Easy Peasy: How to Clean a Granite Composite Kitchen Sink

Granite composite sinks are a popular choice for many homeowners because they are durable, scratch-resistant, and easy to maintain. However, they also require some special care to keep them looking their best and prevent stains, limescale, and water spots. Here, we’ll show you how to clean a granite composite kitchen sink using simple and natural methods that won’t damage the surface or the environment! 

What is a Granite Composite Sink?

A granite composite sink is made from a mixture of granite and acrylic resin, which gives it a smooth and non-porous surface. Some sinks might also be made with a blend of granite stone dust and acrylic resins. It’s a minor point, but I figured it is worth specifying for accuracy.  Granite composite sinks come in various colors and styles, and they can resist high temperatures, impacts, and acids. However, they are not immune to dirt and stains, especially if they are not cleaned regularly or properly.

How to Clean a Granite Composite Kitchen Sink: Daily Cleaning

The best way to keep your sink nice is to perform a daily cleaning routine after every use. This will help you remove any dirt, food particles, or residue before they have a chance to stick or dry on the surface of your sink. Here are the steps for daily cleaning:

• Rinse your sink with warm water and use a soft sponge or cloth to wipe away any debris or spills.
• Apply a few drops of mild dish soap to your sponge or cloth and gently scrub the entire surface of your sink. Avoid using harsh or abrasive cleaners that can damage the finish of your sink.
• Rinse your sink again with warm water and make sure there is no soap residue left behind.
• Dry your sink with a soft towel or cloth to prevent water spots and limescale formation.

How to Clean a Granite Composite Sink: Deep Cleaning

If you notice any stains, limescale, or water spots on your granite composite sink, you may need to perform a deep cleaning once in a while. This will help you restore the shine and beauty of your sink and remove any stubborn dirt (No harsh chemicals required!). Here are some natural and effective methods for deep cleaning your granite composite sink:

• Baking soda and vinegar: This is a classic combination that can tackle almost any stain or dirt on your sink. Sprinkle some baking soda over the wet surface of your sink and spray some white vinegar over it. The mixture will fizz and foam, which will help loosen and lift any dirt or stubborn stains. Use a soft sponge or brush to gently scrub the surface of your sink. Rinse well with warm water and dry with a towel or cloth.
• Lemon juice and salt: This is another natural method that can help remove stains and limescale from your sink. Cut a lemon in half and sprinkle some salt over it. Rub the lemon over the stained or scaled areas of your sink. The acid in the lemon juice will help dissolve the stains and limescale, while the salt will act as a mild abrasive. Rinse immediately and rinse well with warm water and dry with a towel or cloth.
  • Lemon Juice Caution: While lemon juice is often recommended for cleaning due to its acidic nature, using it on granite or granite composite surfaces frequently can cause damage over time. This is because the acidity can etch the surface. I thought it’d be good to include a word of caution about this. 
• Mineral oil: This is a simple way to add some shine and protection to your granite composite sink. Apply a thin layer of mineral oil to a soft cloth and buff it over the surface of your sink using circular motions. The oil will create a barrier that will repel water and prevent stains and limescale from forming. Wipe off any excess oil with another cloth.

Importance of Cleaning Your Composite Granite Sink

Cleaning your granite composite sink is not only important for hygiene and aesthetics but also for preserving its quality and longevity. If you neglect to clean your sink, you may notice some of the following problems:

• Stains: Granite composite sinks can absorb liquids such as coffee, wine, or oil, which can leave behind unsightly stains that are hard to remove.
• Limescale: Hard water can cause mineral deposits to build up on the surface of your sink, which can make it look dull and cloudy.
• Water spots: If you don’t dry your sink after each use, water droplets can evaporate and leave behind white marks that can affect the shine of your sink.
• Scratches: Although granite composite sinks are scratch-resistant, they can still get damaged by abrasive materials or sharp objects. Scratches can also make your sink more prone to staining and bacteria growth.

How to Prevent Damage to Your Granite Composite Sink

Besides cleaning your granite composite sink regularly, there are some other things you can do to prevent damage and keep it in good condition. Here are some tips:

• Some manufacturers might recommend sealing granite composite sinks periodically to protect against staining and other potential damage. 
• Avoid using abrasive materials or sharp objects on your sink. Use soft sponges, cloths, or brushes for cleaning, and avoid steel wool, scouring pads, or knives that can scratch the surface of your sink.
• Avoid exposing your sink to extreme temperatures. Do not pour boiling water or place hot pots or pans directly on your sink. Use a trivet or mat to protect the surface from heat damage.
• Avoid leaving acidic or staining substances on your sink for too long. Rinse off any spills of coffee, wine, vinegar, lemon juice, or other acidic or staining liquids as soon as possible. Do not leave metal utensils or cans on your sink, as they can cause rust stains.
• Not only acids but also strong alkaline (base) solutions can damage granite composite. Therefore, both extremes should be avoided. 
• Avoid using bleach or ammonia on your sink. These chemicals can damage the finish and color of your sink and cause it to fade or discolor. Use mild and natural cleaners instead.
