i use washclothes for my swifter. I keep one soaking in bleach/soap water, and one I use. About halfway through the kitchen floor, I switch them out. I just throw them in with the next load of whites.
For my hardwood floors, I keep my washclothes soaking in a pine oil solution inbetween uses. When they get dirty, they get washed with dirty overalls or rags (here on the farm, I wash rags about every 3-4 weeks)
