Light to medium soil conditions are most appropriate for the use of microfibers. Microfibers, due to their construction, have been shown to remove even microorganisms from smooth surfaces. Because of their ability to hold soil so well, they will work well wet or dry in almost all cleaning conditions.
I would not recommend them for extremely soiled areas or heavy grease buildup. Disposable clothes would be more cost effective and work better. If grease and oils are present, use with a degreaser than with just a water.
