to the stain and scrub it away with a soft cloth or sponge.

If your stainless steel sink has been stained by calcium deposits, you can try using vinegar to break down the buildup. Pour a small amount of vinegar onto the stain and let it sit for several minutes before scrubbing it away with a brush or sponge. You may need to repeat this process a few times to completely remove the calcium deposits.

Once you’ve removed the rust or calcium stains from your stainless steel sink, be sure to rinse the area well with water and dry it off with a soft cloth. This will help prevent new stains from forming in the future. [4]

For Hard-To-Remove Stains

Baking soda is a natural cleaning agent that can be used to remove hard-to-remove stains from stainless steel sinks. Pour a small amount of baking soda onto the stain and scrub it with a soft sponge. Rinse the sink with clean water and dry it with a soft cloth.

For Fresh Stains

Soak a clean cloth in warm water and vinegar solution. Place the cloth over the stain and let it sit for several minutes. Scrub the stain gently with the cloth until it disappears. Rinse the sink with clean water and dry it with a soft cloth.

For Stubborn Stains

Mix equal parts of baking soda and salt together to form a paste. Rub the paste onto the stain using a soft sponge. Rinse the sink with clean water and dry it with a soft cloth.

Vapor Cleansing Process

If you have a chemical stain on your stainless steel sink, the best way to remove it is through a process called vapor cleansing. This process uses high-pressure steam to remove the stain from the metal surface.

The first step in vapor cleansing is to apply a small amount of water to the stained area. Next, you will need to apply a generous amount of pressure to the water using a steam cleaner. The high-pressure steam will break down the chemical bonds that are holding the stain to the metal surface. After a few minutes, you should see the stain begin to lift off of the metal surface. Once the stain is removed, you can then rinse off the area with clean water.

Vapor Cleansing Process

Chemical etching is another method that can be used to remove chemical stains from stainless steel. This process involves using a strong acid to eat away at the stain. However, this method should only be used as a last resort, as it can damage the metal surface if not done correctly.

Alternative Methods To Remove Chemical Stains

If the chemical cleaner has not worked or if you are looking for alternative methods to remove the stains, here are a few things you can try:

Use Baking Soda

Baking soda is a natural cleaning agent that can be used to remove many types of stains, including chemical stains. To use this method, mix together equal parts baking soda and water to form a paste. Apply the paste to the stained area and scrub with a soft-bristled brush. Rinse away the paste with clean water and dry the area with a soft cloth.

Use Vinegar

Vinegar is another natural cleaning agent that can be used to remove chemical stains from stainless steel sinks. To use this method, mix together equal parts vinegar and water. Apply the mixture to the stained area and scrub with a soft-bristled brush. Gently rinse the mixture away with clean water and dry thoroughly with a soft cloth.

Use Lemon Juice

Lemon juice is another natural cleaning agent that can be used to remove chemical stains from stainless steel sinks.

To use this method, mix together equal parts lemon juice and water.
Use the mixture on the stained area and scrub lightly with a soft-bristled brush. To remove the mixture, rinse with clean water and dry thoroughly with a soft cloth. [5]

Use Cream of Tartar

Cream of tartar is another natural cleaning agent that can be used to remove chemical stains from stainless steel sinks. To use this method, mix together equal parts cream of tartar and water to form a paste. Apply the paste to the stained area and scrub lightly with a soft-bristled brush. Wash the area with clean water and dry completely using a soft cloth.

Use Rubbing Alcohol
