To ensure the longevity of the sealed linden wood trough, it should be cleaned regularly with a soft cloth, lukewarm water, and mild soap. It is important to avoid harsh chemical cleaners, abrasive cleaners, and pressure washers to prevent damage to the protective sealant. After cleaning, the wood should be thoroughly dried to prevent waterlogging. Furthermore, it is advisable to protect the trough from prolonged, concentrated pressure and extreme weather conditions to prevent warping or cracking of the natural material.
