An adjustable scrubbing implement for cleaning a surface is disclosed. A resilient base that comprises a center portion and a plurality of resilient fingers each is joined at a proximal end thereof to the center portion and extends radially away therefrom. The rigid cap comprises a side portion fixed at a top end thereof to an inside upper side of the cap, and terminates at a wider open lower end.
