To ensure the longevity of untreated poplar wood clogs and prevent cracking, the wood should be treated regularly with a natural wood oil, such as linseed oil. Before application, the surface must be thoroughly cleaned and dried; if necessary, the wood can be lightly roughened with fine sandpaper to allow the oil to penetrate more easily. It is also important to protect the clogs from extreme temperature fluctuations and excessive humidity, as the wood is a natural material that expands and contracts and is prone to cracking if stored improperly or dried out.
