Cleaning pad having preferred performance with representative cleaning solution
A cleaning pad for absorbing liquids from a hard, target surface. The cleaning pad has a hydrophobic floor sheet, and a core joined to the floor sheet. The core has absorbent gelling material therein with a gradient distribution, so that the pad has a particular minimum absorbency as used with water or with common amine oxide cleaning solution. A hydrophilic smoothing strip is joined to the outwardly facing surface of said floor sheet. The cleaning pad provides both good absorbency and a coefficient of friction falling within a specified range judged advantageous for cleaning. The absorbency and coefficient of friction work well with both water and an amine oxide cleaning solution.
