How to Clean Granite Composite Sink: 4 Safe Steps!

You need to know how to clean granite composite sink if you have one in your home. Despite the benefits, you must know how to keep it stainless.

Granite is a natural stone and one of the most popular materials for sink fabrication today. It adds a touch of elegance to any kitchen setting.

Composite granite is made of three main components – crushed quartz, rock dust, and acrylic resin. This mixture is pressed into blocks of various shapes and sizes, or into pavers or slabs for flooring. The resulting material is about 90% stone and only 10% resin.

Composite granite sinks are beautiful, durable, and made of the highest-quality materials.

The resin used in these sinks is tight enough to ensure that the sink won’t break easily and is smooth enough to prevent scratches and other cosmetic damage. These sinks are excellent for any room in your home, especially your kitchen.

A granite composite sink is a kind of granite that is specially crafted with compartments that allow water to drain easily.

When talking about granite composite sinks, you have 2 choices: you can either make it match your current kitchen cabinets or choose custom pieces according to the needs of your sink.

Sometimes, sinks can be very dirty because they are exposed to stains from liquids such as fruits and vegetables, coffee, and wine. When they are too dirty, they can get cloudy.

Do you have granite composite sink at home and does it has stains? In this article, you’ll learn how to clean granite composite sink!

Benefits of using granite composite sink

1. Customizable

Granite composite sink is a great improvement to your kitchen or bathroom. A custom-made granite composite sink will fit perfectly into the layout of your bathroom. Granite composite sinks can be customized by using different colors and textures.

The texture and style of composite granite can be customized to look and feel like wood, marble, or any other type of stone.

This can be colored easily; you can get pigmented colors with different tones.

The beauty of composite granite is that it allows your creation to have the look of just one material rather than a blend like concrete mixes.

2. Stain resistant

Granite is a composite of different substances, such as quartz, feldspar, and hornblende. Since it’s made out of different substances, the granite sink is extremely resistant to stains.

The smoothness of this type of material makes it easy to wash and keep clean. Also, with the additional advantage of being stain-resistant to coffee, juice, and more, it’s often a better alternative than natural stone.

3. Cost-efficient

One of the best things about a granite composite sink is its total cost. Compared to the original granite sink, it’s so much more cost-effective. In fact, it can help you save as much as 40%. So if you are tight on budget, this is a great alternative to consider.

The disadvantage of using granite composite sink

1. It is not 100 % original

It can be argued that original and genuine items are better than their alternative.

For example, using original granite in the sink is sometimes a better choice than using a composite granite sink. The original is usually more expensive than the latter, but it is often a worthwhile investment.

2. It is heavy

Composite granite is usually heavier than the original one.

Composite granite is a mixture of natural stone dust and resin, which is stronger than the original one.

You should be aware if this is problematic for your home or if you cannot transport it to your home. Installing composite granite can be a difficult process and it’s recommended that you use a professional to install it.

3. It is unforgivable

The composite sink comes with a few drawbacks. The most obvious of which is that it is heavier than the original sink design, so you can’t move it around as easily.

If you accidentally drop a glass bowl or plate, the weight of the composite sink could cause it to break much more easily than the same items if they were dropped in an original sink. If you are installing this type of sink, you have to be careful when washing the dishes.

How to clean granite composite sink

1. Use dishwashing soap

If you want to clean a granite composite sink, you can use dishwashing soap.

You can clean it by pouring some dishwashing liquid into it and rubbing it with a sponge or toothbrush. Next, rinse it with water.  Don’t forget to wipe it down until the surface is completely dry.

It’s always good to keep a microfiber cloth or towel nearby because you do not want to scratch the surface of the sink while cleaning it.

It is crucial to clean any soap leftovers in a granite composite sink. If you do not clean it properly, the soap may cause bacteria growth and a foul smell.

2. Vinegar and baking soda

You can use a mixture of vinegar and baking soda to clean a granite composite sink. The mixture of baking soda and vinegar can soften the stains on a sink and make them easier to get rid of.

First, you can fill the sink up with warm water. Then, sprinkle a layer of baking soda onto the water.

Add a little vinegar on top of the baking soda.

Then, mix the baking soda and vinegar together into a colored foam. You can scrub the colored foam onto your sink and then rinse it off with warm water afterward.

3. Lemon water

One of the simplest and most effective ways to clean a sink is with lemon water.

The strong acidic flavor of lemon is one of the things that can make it great for cleaning objects and surfaces.

Cut a lemon in half and squeeze its juice into the sink. Then, take a toothbrush and brush it over the sink. Finally, rinse it all off with some water.

4. Use polish

Cleaning your granite composite sink can be tricky because of the material it is made of – stone. By using polish on your sink, you will be able to keep the surface clean for a longer period of time.

Polish will simply create a buffer between the stains and the actual layer of your sink, which would otherwise get damaged by the acidity of the food.

You can buy specific polish for granite composite sinks, and you should always use the polish when the sink is dry.

How to keep granite composite sink last longer

1. Avoid throwing boiling water

You should never throw boiling water into your sink. The reason for this is that the granite composite isn’t designed to withstand high temperatures, so it could melt or crack if you make this mistake.

Boiling water is dangerous for your granite composite sink and should be avoided at all costs.

2. Avoid using harsh chemical ingredients

There are plenty of chemical ingredients that could be harmful to your sink, as many commercial cleaning products are harsh on the materials. If you care about the maintenance of your sink’s material, you should make sure you never use harsh chemical ingredients to clean it.

If you have already used these chemicals, don’t fret. Instead, use a non-abrasive cleaning method such as baking soda-detergent solution or vinegar-water solution to clean your sink.

3. Keep it dry

When you overuse and don’t clean your sink properly, it can start to chip off. And if that happens, the sink will look worse for wear. The seal and coatings deteriorate, causing the sink to look no good.

Always wipe your sink dry and don’t leave water on it overnight. If you ever notice any droplets of water after you’ve used it, be sure to wipe them off immediately in order to prevent any water damage and staining.

4. Avoid cleaning it with hard things

When cleaning your granite composite sink, you shouldn’t use hard things such as wire sponges, or metal brushes to clean it.

Avoid using anything harsh or abrasive that can damage the surface. The scratching from these metal objects could damage the color of your sink, and it could change the color of your sink.
