while the present invention is susceptible of embodiment in various forms , there is shown in the drawings and will hereinafter be described a presently preferred , albeit not limiting , embodiment with the understanding that the present disclosure is to be considered an exemplification of the present invention and is not intended to limit the invention to the specific embodiments illustrated . referring now to the figures , set forth is a cleaning implement 100 comprised of a holding member 102 and an abrasive pad 112 . in a primary embodiment the holding member consists of a fluid retaining sponge material having a cavity 104 formed along one surface . the sponge material is generally an open celled structure that can hold water and when moved over a surface is capable of removing grit , dirt , grime , mildew and other unwanted particles from the surface . the foam sponge is capable of holding liquids and typically has a density between 1 . 30 - 2 . 50 lbs / ft3 and constructed from random - celled hydrophilic urethane . the holding member 102 is defined by a top surface 105 and a bottom surface 106 , first 107 and second 108 side surfaces , and first 109 and second 110 end surfaces . illustrated is a holding member 102 having a length l of about 7 . 3 ″, a width w is about 4 . 25 ″ and a height h of about 2 . 5 ″. the sponge material is of a porosity capable of fluid retention . in a preferred embodiment , the abrasive pad 112 and said cavity 104 are of a substantially rectangular shape , whereby the cavity walls having first sidewall 114 and second sidewall 116 ; and first end wall 115 and second end wall 117 constructed and arranged to frictionally engage the abrasive pad 112 in any direction despite the force applied to the cleaning implement 100 . in this manner the height of the abrasive pad 112 can exceed the height of the side and endwalls . during a cleaning motion , the height of the abrasive pad 112 extends outward from the surface of the holding member to assure the abrasive pad 112 is the primary contact surface . this arrangement allows the individual &# 39 ; s hand to avoid contact with the abrasive pad which may consist of melamine . hand pressure is used applied to the holding element and the abrasive pad for deep cleaning of surfaces , the holding member maintaining a space between the hand and the abrasive pad . the bottom surface of the holding member 102 includes a cavity 104 having a base wall inset from the bottom side surface forming first 114 and second 116 sidewalls and first 115 and second 117 end walls , each having a uniform depth d of about 0 . 75 ″. the cavity 104 sidewalls 114 , 116 and endwalls 115 , 117 form a continuous inner wall having a uniform depth extending into the holding member . the cavity is constructed and arranged to cooperate with an abrasive pad 112 to frictionally engage on all sides . the cavity 104 is of a substantially conjugate shape . the abrasive pad 112 can be defined by a wear surface 120 and an attachment surface 121 with outer sidewalls 124 , 125 and outer endwalls 122 , 123 forming a thickness . the thickness is greater than the height of the cavity wall 0 . 75 inches and preferably about one inch in thickness . the abrasive pad 112 is positioned within the cavity 104 presenting a wear surface that extends outward from the top surface 105 of said holding member . the abrasive pad 112 is removable for ease of cleaning the holding member or for purposes of replacement when the wearable material degrades the performance of the cleaning apparatus . cavity 104 sidewalls and endwalls hold the abrasive pad 112 in position . should the abrasive pad be drawn over a surface imperfection that would otherwise grab the abrasive pad , the cavity sidewalls and endwalls hold the abrasive pad in position . should the surface imperfection damage the abrasive pad 112 , the pad can be easily replaced thereby saving the holding element 102 ( sponge ) from becoming waste . further , a sponge 102 is cleaned by soaking in water and squeezing out the water to expel contaminants . by use of a removable abrasive pad 112 , the sponge 102 can be cleaned properly as the abrasive pad will not hamper the cleaning motion . for instance when a nonporous abrasive pad is inserted , such as melamine , the sponge can entrap fluid behind the nonporous abrasive pad for melamine lacks the ability to pass fluids through its cell structure . the abrasive pad 112 is releasably attached to the holding member 102 by frictional engagement with the sidewalls , or can be supplemented by use of a fastener 142 attached to the base wall of the cavity 104 . the sidewalls and endwalls of the cavity 104 entrap the abrasive pad 112 within the holding member 102 allowing an individual to clean an area using lateral movement in multiple directions . for example , the holding member 102 is made of a fluid retention material namely open cell foam or sponge material , an individual can soak the sponge before cleaning an area . the wet sponge 102 facilitates the abrasive pad by providing lubrication to prevent dirt and grit from marring a surface while the cavity 104 maintains the abrasive pad 112 in position . in a preferred embodiment the abrasive pad 112 is made of a material designed to wear as it is used to scrub an article . in this manner the material being abraded by the frictional contact between the abrasive pad 112 and the surface of the article wherein the sponge operates to pick up dirt , grit and residuals from the wear material . one example of such an abrasive pad 112 that provides a wear material is melamine based foam . typically melamine based foam is used as an independent abrasive pad 112 or is permanently attached to another material . for purposes of this application where the abrasive pad is used in combination with the fluid holding member , the preferred melamine abrasive pad has a density of about 1 kg / m 3 to 11 kg / m 3 . the melamine member being an open foam - like material consisting of a formaldehyde - melamine - sodium bisulfate copolymer . the foam is micro - porous with a polymeric substance so that it operates as an extremely fine abrasive material that wears away , like a pencil eraser . the melamine member being abraded as the melamine member scrubs a surface . while not limiting , it has been discovered that using a melamine based foam with a density in this range provides a significant advantage in that it provides better wear resistance of the material , durability , and improved scrubbing ability , without the material becoming too hard so that it cleans well while remaining flexible and absorbent in a wet environment . by use of an abrasive pad 112 having a depth larger than the sidewalls of the cavity 104 , the consumer can visually determine when the abrasive pad should be replaced so as to lessen damage to the holding member . conventional melamine foam used for cleaning purposes is made from a melamine resin which can be a skin irritant . in addition , the cleaning implement can include a fastener , such as hook 142 and loop 140 , alternatively , fastening can be accomplished by snap , elastic band , button , peel and stick or the like releasable attendant fastener , positioned between said cavity 104 base wall and the mounting surface of the abrasive pad 112 , wherein the abrasive pad is primarily held within the cavity by the sidewalls and endwalls of the cavity and the base wall . this assists in holding an abrasive pad used in commercial environments where deep cleaning a surface with known imperfections or in very wet environment wherein the holding member may lose its shape . for instance , the cleaning of uneven grout between tiles or grates can attempt to draw an unfastened abrasive pad 112 from the cavity 104 . in an alternative embodiment , the holding member 200 consists of a non - fluid retaining member 202 , such as a double - open celled structure capable of holding liquids , having a top surface 205 and a bottom surface 206 with end surfaces 207 and 209 , and side surfaces 208 and 211 . the non - fluid retaining member 202 is laminated to a fluid retaining member 203 , namely conventional sponge foam , having a top surface 220 and a bottom surface 222 with side surfaces 223 and 224 ; and end surfaces 225 and 226 . non - reticulate extra firm scrubber being very porous , low density solid foam , open or closed cell structure , with few if any intact cells windows and it constructed of polyurethane or non - woven polyester , comprising a density of 1 . 8 +/− 10 % lbs / ft 3 . the non - fluid retaining member 202 and the fluid retaining member 203 have a substantially conjugate shape and are superposed upon each other and fixedly attached by adhesive or heat / pressure weldment . the fluid holding member is a double - open celled structure capable of holding liquids with a density between 1 . 30 - 2 . 50 lbs / ft3 and constructed from random - celled hydrophilic urethane . in this embodiment the non - fluid holding member 202 has a centrally disposed cavity 230 . the cavity 230

cavity 230 is constructed and arranged to cooperate with an abrasive pad 212 to frictionally engage the abrasive pad on the side walls , end walls and base wall . the cavity 230 is of a substantially conjugate shape as the abrasive pad 212 . the abrasive pad 212 having a top surface 214 and a bottom surface 216 with side surfaces 217 and 219 and end surfaces 218 and 221 . the abrasive pad 212 is positioned to extend at a predetermined distance above the top surface 205 of the non - fluid retaining member 202 thus being greater than about 0 . 75 inches in height and preferably about 1 inch in height . the abrasive pad 212 must be removable for cleaning or replacement . in this manner the holding member can be used for a variety of cleaning jobs by simply replacing the abrasive pad 212 with an abrasive pad of higher or lower abrasive material . further , should the cleaning implement be used in a particularly dirty environment , cleaning fish blood off a boat for example , removal of the abrasive pad would be necessary to rinse any material trapped behind the abrasive pad before reuse . the side walls of the holding member may include a grip edge 235 which is ornamental in design . in addition , the cleaning implement can include a fastener , such as hook 242 and loop 240 , alternatively , fastening can be accomplished by snap , elastic band , button , peel and stick or the like
