My whole apartment (5 rooms) is all paneling, so every spring I like to wash it with Murphy's Oil soap. I use to get my clothing and hands caught on the nails that hold all my pictures, so this year I went to the dollar store and bought a sponge mop that has a wringer that doesn't get your hands wet. This with a bucket of warm water with Murphy's worked great.
The regular pad for the Swiffer dry floor mop is perfect for wiping down walls and ceilings, that are easily reached with the extendable handle. This is a page about using a Swiffer to clean walls and ceilings.
