A cleaning system is provided comprising a sealable container housing a saturated stack of durable fine spunbond fiber cleaning sheets; the cleaning sheets have an average fiber diameter less than 18 micrometers, a tensile strength of at least 140-g/g/m.sup.2 and a basis weight between about 15 g/m.

A cleaning system is provided comprising a sealable container housing a saturated stack of durable fine spunbond fiber cleaning sheets; the cleaning sheets have an average fiber diameter less than 18 micrometers, a tensile strength of at least 140-g/g/m.sup.2 and a basis weight between about 15 g/m.sup.2 and 85 g/m.sup.2. The cleaning sheets can be provided in stacked form and maintained within a sealed container wherein liquid is retained within the individual sheets as well as throughout the stack over time. The sheets can subsequently be removed from the container and applied to a surface wherein a high percent of the liquid is released from the sheet onto the surface in the initial pass and thereby allowing for improved treatment and/or cleaning of the surface.
