These cloths are made out of thick cotton chenille fabric, and are just as good as the dry disposable mopping pads for dry dusting, but they really SHINE as a damp mop pad. Simply dampen the cloth with floor cleaner or soapy water or whatever you like to use, attach to your mop and go to town. Or, you can spray your cleaner right onto the floor and use the cloth to mop it dry. This listing is for a set of three cloths made to fit a standard swiffer or other similar convenience mopping system (the kind where you shove a corner of the cloth down into the hole to make it stay attached). Wash separately before use. Approximate size of pad is 12″ by 9″ (allows for about 1/2″ shrinkage). Fits mop head size 11″ by 5″.
