  • Publication number: 20100162508
    Abstract: The invention refers to a flexible and permeable cleaning article, more specifically the invention relates to a foam having a mechanical fastener for attaching scouring webs composed of hook-like projections, wherein said webs can be replaced depending on the type of cleaning needed, for example, heavy duty cleaning, delicate cleaning, surface polishing, etc. Flexibility and permeability are two important characteristics exhibited by the object of the present invention; said flexible article easily conforms to substrates and their particularities, such as corners and grooves, thus rendering the cleaning process easier and more efficient. Permeability allows water and chemical cleaning compositions (e.g., detergents, soaps, etc.) to pass through it, thereby forming suds.
