Most cabinets are factory manufactured and finished, and even wood cabinets have enough varnish or other protective coating so that you can use a cleaning solution. The oil slick that builds up on cabinets - especially around the handles - is a combination of kitchen grease, food smears, skin oil and hand lotion transferred to the cabinet. All-purpose cleaners aren't equal to the challenge.

If your cabinets are plastic laminate (formica or other plastic), metal, painted metal or glass, you can wash them all over with a strong alkaline cleaner, which is available at a janitorial supply store. Or use a heavy-duty cleaner from the supermarket. Mix according to directions and apply the solution with a sponge. Let it sit a minute or two, then take a white, nylon-backed sponge and scrub wherever necessary. Remove the grimy suds from the sponge by squeezing it into the sink or a slop bucket, never back into your cleaning solution. Then rinse with a damp cloth and wipe dry with a terry cleaning cloth to remove any last traces of scum and leave the cupboards clean and glowing.

Never use acids or powdered cleansers on cabinets. A good overall washing once a year should be enough. Keep a spray bottle of all-purpose cleaner handy the rest of the time and spot-clean after heavy kitchen use.

On wooden cabinets, take a gentler approach. To get off stubborn dirt, wash around all handles and any other grease zones first with hand dishwashing detergent. Then wash the entire cabinet, including the handle areas, with an oil soap solution. Just wipe lightly with the solution and buff dry immediately with a terry cleaning cloth. Always wipe dry with any grain or pattern. Seldom do you need to add any polish because the surface has its own sheen when clean. If your cabinets are dull from wear or age, spray furniture polish very lightly once a year or so to fill in the pores and bring back some life.
