If the furniture becomes dull in colour over time or when the wood becomes dry, you can nourish the wood veneer with boiled linseed oil or another maintenance oil for furniture. You can find this product in any DIY store. Linseed oil nourishes and protects the veneer for a long time and also prevents moisture from penetrating. The oil is very easy to apply with a cloth and can be rubbed in lightly. The next day, the linseed oil has been completely absorbed and the veneer is dry and smooth again. In addition, it regains depth and its original wood colour.
