Disclosed herein is a method. The method includes applying a fluid to a perforated upper layer. The perforated upper layer forms an exposed surface of a multi-layer structure. The method also includes allowing the fluid to pass through the perforated upper layer and contact a contaminant within a core layer of the multi-layer structure. The core layer is disposed beneath the perforated upper layer, opposite the expose surface, and is coupled to the perforated upper layer. The method also includes applying ultrasonic energy to the exposed surface of the multi-layer structure using an ultrasonic generator to loosen the contaminant into the fluid. The method also includes removing the fluid with the loosened contaminant from the multi-layer structure.
