When cleaning unfinished wood, in which direction should the cleaning be done?

Cleaning unfinished wood should always be done with the grain. This approach is important because wood is a natural material with fibers that run in a particular direction. When cleaning, moving with the grain helps to avoid damaging those fibers and minimizes the risk of scratching or creating visible swirls in the surface.

Using this method also allows for a more thorough cleaning, as it enables the cleaning solution or tool to penetrate the fibers more effectively. Cleaning against the grain or in circular motions can disrupt the wood's finish, leading to potential long-term damage, such as splintering or the raised grain. Therefore, adhering to the natural flow of the wood not only preserves its integrity but also enhances the overall appearance of the surface after cleaning.
