Details are given below of how to remove specific stains from your Silestone worktop. The precautions to take to keep your Silestone worktop in perfect condition can also be consulted, along with details of its resistance to chemicals.
Advanced Cleaning and Precautions
Grease stains and routine cleaning.
For grease stains apply a small amount of 409, Windex, or a common house-hold cleaner to the stain and rub with a scouring pad (e.g. Scotch-Brite) until it disappears. Rinse immediately with water.
Limescale stains (marks left by glasses, etc).
Sprinkle hydrochloric acid on the countertop surface and leave to work for one minute. Rinse with water. Follow the recommendations for use given by the hydrochloric acid manufacturer. Do not use on any products (taps, sink, etc) other than the countertop itself since it might damage their finish.
Use a knife and a drop of solvent (without any dichloromethane, methylene dichloride, dichloramine in its composition). Rinse with water.
For difficult stains, sprinkle 409, Windex, or a common house-hold cleaner on the affected area of the Silestone product for 2 minutes and then rub vigorously with a scouring pad (like Scotch-Brite). Then rinse generously with water.
Loss of sheen.
Loss of sheen on the surface of the Silestone countertop may be due to the use of products (waxes, sprays, sealants, etc.) to try to bring out its lustre, although these products lose their effect over time. This lack of sheen therefore has nothing to do with the original mechanical sheen of the product when it leaves the factory. To recover this non-natural sheen, a multi-purpose furniture spray that is suitable for the countertop can be used.
Do not place Silestone outdoors or in places with UV lighting.
• Over the years the colour and shade of Silestone products may suffer from the effect of the sun's rays.
Do not use water repellents or sealants to bring out the lustre.
• Once it has been installed, the sheen on Silestone is the natural 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 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 countertop.
• Do not use degreasing agents such as those used in oven cleaners.
• Keep Silestone separate from sources of heat (deep-fat fryers, etc.).
Although Silestone can withstand high temperatures for short periods of time, its performance varies with respect to different factors like thickness, color, 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 on it. The use of a hot pad or trivet is recommended in such situations.
We always recommend placing hot objects on top of hot pads.
Resistance to Chemicals
High resistance: Acis, Oils, Coffee, Wine, Soft Drinks, etc.
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.
Trichloroethylene: This may be used to remove a specific stain. After scrubbing, wipe off the product with clean water.
Acetone: This may be used to remove a specific stain. After scrubbing, wipe off the product with clean water.
Paint thinners: This may be used to remove a specific stain. After scrubbing, wipe off the product with clean water.
