Over time, the fats from the food you cook settle on the face of your cabinets. This grease buildup is often difficult to remove. Work through the process beginning with the steps least likely to cause damage to the finish.
Clean with baking soda
Baking soda is a basic compound that is effective at cutting grease. Additionally, it's not likely to cause damage to the underlying finish. Mix a small amount in water, and apply it with a sponge. Wipe away as much grease as possible without scrubbing too hard. Rinse the cabinet, and dry with a towel to prevent damage to the wood.
Boost the power with cooking oil
Clean cooking oil, mixed with a little baking soda, helps to dissolve the grease. Oil serves as a solvent for the grease without damaging the polyurethane finish like stronger solvents might. Use a mild dishwashing solution to wash away the oil and baking soda. Rinse the surface and dry it.
Try oil soap
Oil soap is safe for all types of wood. A powerful, grease-cutting agent, it doesn't damage wood. Follow the manufacturer's directions.
Condition the wood
A lemon-oil conditioner restores the oils your cabinets lose over time. Apply a light coat, and allow it to dry after cleaning. It makes it easier to remove grease the next time.
