How to Refinish a Scratched Black Kitchen Sink

Black Kitchen Sink

The lustrous coating of a black kitchen sink can appear hazy after a long time of wear and tear. Once you notice the gleaming shine on your acrylic, composite, or granite black sink diminishes, it’s your cue to conduct a restoration process. Usually, the black kitchen sink is susceptible to scratches when they’re not maintained correctly.

Using abrasive or harsh cleaning pads can also cause scratching to the finish. You can, however, get your hands dirty and refinish your sink, thanks to the below step-by-step guide on refinishing scratched black kitchen sinks. Before delving into these steps, let’s first look at why black sinks get scratched.

Do Black Sinks Get Scratched?

Even though most sinks are made from durable materials, unsightly marks and nicks can appear on them after prolonged use.

Since the composite sinks are not scratch resistant, they quickly get scratched by various items exposed to them. The most common cause of scratches on black sinks include;

  • Nonchalantly, putting sharp objects on the sink. Their edges make them perfect for scratching and damaging the sink.
  • Chlorine-based bleaching agents can be detrimental to your sink.
  • Abrasive cleaning pads. When you continually use them on your sink, they can cause scratches.

Therefore, you must be extra careful when placing utensils on the sink, especially sharp objects like knives.

Moreover, kitchen users should use only friendly cleaning pads that won’t scatter the sink coating. Now, let’s head on to the steps on how you can repair a deep scratch in a kitchen sink.

Steps Involved in Refinishing a Scratched Black Kitchen Sink

The process is simple and easy to do. Roughly, you’ll take about 30 to 40 minutes on the project. It’s basically part of the maintenance process.

Therefore, you need the area cleaned and ready for the next phase, removing scratches from a black kitchen sink. You must gather all the utilities required in the process before starting. What do you need?

Step 1: Tools Required

Start by gathering all the materials and essential tools needed to fix scratches on a black kitchen sink beforehand.

It’ll prevent unnecessary halting of the project. You’ll require three main tools: paper towels, creamy non-abrasive cleaners, and cleaning pads.

Moreover, you’ll need some utilities. They’ll include; mineral oil, mild dishwasher detergent, water, and quality surface cleaners, which can restore a black sink. After gathering all essentials, you’ll move to the next stage.

Step 2: Empty Your Sink

Remove any utensils that might be on your sink. Wash any dirty utensils to ensure the sink is empty. The greasy ones will require thorough washing with hot water, and dry them with a cloth. After clearing the sink, you can proceed to clean it.

Step 3: Sink Cleaning 

Once the sink is clear of utensils, you’ll want to clean it too. You’ll scrub around the black sink using mild detergent and a non-abrasive cleaning pad.

The non-abrasive cleaning pad will prevent further damage to your sink. When washing your black composite sink, you should avoid some cleaning detergents.

These cleaning agents have ingredients that can react with your sink’s chemical components causing damage beyond repair. They include; lemon, acid, alcohol, and vinegar, together with course solvents.

A deep cleaning helps remove hard-to-remove stains from hard water, grime, and debris. It’ll also enhance its performance. Once all cleaning is done, cover the areas you’ll not restore with an adhesive tape.

Step 4: Smearing Baking Soda Paste

Get your baking soda, then mix it with warm water to create a paste. Once the thick paste is formed, smear it around your black composite sink. Allow it to sit still on there for 12 hours. 

Baking soda is essential in removing black sink scratches and stains from your black composite sink. Once the 12-hour mark elapses, rinse the area with cold water, then allow it to dry. 

Step 5: Buff Dry your Black Composite Sinks

If your sink has minor scratches or burns, you’ll need to buff dry it. Basically, you’ll take your mineral oils and polish your sink to maintain its appearance. The buffing process is done before applying a sealer to the sink. 

  • It’s a straightforward process; you’ll first soak vegetable or mineral oils on a paper towel or a soft cloth.
  • Gently polish the sink, working your way throughout the area to attain an improved finish.
  • Leave the mineral oils to sit still for about 20 minutes, then go in and remove the excess oils with a soft cloth or paper towel.
  • At this stage, you’re ready to move to the next stage. However, if you notice that the area isn’t well polished, you can repeat this process.

Step 6: Resealing the Sink

To remove scratches in a black kitchen sink, you’ll need to clean it to remove debris. Ensure you cover areas you’re not working on with adhesive tape to prevent sealants from getting in contact with them. Apply the sealant to the sink. It’ll pretty much work effectively on a dry surface.

Deep Scratches and Burn Marks 

If you’re trying to get rid of deep scratches and burn marks on the sink surface, you’ll use scratch removers. Ensure you contact your manufacturer to determine the proper scratch remover for your sink. 

For example, if it’s made of porcelain, you’ll use a pumice stone. On the other hand, if you have a stainless-steel sink, you’ll need scratch removers made for that material.

Identifying the Grain of your Sink

Look keenly at the sink to determine the sink’s grain. It’ll help you determine which direction the lines are running towards. 

Get the Scratch Remover on Top of the Mark

The remover must come with a grid pad. With the help of an instructional guide, spray enough scratch remover to the pad. Scrub the sink using the grit pad on the affected areas.

You’ll then scrub the sink, moving toward its grain direction. Moreover, you’ll need to apply enough pressure on the sink to remove the marks. 

Buffing

The project’s next phase is buffing the remaining marks on the sink with a lighter pad on the scratch remover kit.

The process is different depending on the material of the sink. If the instructional guide directs you to add water while buffing the marks, then do so. Refer to the instructions on how you’ll go about the buffing process.

Rinsing 

After buffing out the sink, you’ll then rinse off the remover. Use a microfiber cloth that’ll allow you to buff off the remaining remover. You can use water to help you get rid of it completely.

Pro Tip:

To maintain that lustrous coating on your kitchen sink for a long time, you’ll always need to wash your utensils as soon as they hit the sink to prevent scratching and staining. Moreover, ensure you clean and wipe the sink dry after use.

Conclusion 

Kitchen users can never get enough of the lustrous black coating on their sinks. It improves the outlook of the entire kitchen when they’re maintained well. They’re, however, vulnerable to scratch and burn marks. 

Therefore, you must understand how to refinish a scratched black kitchen sink to restore it to its original nature effectively.

You can easily upgrade the entire ambiance of your kitchen when you refinish your black sink with the above steps.
