This manual contains basic rules to maintain the items made of acrylic solid surface GRANDEX. Following these rules in everyday operation will ensure durability and ideal appearance of the surfaces made of GRANDEX.

Operating tips for surfaces made of GRANDEX

  • It is not recommended to cook directly on the tabletop using knives and other sharp objects — meaning no chopping, cutting, or grinding. Protect the tabletop surface by using a chopping board.
  • Be aware to do not use sharp or scratching objects on the GRANDEX surfaces, to prevent scratches and scuff marks.
  • Please be aware that small scratches, dust and traces of natural wear on light surfaces with sand texture are less visible, than on dark surfaces with heavy shades or of a single color.
  • Avoid putting pots, pans, and kettles, which have just been removed from fire, and other warmed-up kitchenware into the kitchen sink or directly onto the tabletop. Do not forget using trivets or similar made of heat-insulation material, and put a protective pad into your kitchen sink.
  • First open the cold water tap if you need to pour boiling liquid into the sink, so that the boiling water for example mixes with cold water. This will help avoid the thermal shock, which may result in damaging the washbasin or kitchen sink.
  • Make sure that the bottom of large cooking utensils, extending beyond the cooktop, does not hang out over the tabletop surface and does not touch it.
  • Corrosive chemical substances (e.g., strong acidic liquids for cleaning sewer pipes, agents with methylene chloride for cleaning baking ovens and cookers, acetone and other similar substances) occasionally spilled onto the GRANDEX surface, shall be immediately washed off using soap solution and plenty of water. If you let chemicals sit for a longer time, they can damage the surface.
  • Fiercely boiling water is dangerous for the GRANDEX surfaces — it can leave microcracks and whitish stains.

Routine care for the GRANDEX surfaces. Recommendations

Acrylic solid surface GRANDEX has no voids and microcracks, meaning it is impervious for different impurities and moisture. This ensures that dirt, grease and other household impurities that stay on the surface, are as a rule easy to remove with a sponge and conventional mild detergents.

Nevertheless, it is recommended to immediately remove any impurities and spilled liquids, especially colored ones, from the surface using a flannel or other soft cloth.

Shall there be any stubborn stains of iodine, brilliant green, ink, bright juice of fruits and vegetables or similar, consult the Section “how to remove complex stains”.
