Abstract

The present invention provides a cleaning sheet for cleaning a surface which includes an additive applied on at least one of the outer surfaces of the sheet. The additive can have a penetration value at 25° C. between 20 dmm and about 100 dmm. The additive can have a “relative tack” between 55% and 94%. The additive can be applied at a level between 0.1 g/m² and about 2.3 g/m². The cleaning sheet leaves low levels of residue on the surface which is cleaned with the sheet.
