Here are some tips:
We want your desk to last as long as possible, so we recommend that you tighten screws first 2 weeks after assembly and for an added safety check the tightness of all screw every 2 months.
You'll usually want to avoid cleaning MDF (Medium-density fibreboard) with water but those coffee spills do happen. When necessary clean MDF surface with a slightly wet cloth and immediately dry thoroughly. For that morning after hard to remove residue, use a bit of chemical-free (including bleach) mild soap.
To ensure that your desk will retain their durable surface for many moves to come, treat only the base (solid wood) of the desk with wood treatment oil when it starts to wear or become dry. Avoid the use of commercial waxes or polishes, glass cleaners or abrasive (fancy word for rough) cleaning materials, as they might damage the finish. *Do not treat the desk top, as the material is MDF and will not react well to any wood treatment.
