Dust all exposed surfaces of the furniture with a feather duster or soft dust cloth. Remove the cushions, if possible, and vacuum the exposed area. Use a crevice tool to get between non-removable cushions and in areas difficult to clean with the duster.
Pour a few inches of warm water in a bucket and add a squirt of mild dish soap, swishing it around with your hand. Dip a soft white cloth into the liquid, wringing out most of the water, and wipe down the faux leather for a basic cleaning. Wipe it down again with a damp cloth, then dry it off immediately with another soft white cloth. Using white cloths ensures no dyes transfer onto the pleather.
Dip a toothbrush into the soapy water solution to treat areas that are extra dirty, such as an area where sticky food or drink spilled. Wipe the area afterwards with a damp white cloth, then dry the faux leather.
Remove stubborn buildup with a vinyl upholstery cleaner, available from an automotive or furniture store. Pour some of the cleaner onto a soft white cloth or directly onto the problem area, as directed on the package instructions. Rub the solution over the affected area with the soft white cloth; then follow up with a damp white cloth. Dry with another white cloth.
