Medium Density Fiberboard, better known as MDF, is a popular material used to make cabinets, including kitchen cabinets that often become dirty with grease, fingerprints and food splatters. MDF cabinets are typically covered with paint or a veneer such as vinyl and do not swell when wet like regular wood, making cleaning them a cinch. Pay careful attention and clean thoroughly around any handles since that is where much of the dirt and grime accumulates.
Wash MDF cabinets down with a soapy dish rag, much like you would use to clean your countertops.
Spray veneer or painted MDF cabinets with a heavy duty kitchen or all-purpose cleaner and wipe clean with a rag. Use a wet, clean rag to wipe them, rinsing the rag in clean warm water often.
Clean unfinished or unpainted MDF with a mild oil soap, designed to clean wood. Oil soap must be diluted with warm water, so read the label for dilution instructions. Then, rinse the cleaner off with a wet rag, rinsing the rag often.
