Which Cleaning Products Should You Use for a Black Resin Sink?

A resin sink is made from a mixture of composite materials, usually a combination of synthetic resin (polyester resin), long glass fibres and mineral fillers such as quartz, silicate, glass, sand, or granite. This mixture gives the sink some very useful properties:

• Impact and Scratch Resistance: Thanks to the hardness of the minerals incorporated during manufacture, a resin sink is highly durable over time

• Hygienic Material: Thanks to the resin’s smooth, non-porous surface, water runs off the sides of the sink, which helps to limit the growth of bacteria

• Easy to Maintain: The composite material used to manufacture a resin sink creates a non-porous surface, which limits the absorption of liquids and the appearance of stains

Using cleaning products suitable for a black resin sink is crucial for maintaining its appearance and extending its lifespan. In particular, this helps to:

• Preserve Its Colour: Unlike abrasive products or those containing bleaching agents, natural products do not alter the sink’s black colour

• Prevent Surface Damage: Some harsh cleaning products can cause micro-scratches. These micro-scratches encourage the appearance of stains and the growth of bacteria

• Maintaining the Shine: Inappropriate products can dull the finish, whether it is matt or polished

For a black resin sink, natural cleaning products – whether ready-to-use or made from scratch – offer the following benefits:

• Guaranteed Gentleness: They clean without damaging the surface, thus preventing micro-scratches and dulling

• Colour Protection: Free from bleaching agents, they preserve the depth of the black colour and prevent whitish marks

• Targeted Effectiveness: White vinegar, black soap, or bicarbonate of soda gently remove stains, limescale and greasy residues

• Fewer Deposits: Simple formulas, free from silicones and film-forming agents, which leave surfaces clean and residue-free

• An Eco-Friendly Choice: Using natural products helps to reduce water pollution whilst protecting surfaces

Removing Limescale, White Marks and Stains

With White Vinegar: Mix 25cl of white vinegar with 25cl of lukewarm water. Soak a cloth in this solution and scrub the areas affected by white marks. Rinse thoroughly and dry with a soft cloth. Additionally, white vinegar eliminates any unpleasant odours that may be coming from your sink!

With Bicarbonate of Soda: To remove stubborn stains, sprinkle bicarbonate of soda onto the sink whilst it is still damp and leave it to work for a few minutes. Then, scrub gently with a non-abrasive sponge. Rinse and dry.

Restoring the Shine

With Olive Oil: Wash the sink with lukewarm water and a mild soap to remove surface dirt. Soak a soft cloth in olive oil and gently rub the surface of the sink using circular movements. Leave for about 10 minutes to allow the oil to soak in. Wipe off any excess oil with a clean, dry cloth. This method is based on the use of a 100% natural cleaning product for black resin sinks. It helps to restore the black colour and gives the sink a shiny finish.

Caring for a Matte Black Resin Sink

To clean a sink with a matte finish: dilute a capful of black soap in half a litre of lukewarm water and clean the sink with a soft sponge. Rinse and dry the sink to prevent white marks from appearing. Avoid polishing products: these can alter the matte finish of your sink. Always opt for natural cleaning products when cleaning a black resin sink.

Caring for a Polished Resin Sink

To clean a sink with a polished finish: mix 25cl of white vinegar with 50cl of water and clean the bowl with a soft cloth or a non-abrasive sponge. After applying the mixture, rinse and dry with a microfibre cloth to prevent streaks from appearing. The vinegar and water mixture removes stains without affecting the sink’s shine in any way. You can also use a natural polish suitable for resin surfaces to maintain its shine. Make sure you apply the product in accordance with the manufacturer’s instructions.

To protect your black resin sink and prevent it from becoming damaged prematurely, avoid using abrasive sponges as these may scratch the surface and dull the finish. Do not use products containing chlorine or ammonia: these substances can permanently discolour the resin. Always rinse after cleaning, even when using natural products. Dry your sink after each use. Avoid thermal shock: do not pour boiling water directly into the sink, as this could weaken the resin and cause cracks.

If your black resin sink is looking dull, apply a small amount of linseed oil using a soft cloth. Leave it to work for a few minutes, then wipe it off with a clean, dry cloth. For an even longer-lasting effect, you can also use a natural protective wax, such as beeswax.
