How to Clean a Granite Composite Kitchen Sink: Care Guide

If your granite composite sink looks dull and grimy, it is time to clean and shine it back to its original luster. Granite composite sinks are durable and beautiful, but they require some occasional TLC beyond normal daily cleaning. Your composite granite sink is made of a mixture of granite stone dust and acrylic resin, which makes it durable and resistant to scratches and stains. But, that doesn't mean that it will never become dull or stained.

 

To clean a granite composite kitchen sink, wipe the entire sink down with a soft, damp cloth or sponge and some mild dish soap. Avoid using abrasive cleaners or sponges, as they can scratch the sink's surface. 

 

If you need to remove tough stains, food stains, or build-up, make a paste using baking soda and water or a mixture of hydrogen peroxide and whiting powder. Apply the paste to the stain, let it sit for a few minutes, then scrub gently with a soft-bristled brush or sponge.

 

It's important to avoid using certain cleaning products on a granite composite kitchen sink, as they can cause damage to the surface. For example, avoid using bleach or ammonia-based cleaners, which can cause discoloration and damage the finish of the sink. 

 

Also, avoid using abrasive materials like steel wool or scouring pads, as they can scratch the sink's surface. With the right cleaning products and techniques, you can keep your granite composite kitchen sink looking clean and new for years.

Preventing Water Spots and Stains

Dry the sink after each use to prevent water spots and stains from forming on a granite composite kitchen sink. This can be done with a soft cloth or a microfiber towel.

 

Another way to prevent water spots is to use a water softener. Hard water can leave behind mineral deposits that can be difficult to remove. A water softener can help reduce the amount of minerals in the water, preventing water spots from forming on the sink.

 

In addition to wiping the sink dry after each use, it is important to avoid leaving standing water in the sink. This can lead to water spots and stains on the sink's surface.

Dealing with Tough Stains and Deposits

A granite composite kitchen sink is designed to be highly durable and resistant to scratches, stains, and heat. However, over time, even the toughest sinks can develop tough stains and deposits that can be difficult to remove. Here are some tips to help you tackle tough stains and deposits in your granite composite sink.

Removing Hard Water Stains

Hard water stains are a common problem in many households. These stains are caused by the buildup of minerals in the water, such as calcium and magnesium, which can leave unsightly spots on your sink. You can try using mild dish soap and warm water to remove hard water stains. 


If this doesn't work, you can use a mixture of baking soda and water to create a paste. Apply the paste to the stained area and let it sit for a few minutes before scrubbing it away with a soft sponge. 


Alternatively, you can dissolve the minerals with white vinegar or lemon juice. Simply apply the vinegar or lemon juice to the stained area and let it sit for a few minutes before rinsing it away with warm water.

Food and mineral deposits can leave unsightly stains on your sink that can be difficult to remove. To tackle these deposits, start by clearing the sink of all food or plates.

For mineral deposits, you can try using a mixture of hydrogen peroxide and baking soda. Apply the mixture to the stained area and let it sit for a few minutes before scrubbing it away with a soft sponge.

Using the Right Cleaning Agents

When cleaning your granite composite sink, it's important to use the right cleaning agents. Avoid using harsh chemicals or abrasive scrubbers that can damage the surface of your sink. Instead, opt for mild dish soap and warm water, or a specialized granite composite sink cleaner. 


Be sure to read the label of any cleaning product you use to ensure it is safe for use on your sink. Also, avoid using boiling hot water on your sink. Granite composite sinks are heat resistant but can't withstand hot pans or boiling water. The acrylic resin used to construct the sink could warp or melt.

Deep Cleaning Procedures

Creating a Deep Cleaning Solution

To achieve the best results when deep cleaning a granite composite kitchen sink, start by creating a gentle yet effective cleaning solution. Mix warm soapy water, using a mild dish soap, in a basin or bucket. This solution will serve as the primary cleaner for the sink's surface.

Techniques for a Thorough Clean

When applying the cleaning solution, use a nylon brush to scrub the sink in a circular motion, ensuring that the entire surface is covered. 

 

For tougher stains, create a thick paste using equal parts baking soda and water. Apply the paste directly onto the stained area and let it sit for 10-15 minutes before rinsing it off with warm water. This technique can help to lift and remove stubborn stains effectively without damaging the sink's surface.

 

For stubborn stains, here is a list of products that are safe for composite granite sinks:

 

Once the sink is thoroughly clean and all stains are removed, restore your sink's luster by using mineral oil. Using a soft microfiber cloth, gently buff a small amount of mineral oil into the surface using a circular motion. Allow it to sit for a few minutes, and then wipe away.

Preserving Your Sink's Longevity

Granite composite kitchen sinks are a popular choice for many homeowners due to their durability, beauty, and supreme surface. However, to keep your sink in good shape for the long run, proper care is essential. Here are some tips to help you preserve your sink's longevity.

Avoiding Common Damaging Practices

To avoid damaging your sink, it's important to avoid using harsh chemicals or abrasive materials such as steel wool. These can cause scratches or discoloration that will mar the beauty of your sink. Instead, opt for mild dish soap and a soft sponge or cloth to clean your sink.

 

It's also a good idea to avoid leaving standing water or food particles in your sink for an extended period. This can cause staining or even mold growth, which can be difficult to remove. To prevent this, rinse your sink thoroughly after each use and dry it with a soft cloth.

 

Never place a hot pot or pan in your sink. The extreme heat can warp the surface.

Routine Care for Lasting Beauty

Routine care is essential to keep your sink looking beautiful for years to come. To maintain its shine, wipe your sink down with a mixture of water and white vinegar once a week. This will help remove any water spots or mineral buildup that can dull the surface.

 

For tough stains or buildup, you can use a non-abrasive cleaner from the list above or a Mr. Clean® Magic Eraser® with either water or a 50/50 white vinegar and water solution. Be sure to towel dry with a cotton cloth to prevent water spots.

 

In the event that your sink does become damaged or stained beyond repair, it may be time to consider a new sink. With proper care, however, your granite composite sink can last for many years and provide you with a beautiful and functional addition to your kitchen.
