It does not develop many stains, which makes cleaning easier. Finally, it is not subject to discoloration and, if properly cared for, can add a touch of elegance to the kitchen. Therefore, it doesn’t take much effort to clean a granite sink: in this guide, we will show you how to do it anyway. So let’s see how we need to proceed in detail.

How to Clean a Granite Composite Sink?

  • Gentle cleanser
  • White vinegar
  • Abrasive sponge
  • Sodium bicarbonate
  • Abrasive powder

Clean with a mild detergent

Wear a pair of rubber gloves to protect your hands from cleaning agents. Clean the sink with a mild detergent and warm water, using a soft abrasive sponge or a soft nylon brush to remove even stubborn dirt and encrustations. Be sure to scrub the entire sink for a thorough cleaning, remembering to also clean the drain area and taps, where dirt and mineral deposits tend to accumulate. Rinse thoroughly with warm water to remove all traces of detergent.

Remove the limescale

An important step for a good cleaning of a granite sink is the removal of limescale. As with all other materials used to make sinks, limestone can also deposit in large quantities on granite, particularly where the water’s mineral content is high. Limestone causes the sink to lose its luster, making it look older and less attractive from an aesthetic point of view. A solution of white vinegar and hot water can help solve the problem: mix one part of white vinegar with one part of warm water in a spray bottle and spray the solution evenly over the entire surface, leaving the product to act for 10- 15 minutes. Then use a soft cloth to remove any dirt and stains that may be present.

Use baking soda

If despite this, you still notice some stubborn stains, the best solution for this type of material is to use baking soda. Make a fairly consistent paste consisting of baking soda and water, applying it to the stains, and rubbing it gently with a soft cloth. Let the paste act for about 10 minutes, then always rinse with lukewarm water. Avoid leaving wet abrasive sponges, cloths, or containers on any part of the sink to avoid further limescale build-up.

Clean daily with diamond dust

After cleaning the granite kitchen sink following one of the methods we have described in the previous paragraphs, it will be necessary in any case to preserve the correct hygiene and cleanliness of the kitchen every day. For daily cleaning, therefore, spread a little diamond abrasive powder on the granite kitchen sink. Then moisten a cloth and wipe it all along with the sink, rubbing lightly, thus avoiding scratching or deteriorating the surface itself. This everyday trick will allow you to remove all water spots and dirt and extremely effectively remove all surface scratches and stains that may have formed on the granite kitchen sink.

Removal of stubborn stains

Dirty dishes, food, and drinks lead to the formation of stubborn and difficult to remove stains. Alcohol and bleach help eliminate these stains that spoil the aesthetics of sinks and lead to unpleasant odors in the long run.

Several reasons generally produce stubborn stains. Let’s try to see the most common ones to understand how to solve these problems.

Food coloring

This type of sink has antibacterial protection and therefore very hygienic, but this does not mean that cleaning must be neglected, especially in the case in which dirty pots are left for hours in the tub or food coloring and drinks such as ketchup, chocolate, coffee, tea, wine, vinegar, and juice. In the long run, this type of product creates encrustations and releases bad smells, so it is always better to be careful and clean the sink immediately as soon as these products come into contact with the surface. These stains should be removed simply with dish soap and hot water.

Rust spots

Rust stains are formed due to iron particles that come into contact with the sink and are generally deposited due to metal utensils left too long on the surface and the use of detergents unsuitable for this type of sink. Another cause of this phenomenon is water passing through pipes containing a very high percentage of limestone. Rust is particularly difficult to remove. We recommend a stain remover that contains oxalic acid to clean these stains, making the entire surface shine again.

Ink Stains

Ink is one of the most dangerous stains in contact with the sink. If they are left for a long time, they ruin both the surface and the aesthetics but are not difficult to remove. The ink stain must be removed immediately by acting on it with a soaked cloth and a little alcohol. In this way, the stain disappears and the sink is as good as new.

Things not to do

There are things not to do to avoid deteriorating the surfaces, small precautions that save the sink from stubborn damage and extend its life. One of the things that can be avoided is to place pots that have just been removed from the hot stove or, in any case, higher than 280 degrees on the sink as they form permanent burn stains. Do not use acid products, alcohol, solvents or bleach directly on the surface as they will corrode or stain the sink. The use of an abrasive sponge is also forbidden because it will damage and damage the sink’s surface and finally, do not use ammonia or resulting aggressive products that especially stain the sink in fragrance.


We have seen how to clean the surfaces of fragrant sinks, how to clean light-colored sinks and what stains can form and above all, how to avoid damaging and deteriorating them through easy-to-apply steps. If you have applied these small precautions, then your built-in sink has a longer life than those who do not use a suitable and daily cleaning that goes to preserve the surface of the sink.
