What is the correct process for applying oil on wood?

The process of applying oil on wood involves running the oil into the wood using a cloth, which ensures that the oil penetrates effectively into the wood fibers. This method allows for a controlled application, promoting even distribution and preventing excess oil from sitting on the surface, which can lead to a sticky or uneven finish.

Using a cloth not only helps in spreading the oil uniformly but also aids in wiping away any surplus oil that has not absorbed into the wood, ensuring a clean, optimal finish. The tactile feedback from the cloth also allows the user to gauge how much oil is being applied and if it is adequately soaking into the surface.

In relation to the other options, applying generously and leaving the wood uncleaned can cause problems such as an uneven finish and potential for the oil to never fully cure or dry, leading to a sticky surface. Rubbing oil into the wood with sandpaper is generally not recommended, as sandpaper can create scratches and debris on the surface, which may negatively impact the final look and feel of the wood. Lastly, applying oil before sanding can prevent the wood surface from being smooth, as the oil can clog the sandpaper and impede the sanding process.
