Here are some tips:
We want your nightstand to last as long as possible, so we recommend that you tighten screws within the first two weeks after assembly. For added safety, check the tightness of all screws every two months.
Avoid cleaning MDF (Medium-density fibreboard) material with water. When necessary, clean the surface with a slightly wet cloth and immediately dry thoroughly. For that hard to remove residue, use a small amount of mild soap. Do not use bleach.
Do not apply any wood treatment to the table top and drawer since these are made of MDF.
Wipe up spills as they happen with a damp cloth and wipe dry. Avoid scraping or rubbing the steel legs with an abrasive cloth that could damage or remove the powder-coating from the surface Do not use cleaning solutions, chemical solvents, strong detergents, cleaners with bleach, or furniture polish.
Look for a vinyl cleaner from your local hardware. Spray a light coat on the surface then wipe dry with a towel. You can use a sponge soaked in water as an alternative.
