How do you care for a composite granite sink?

With continued use, your granite composite sink will look dull or even develop some streaks. Knowing how to take care of it properly will help you keep it looking clean at all times.

Here are our top tips for caring for your granite composite sink:

1. Regular maintenance

Taking care of your granite composite sink isn’t hard as you might be thinking. You just need to wipe it with soapy water and sponge every day. You can also use a soft nylon brush in place of sponge. After wiping it clean, rinse it and dry it thoroughly to keep soap, water spots, and mineral deposits from giving it a dull look.

2. Removing tough stains

In case you notice that your sink has developed tough stains that won’t go away with regular cleaning, we suggest that you use common household cleaning products to work on these stains. A perfect example involves using mixing water and vinegar in 50:50 ratio and spraying the mixture on the stains. Alternatively, you can use baking soda and water to make a paste that you apply on the stains to get rid of them. Afterward, you can rinse your sink and then wipe it dry.

3. Tackling hard water stains

What if your sink has developed stubborn stains e.g. hard water streaks? In such case, then you’ll need a more powerful cleaning solution. We suggest applying a solution of water and bleach in 50-50 mix to the stubborn stains. After cleaning your sink with this solution, drench it with water and then wipe it dry.

WARNING: Avoid using harsh chemicals, cleaning solutions containing ammonia, or abrasive sponges/brushes as these can do long-lasting damage and discoloration of your granite composite sink. Stick to gentle cleaning solutions and tools.




What to look for before buying?

Here, we’ll discuss the essential factors to consider when looking for a granite composite sink for your kitchen.


Composite granite sinks are naturally durable. But that doesn’t mean you should check the quality of the sink you want to buy.

Make sure you check the composition of the material used to make your sink. As you might have discovered in our composite granite sink reviews above, top manufacturers use 80% granite sand and 20% resins as bonding agents to create extremely durable sink materials.

Additionally, make sure the sink is resistant to discoloration, stains scratches, chipping, impact, and can withstand high heats. All these aspects contribute to the sink durability.

Ease of maintenance

Another crucial factor to keep in mind when looking for the perfect sink involves easy cleaning/maintenance. The best sink should come with a silky, smooth, and non-porous finish to make cleaning as easy as wiping it with clean sponge. Non-porous surfaces are also great in that they don’t accommodate bacteria, giving you a more hygienic kitchen environment.


The two most common installation methods for granite composite kitchen sinks include topmount and undermount. The former is easy to setup as it doesn’t require any extra support underneath. Undermount sinks require you to setup excellent support underneath due to their heavy (stone) weight. They’re a bit harder to install than topmount sinks. Some units offer you both the drop-in and undermount options.


You’ll also need to check the aesthetics of the sink you plan to buy. Though these sinks are generally good-looking, you need to ensure the specific unit you pick has a design and appeal that suits your personal preferences and matches your countertop or kitchen décor.
