The surface of the wooden product is protected by a lacquer. Nevertheless, the colors of the wood may change over time. Natural maple may darken, while the pigmented surface of dark ash may become lighter due to UV radiation. The surfaces can be cleaned with a soft cotton cloth or, if necessary, with a damp leather cloth and, if applicable, a mild cleaning agent. Do not leave the products in water (not dishwasher safe). Do not use scouring cleaning agents or abrasive materials such as microfiber cloths, steel wool, sandpaper, or rough sponges, as these will damage the protective lacquer and cause scratches. Do not use acidic, alkaline, highly chlorinated, or bleach-containing cleaning agents. Dab off liquids and stains as soon as possible and do not allow them to dry. Do not place hot or abrasive objects on the wood. Wood care products, polishes, or oils are not necessary, as the surfaces are lacquered and the substances therefore do not penetrate the wood, but remain on the surface. Avoid strong temperature fluctuations, high humidity, and direct or prolonged sunlight.

Clean regularly with a soft cloth or sponge and a solution of neutral, mild detergent (pH 7) and water. Cleaners containing hydrochloric acid, formic acid, chlorine bleach, or acetic acid must not be used. Do not use abrasive cleaners, rough cleaning cloths, metal brushes, scouring pads, or microfiber cloths. Residues from personal care and cleaning products can cause damage—such as hair dye, perfume, aftershave, nail polish, toilet cleaner, or other harsh cleaning agents. Drying and polishing the surface prevents limescale buildup and staining. With regular cleaning and careful maintenance, the surfaces will retain their attractive appearance.
