    Concrete

    Concrete hardens over a long period of time, becoming stronger and more resilient over the years. Porous materials like concrete are prone to marks. When you get your concrete product home, it will have been treated but it is important to maintain the concrete to give it a stronger and more resilient surface. Remember to be extra careful with a concrete table top for the first six months as this is when it is most sensitive. Avoid placing porous containers, plant pot saucers etc straight onto the concrete as they can release moisture and generate surface marks and discolouration. We recommend placing felt pads under things placed on top of concrete and moving them from time to time.

    General advice for concrete

    » Only use a cloth and warm water for cleaning. Avoid cleaning products. However, it is OK to use neutral and uncoloured soap.
    » Concrete table tops can be maintained with concrete wax. Once or twice a year is recommended.
    » Natural materials like concrete are often sensitive to marks. Marks usually occur when some type of liquid is left on the concrete surface for a long time. Acid is the worst enemy of a concrete table top – lemon, vinegar and fruit acids will make the table top “weather” and disintegrate unless they are removed immediately.
    » If there is a spill, use a polishing cloth (microfibre cloth) and work into the mark in circles. If you rub the same spot hard with the microfibre cloth, it can cause fine scratches. These usually disappear if you gently polish the area and add a new coat of wax.

    Limestone

    The limestone we use is quarried in Jämtland in northern Sweden, in a place called Grytan outside Brunflo. It formed more than 400 million years ago and is one of the oldest and hardest limestones in Europe. Limestone is a very pure mineral.

    General advice for limestone

    » Only use a slightly damp cloth (warm water) for everyday cleaning.
    » Constant use of neutral, uncoloured natural soap (available to buy in our shops) with a pH of more than 7, will soak into the limestone making it more attractive and more hardwearing too.
    » Polished limestone surfaces have limited absorption capacity so you only need to use a small amount of soap. A surface oversaturated with soap will become blotchy and matt. If this happens, clean it with water and a neutral cleaning product with a pH above 7.
    » Marks must be removed quickly to prevent them from spreading in the stone material. If the stain penetrates deep down, it can be very difficult or impossible to remove. Try to absorb the mark with kitchen towel or absorbent material (like bentonite clay or potato flour). Work it in with a damp cloth and water. Then use a solution of water and a neutral cleaning product with a pH above 7.
    » Limestone may crack if exposed to sudden, local heat. Never place a hot pan or casserole straight onto a limestone surface.

    Note! Acids can cause corrosive damage to limestone. Examples of acids are: cleaning products with a pH below 7, limescale removers, carbon dioxide, lemon, wine, vinegar, fruit juice, etc. Limestone cannot withstand salt either.
