Care and maintenance

For a longer life. Lehni works with materials that are as durable as possible. You can further extend the life of your piece with the right care.


A special cleaner and a microfibre cloth are suitable for removing dirt from metals. Avoid using abrasive cleaners or metallic sponges since these may scratch the surface. Home remedies are also often effective on metals: Use a few drops of vinegar, the juice of a squeezed lemon or a paste made from baking soda and water (mix 3 tbsp. of baking soda with 1-2 tbsp. of water). Rub the mixture on the dirty stainless steel surface and rinse thoroughly with water.


The surface of veneered furniture is protected by a lacquer. Regularly wipe off dust with a soft, dry cloth or a supple, slightly damp piece of leather, moving in the direction of the wood fibres. You can also add a little bit of detergent to the water. Avoid bleaching agents and acidic additives and any other cleaning, polishing, or even scouring agents. Lacquered veneer surfaces must not be cleaned with microfibre cloths. Acidic liquids, e.g. fruit juices or alcohol, should be dabbed off immediately and the surface wiped with a damp cloth/leather.


Loose dirt can be removed with dust-binding cloths or vacuumed off. To remove adhering dirt, dissolve a pH-neutral cleaner in water according to the manufacturer's instructions. Then soak a soft cloth in the cleaning solution, wring out well, and wipe the linoleum surface.
Special instructions:

  • Especially in the post-oxidation phase, a "yellow tinge", the so-called drying chamber film, develops on linoleum. This is particularly noticeable on light colours and occurs when the flooring surface is covered for a longer period of time. As soon as the flooring is exposed to daylight again, the linoleum regains its original colour.
  • Use suitable saucers and flowerpots made of terracotta or clay to prevent discolouration.
  • If you need to disinfect the linoleum surface, only use a surface disinfectant suitable for linoleum (test on a sample or on a non-visible area beforehand).
  • Remove foods that may leave stains (e.g. ketchup, red wine, coffee, etc.) immediately.
  • The desktop material can only withstand heat up to 50°. Rule of thumb: If objects are hot to the touch, you should not place them on the material.
  • Use a shelled and skinned walnut to remove scratches by rubbing the white nut meat over the respective area and polishing with a soft cotton cloth.

Upholstery fabrics

Like all materials that are in daily use, upholstery fabrics also require regular care.
Generally, you should

  • vacuum regularly with a suitable upholstery nozzle or brush;
  • clean with a damp cloth every six months to maintain the elasticity of the fibres; wipe velour fabrics once in each direction of the fibre and allow to dry completely before use.


Vinegar and lemon are reliable cleaners and are gentle enough to be used on plastic. Simply wipe down the plastic object with lukewarm rinsing water and follow up with a mix of lukewarm water with vinegar or lemon.
