You buy a stainless steel sink, hearing that it doesn’t rust. But after some time, you see things going a bit differently.
You note small rust spots showing up.
These are caused due to certain factors.
In this guide, we’ll help you understand why stainless steel rusts.
Plus, we will also help you understand how to get rid of it.
What is Stainless Steel?
Stainless steel is a mixture of different elements.
These elements include carbon, chromium, nickel, sulfur, and nitrogen.
Usually, stainless steel doesn’t rust.
This is because chromium and other elements form a layer on it, which provides rust resistance.
However, due to some reasons, rust can be generated on stainless steel sinks.
This can make the sink feel old and stained. Let’s see the factors that cause rust on stainless steel sinks.
What Causes Rust on Stainless Steel Sinks?
Metal Particles from Other Materials
As mentioned earlier, stainless steel sinks usually do not rust.
However, any other materials or components attached to them can.
For example, if the sink drain contains other metals, those can rust and leave stains around the drain.
It’s important to remember, however, that in these cases, the rust will be quite limited around the specific non-stainless-steel parts.
Cleaning the Sink with Harsh Materials
Using harsh materials to clean the sink can also ultimately cause it to rust.
The reason for that is that the harsh materials can eat away at the protective chromium layer, exposing the iron underneath.
When the iron reacts with oxygen from the air and water, it can rust.
Reaction with Hard Water Minerals
Hard water contains excessive iron and calcium, which can leave deposits behind.
When iron deposits react with oxygen, they form rust-like stains on the sink surface.
Homes that have old pipes often face these problems.
It is important to remember it’s not the sink that rusts. It’s iron particles that stick on the stainless surface.
Low-Quality Stainless Steel Sinks
Remember that quality matters a lot.
High-grade kitchen sinks are often 304-grade stainless steel. They contain more chromium and nickel. This makes them resistant to rust.
However, low-cost sinks have some different results.
They usually use 200-series steel. It can rust easily due to lower corrosion resistance.
How to Remove Rust from Stainless Steel Sinks?
We’ve mentioned some causes for rust above. But, once the rust shows up, what should you do about it?
Below, we’ve listed some methods that you can follow to clean the sinks and make them look new again.
Baking Soda Paste
Baking soda is a mildly abrasive material.
So, it will not scratch and damage the stainless surface.
Baking soda dissolves in hard water and removes rust particles that come from other metals.
Let’s see how to do it.
- Mix baking soda with some quantity of water.
- Make sure to mix until you get a thick paste.
- Apply the paste over the rusty surface.
- Let it sit for around 10 minutes.
- Use a soft brush or sponge and scrub the surface gently.
- Wash it with warm water and dry it later.
White Vinegar Spray
White vinegar contains acetic acid. It reacts with iron and breaks down rust stains.
It’s useful when rust is caused by hard water or iron particles from old pipes.
Here’s how you can use it.
- Fill a bottle with white vinegar.
- Spray gently on the rust spots.
- Let it sit for 5-10 minutes.
- Clean the spray with a soft cloth.
- Wash and dry the sink.
Commercial Stainless Steel Rust Remover
If homemade products do not work properly, you can go for commercial stainless steel rust removers. These removers have stronger and faster results.
But it is important to choose the right material.
You can use them by following the steps below.
- Read the instructions on the product label.
- Apply the remover with a soft cloth.
- Avoid using steel wool. It can damage the chromium layer.
- Wash the sink properly after applying.
- Make sure to dry after cleaning.
Tips to Prevent Rust in the Future?
Using products can help remove rust particles. But not handling it properly can cause it again. Therefore, here are some simple tips to avoid rust.
These tips can also make your sink feel fresh.
- Make sure to clean your sink after dishwashing.
- Dry the sink properly with a soft cloth to avoid water standing.
- Make sure not to leave cast-iron or metal pans in the sink overnight.
- Make sure to avoid steel wool. They can damage the chromium layer.
- Make sure to use safe cleaning products.
Final Thoughts
Stainless steel sinks do not rust on their own.
However, rust often shows up due to outside particles, hard water minerals, or cleaning mistakes.
With the right strategies, you can easily remove rust and give your sink a new look.
So, whenever you see brown-orange spots, don’t panic.
Most rust stays only on the surface or surrounds the drain cleaner. By following this guide, you can make your sink feel fresh and prevent it from rusting.
FAQs
Stainless steel sinks usually do not rust on their own. However, some factors, like hard water minerals, using hard or harsh materials, or outside particles, can cause rust.
Of course. You can easily remove rust from a stainless steel sink by using a baking soda paste, white vinegar spray, and commercial stainless steel rust removers.
You can simply mix baking soda with a few drops of water. After mixing, you will get a thick paste. You can apply it to the rusted surface. Make sure to let it sit for a few minutes. Then scrub it gently and wash the sink.
