Dekton Care & Maintenance

Sink run in marble-effect Dekton Aura 22 showing a large prep area.

Due to its practically zero porosity, the ultra-compact Dekton surface is highly resistant to staining in day-to-day use and from chemical products, making it ideal for use as a kitchen worktop and as a surface for other kinds of work, both inside and out.

Dekton General cleaning

For best results in general cleaning, We recommend the use of Barkeeper’s Friend, a high performance surface cleaner available widely, to be applied with a sponge or scouring pad. 

If this product is not available, the best option is to use a neutral soap and water.

Cleaning stubborn stains on Dekton

In the case of aggressive stains, either from products that are resistant to normal cleaning agents or because they have remained on the work surface without being removed, we recommend using more specific products.

The accompanying table shows the various types of stains with their corresponding cleaning products:


  • Grease and oil: Alkaline detergent / solvent
  • Ink: Solvent
  • Rust: Acid
  • Limescale: Acid
  • Wine: Alkaline detergent / acid
  • Tyre rubber: Solvent
  • Ice cream: Alkaline detergent
  • Resin / nail varnish: Solvent 
  • Coffee: Alkaline detergent / acid 
  • Candle wax: Solvent 
  • Residual cement: Acid
  • Epoxy adhesive and grouting: Solvent
  • Cola: Oxidant
  • Fruit juices: Oxidant
  • Tar: Solvent
  • Nicotine: Solvent / oxidant

Quartz Care & Maintenance

Polished quartz countertops with custom drainage grooves

Quartz kitchen worktops (including Silestone) are very low-maintenance products that can be easily cleaned and kept their best day-to-day using soap and warm water. Regular cleaning will maintain their beauty for many, many years. 

For optimum results, we recommend using Barkeeper’s Friend cleaner once every few weeks to deep clean and return to perfect lustre, available in-store.

Water Repellents and Sealants on Quartz

Do not use water repellents or sealants to bring out the lustre. Once it has been installed, the sheen on quartz is the natural sheen/lustre of the product itself. Sealants and water repellents provide an artificial, ephemeral shine.

Do not use paint strippers, caustic soda, or products with a pH of more than 10. If bleach or solvent is used, it should be diluted with water and never left in permanent contact with the product.

Bleach and Solvent on Quartz Worktops

Bleach and solvent can continue to affect the product 12 hours later. Do not use chlorine-based products like dichloromethane (present in paint stripper) The surface of the material should not be re-polished – either on floors or on a worktop.

Do not use degreasing agents such as those used in oven cleaners. Keep quartz worktops separate from sources of heat (deep-fat fryers, etc.).

Temperature and Hot Pans on Quartz

Although quartz can withstand high temperatures for short periods of time, its performance varies with respect to different factors like thickness, colour, location, etc.

For this reason, it is not recommended that the product be exposed to sustained contact with a heat source, nor should hot saucepans, frying pans, deep-fat fryers, etc be placed directly on it. The use of a hot pad or trivet is recommended in such situations.

Chemicals on Quartz

  • Do not use under any circumstance: Hydrofluoric acid, Dichloromethane, NaOH – caustic soda, paint strippers
  • Bleach: Do not use for maintenance. When this product remains on the surface for more than 12 hours, it may lose its sheen.
  • Alkaline cleaning products with Ph>12: Do not use for maintenance: when this product remains on the surface for more than 12 hours, it may lose its sheen.

Marble and Granite Care & Maintenance

Regularly clean your natural stone surfaces with a damp cloth and dry-off worktops to avoid dull patches appearing where water and soap residues may have been left behind during use.

A light neutral detergent or soap may be safely used as well as household spray polishes such as Pledge or Mr. Sheen to maintain the surface shine after cleaning.

Acidic Products on Natural Stone

Natural Stone surfaces are treated before leaving the factory to help resist staining.

Some products however (such as wine, perfumes and fruit juices) can still cause staining and may even damage the surface if left on for too long, so care must be taken to remove spills of these products thoroughly with soap and water, then rinsing off immediately.

Oil-based Products on Natural Stone

Care should also be taken with oil based products so as not to allow them time to soak into your surfaces should they spill or drip onto them.

Wipe off with a cloth as soon as these products come into contact with your surfaces.

Stubborn and Dried Spills on Marble and Granite Surfaces

If needed, apply a non-abrasive household cleaner and rinse to remove residue. To remove stuck-on material such as food, gum, nail polish or paint, scrape away excess with a blade or putty knife and then use a damp cloth to remove any residue.

For extra-stubborn stains, a non-scratch pad, such as Scotch-Brite is recommended along with a non-abrasive cleaner. Drainer grooves can be cleaned using 000 grade, non-oiled wire wool but always avoid the use of abrasive cleaners or scouring pads.

Things To Avoid

Avoid the use of abrasives or strong detergent cleaners as these may damage your surfaces.

Avoid knocking or banging the edges and corners of your surfaces as chipping may occur. Avoid putting hot pans down directly onto granite surfaces as they may cause marks or damage. 

Avoid contact with strong acids, chemicals including paint stripper, brush cleaner, oven cleaner, nail varnish remover, degreasant or similar products. To avoid blunting of knives and staining on granite surfaces, use a chopping board rather than cutting fruit and veg directly on the surface.

Do not move your worktop from original place of installation

Porcelain Care and Maintenance

Porcelain Island with quartz perimeter worktops

For the ordinary cleaning of porcelain worktops, it is advisable to remove the dust with a dry and clean cloth. Afterwards, we recommend using Barkeeper’s Friend, Fila Brio or another neutral general household surface cleaner that is specified to be suitable for porcelain.

We suggest using the doses recommended by the manufacturer and a microfibre cloth.

In any case, to avoid extraordinary cleaning, it is advisable to immediately remove any stain before it dries. In the case of dirt that is resistant to ordinary cleaning, it is recommended to use a detergent specific to the type of dirt.

Prompt action remains an important factor for the success of the cleaning operation.

It is suggested to perform a preliminary test on a small stained portion, verifying the effectiveness of the detergent before using it on the whole surface.

Never use concentrated hydrochloric acid and/or caustic soda or detergents that contain hydrofluoric acid and/or its derivatives.

Below is a list showing detergents suitable for various types of dirt:

  • Grease and oil: Degreasing detergent
  • Ink: Degreasing detergent
  • Rust: Rust remover
  • Limescale: Descaling detergent
  • Wine: Degreasing detergent
  • Rubber: Degreasing detergent
  • Ice cream: Degreasing detergent
