A majority of kitchen cabinets are finished with a washable surface. Wood cabinets will have a protective seal to protect the surface. Painted or laminated cabinets have very easy to care for surfaces.
Technique:
Wipe up spills as soon as they occur. Use a mild detergent solution for regular cleaning. Avoid abrasive cleaners and tools. Dry afterwards.
Specialized Tools & Chemicals:
Some manufacturers recommend waxing wood cabinets. Paste or liquid furniture polish when applied on a regular basis (every 6-12 months, depending on use and sunlight exposure) will help repel spills and stains and keep the wood protected.
