What is best to clean and brighten kitchen cabinets.

Cabinet magic if they are wood

If they are wood and not painted try Scotts Liquid Gold in either spray can or bottle. Rub with soft white cotton cloth (like old tshirt)

Wash them with Murphy's oil soap, let dry, then buff with clean cotton rag

What were they washed with? if it was TSP, you probably damaged the finish. I use Dollar Tree Awesome Orange and Awesome Degreaser to clean my clients cupboards. Wear gloves. To get a shine back on, get some wipe-on satin poly. Make sure their clean first.

Try giving the cabinets a good brisk rub-down with a microfiber cloth. Mine seem to get a "haze" on the finish and it just needs to be buffed off to have a shiny finish again. Mine are a wood finish but this would work on a painted surface also.

Murphys oil products are wonderful for cabinets. Depending on what they are made of, you can try a few drops of lemon essential oil in water and wipe them.
