Stainless Steel, What is it?

A metal alloy is ordinary steel. The primary component is iron, and it contains 2 percent carbon with few other elements in trace amounts. These are phosphorous, silicon, oxygen, and sulfur.

To create stainless steel, manufacturers include the alloy, a fair amount of chromium ranging around 10 to 30 percent. There is also an addition of other elements, such as manganese and nickel.

This addition is to increase workability and durability. Due to this combination, stainless steel is usually considered non-magnetic.

Chromium combines with oxygen and forms chromium oxide. Basically, chromium is a super-hard metal.

It’s a compound for a continuous and thin layer on the stainless steel surface, and it prevents iron rust or ferric oxide from forming.

In this way, corrosion is also prevented. The layer can be regarded as a self-healing layer that handles the stainless steel sink even if the metal receives a scratch.



Stainless steel sink also receives stains. Stains happen. However, these stains are removable, and you can enjoy the former glory.

Like all other appliances, knowing the methods and steps to keep your stainless steel sink clean is helpful.

Maintaining on a daily basis saves you from exerting a lot later in cleaning and ensuring the sparkle is back.

Rinse your sink after each use; it will eliminate acidity or harsh chemicals from causing stains on the stainless steel sink surface.

Hope the above guidelines help in removing chemical stains from the stainless steel sink. Enjoy the long life and luster of your steel sink as a proud owner.
