7. Maintenance
The following maintenance tips are provided as a guide. For non-specific surfaces, we recommend using a damp cloth. We advise you to use environmentally friendly cleaning products and to maintain your furniture regularly. Before using a cleaning product for the first time, test it on a small area that is not visible.

Fabrics: The coating fabrics require for maintenance only to regularly vacuum dust and lint using the corresponding tip of the vacuum cleaner. Removal of stains: In most cases, an absorbent, lint-free sponge will clean fresh stains immediately. To remove dry, encrusted stains, gently brush the fabric with a soft brush. Depending on the nature of the task, the use of a solvent may be necessary. In such cases, we advise you to seek professional advice. Never vigorously rub the surface of coating fabrics. Do not use a cleaning product containing a solvent if you do not have the necessary technical knowledge. If you leave your seat in the sun for an extended period of time, its color may change. We therefore advise you not to expose your seat to excessive sunlight.
Leather: Do not expose leather furniture to direct sunlight and keep it at a reasonable distance from any heat source, so that the leather does not dry out or harden. Immediately absorb the liquid stains with a cloth, and rinse with a little water if necessary. Never use aggressive products such as stain removers, turpentine, waxing, etc.
Metal: Spot Removal: To quickly remove stains on shiny, matt, chrome or aluminum surfaces, you can use a regular window cleaner on a clean soft cloth, then dry the surface with another soft cloth. Always gently clean metal surfaces, and do not rub to avoid scratching. Never use cleaners containing granular substances, acetic acid or citric acid.
Wood: Wood is a durable material, especially when its qualities are well used. Wooden furniture reacts to its surroundings: for example, it changes color under the influence of light. They also have the ability to adapt their own humidity to that of their environment. On the other hand, they crack and deform in case of significant temperature and humidity variations. For example, to avoid staining, immediately absorb any liquid coming into contact with the wood. Also, to clean solid wood surfaces and veneers, a simple soft cloth slightly moistened is enough. In case of more stubborn tasks, you can also use a product such as dish liquid. Never use powerful cleaners or cleaning products containing silicone or an abrasive substance. When cleaning, avoid rubbing as much as possible.
