Granite sink care and cleaning

The composition of granite composite sinks varies between manufacturers. This guide therefore offers general, cautious advice. Always follow the care instructions supplied with your sink if they differ. Test any new cleaning product on a small, inconspicuous area of the bowl first.

For everyday care, use warm water, a soft sponge and a little washing-up liquid. Rinsing the bowl after use prevents food residue and coloured liquids from drying onto the surface.

Dry the surface with a soft cloth after cleaning to reduce limescale build-up, especially in hard-water areas. Pale marks left by dried water droplets are more noticeable on dark sinks, making drying particularly useful for these colours.

Diluted vinegar or a citric acid solution is commonly used for limescale. Apply it with a soft cloth, leave it briefly, then rinse thoroughly and dry. Do not leave acidic solutions on the surface for extended periods.

If limescale builds up frequently, making this a weekly routine is easier than removing a thick layer later.

Tea, coffee, beetroot, pomegranate, tomato sauce and some spices can leave marks if left on the surface for a long time. These may be more noticeable on light-coloured sinks. Rinsing such substances away promptly is the simplest precaution.

For grease and stubborn dirt, a paste of baking powder and a little water is often sufficient. Apply with a soft sponge, then rinse thoroughly.

Steel wool, harsh scouring pads and abrasive powders can change the surface texture and sheen. Do not leave strong chemicals such as bleach on the surface in high concentrations or for long periods. Keep drain cleaner off the bowl surface; use it only in the drain and according to its instructions.

Unless the manufacturer specifies suitable heat resistance, do not place pots or pans straight from the hob directly into the sink; use a trivet. Running cold water while pouring away boiling water is a useful habit.

Do not pour used frying oil down the drain: it can solidify as it cools and block the trap. Emptying the strainer regularly and removing and cleaning the trap a few times a year helps prevent odours and slow drainage.

The overflow can accumulate dirt over time. Clean it occasionally with a small brush and warm soapy water.

A heavy or pointed object dropped into the sink can leave a mark or crack. If you notice a crack, avoid pouring hot water onto that area or placing heavy loads on it. Photograph the damage and contact us about your product’s warranty terms.

Repair kits may reduce the appearance of minor surface damage, but results depend on the colour, type of damage and application. Check your warranty coverage before attempting a repair, as unauthorised work may affect its terms.
