Cleaning a Composite Sink: Here's How to Do It

Our composite sinks are primarily made from quartz, with acrylic resin as a binding agent, and require the right care and attention. With the correct cleaning and maintenance routine, your sink will stay looking beautiful for years to come.

Use the Right Products to Clean Your Composite Sink.

Composite sinks require proper cleaning and maintenance, so it's important to use the right methods and products. This will help keep your sink looking its best for longer.

As part of your daily routine, always dry the sink thoroughly with a soft cloth. This prevents water from remaining on the surface, making the sink easier to clean and maintain. It also helps prevent excessive limescale build-up and staining.

Cleaning Stubborn Stains.

Have stubborn stains developed in your composite sink? Our materials specialist recommends the following cleaning methods:

• Vinegar and water: The best way to tackle stubborn stains is with a mixture of vinegar and water. Mix them in a ratio of 1:40 and apply the solution to the surface of the sink. Leave it to work for 20 minutes, then rinse thoroughly with clean, cold water.

• Baking soda or household soda: For stubborn food residue, baking soda (also known as bicarbonate of soda) or household soda can help.

• Important: We strongly advise against using corrosive cleaners, citric acid, solvents, or bleach-based cleaners on your sink.

Removing Limescale.

If limescale does occur, you can easily remove it with a few helpful tips:

• White vinegar: Gently warm some white vinegar and apply it to the limescale. Alternatively, soak a cloth or sponge in lukewarm white vinegar and place it directly on the affected areas. Leave it to work for 20 minutes, then rinse thoroughly with clean water and dry the sink with a soft cloth.

• Specialist limescale remover: Use a specialist limescale remover suitable for composite surfaces.

• Avoid abrasive products: Do not use abrasive sponges or cleaning products, as these can damage the surface of your sink.

   

Daily Cleaning Tips.

• To prevent stubborn stains, clean your composite sink daily with a soft cloth. Avoid using abrasive sponges.

• We also recommend cleaning your sink daily with a mild soap.

• Always dry the sink thoroughly with a soft cloth to prevent water marks and limescale build-up.

Using and Maintaining Your Composite Sink.

For everyday use, we recommend following a few simple maintenance tips.

Use heat-resistant silicone mats to prevent hot pans from coming into direct contact with the sink. This helps prevent stains and discolouration caused by heat from hot pans or boiling-water taps.

It is also important to avoid dropping sharp objects into the sink, as they can damage the surface. Similarly, avoid cutting food directly in the sink to prevent scratches and other damage.
