How to Remove Scratches and Maintain Stainless Steel Sinks

Updated: Mar 26

Stainless steel sinks are known for their long-lasting durability and are a great addition to any kitchen. However, just like with any appliances, they can be scratched over time from many different elements that come in contact with the sink. To preserve their appearance, stainless steel sinks require regular cleaning and maintenance. Here are a few tips on restoring and maintaining a stainless steel sink.

Before beginning, make sure to grab all the necessary tools below:

  • Microfiber cloth

  • Stainless steel polish

  • Scratch removal agent

  • Non-abrasive cleaner

  • Sanding block / Abrasive Pads

Clean the scratched area

The first step is to clean the area of the sink where the scratches are shown. Apply some non-abrasive cleaner such as dish soap or powder-based cleaner all over the sink with a soft sponge or cloth. Remember to rinse well after and dry with a soft cloth.

Define what type of scratches you’re dealing with

It is important to identify the type of scratches because using repair methods designed for other types of scratches may either be insufficient or overpowering, making the issue even worse.

Stainless steel sink scratches can be separated in two categories: minor and severe. For example, minor scratches can be concealed with the use of a stainless-steel polish. However, for more severe scratches, this is not the case.

Deeper scratches require extra care. Determine the direction of the grain and start sanding in one direction only and work in the direction of the grain.

It is important to never work against the grain as it will ruin the finish and make more irreversible damage. While sanding the scratches, keep in mind to not apply too much pressure as it might cause damage to the sink. Clean with a soft abrasive cleaner and a microfiber cloth.

Next, apply a small amount of scratch remover compound on a buffer and buffer until the agent is smoothed all over.

Depending on the severity of the scratches, you may need to repeat the process 3-5 times. Clean with a soft abrasive cleaner and a microfiber cloth.

Clean and polish

After removing all the scratches and unwanted marks, it is important to remember to polish the sink to maintain its shine. With a fresh and clean microfiber cloth, wipe down the area and remove all the metal dust and polishing agent. Always, always always, rub the cloth in the direction of the grain!

Now that we’ve taken care of the scratches, let’s move on to how to maintain that beautiful stainless steel sink.

It is important to note and avoid using abrasive cleaners such as scrub pads, steel wool, and bleach. Instead, use mild, non-abrasive cleaning agents like Bar Keepers Friend or vinegar.
