Thebarbs 38 preferably comprise a resiliently deformable material such as, for example but not limited to, silicone and can comprise the same material as the remainder of the tether 16A as discussed above. It is noted that thebarbs 38 can additionally or alternatively be located on thesecond retainer 24 if desired. It is also noted that the barbs can alternatively have any other suitable configuration. -
FIGS. 13 to 19 illustrate the exemplarysponge cleaning device 12 according to the present invention for use in thecleaning system 10. It is noted that thesponge cleaning device 12 can alternatively have any other suitable configuration. The illustratedsponge cleaning device 12 includes a body ofmelamine foam sponge 40 having afront side 42 and arear side 44 opposed to thefront side 42, and aholding layer 46 secured to therear side 44 of the body ofmelamine foam sponge 40 to prevent relative movement therebetween. - The body of
melamine foam sponge 40 is sized and shaped for hand-held cleaning or scrubbing. The illustrated body ofmelamine foam sponge 40 is generally disk or cylindrical shaped having the opposite-facing and spaced-apart front and rear sides or faces 42, 44 connected by a substantiallyperpendicular sidewall 48 that extends between the front andrear sides rear sides sidewall 48. Thus, thebody 40 has a circular-shaped cross-section throughout its thickness. The body ofmelamine foam sponge 40 preferably has a diameter of about 1.5 inches to about 3.0 inches, and more preferably a diameter of about 2.25 inches. The body ofmelamine foam sponge 40 preferably has a thickness of about 0.4 inches to about 0.8 inches, and more preferably a thickness of about 0.6 inches. It is noted that the body ofmelamine foam sponge 40 can alternatively have any other suitable shape and/or size. - The front and rear sides or faces 42, 44 of the body of
melamine foam sponge 40 are each generally flat or planar. The front side or face 42 of the body ofmelamine foam sponge 40 is provided with a plurality of spaced-apartprotrusions 50 that extend outward in the forward direction. The illustratedprotrusions 50 are generally dome or semicircular shaped but any other suitable shape can alternatively be utilized. - The body of
melamine foam sponge 40 is a foam-like material comprising a formaldehyde-melamine-sodium bisulfite copolymer. The melamine foam sponge is preferably an abradable melamine foam which disintegrates or wears away during use. Suitable melamine foam is marketed as basotect and is available from BASF of Germany but any other suitable melamine foam can be utilized. Melamine foam is an open cell foam that is microporous and extremely hard so that when rubbed on a surface for cleaning it works like extremely fine sandpaper. The foam material is abradable and wears away or disintegrates to leave a residue on the surface that must be removed. When moistened with a liquid, rubbing the foam on a surface can remove otherwise “unremovable” external markings. It is noted that when the surface being cleaned is not of suitable hardness, the surface may be finely scratched by the melamine foam. - The illustrated
holding layer 46 is a relatively thin layer of material which covers and is secured to only the rear side or face 42 of the body ofmelamine foam sponge 40. The illustratedholding layer 46 is circular in shape to closely match the size and shape of the rear side or face 42 of the body ofmelamine foam sponge 40. The holdinglayer 46 preferably comprises a material such as, for example but not limited to, a scouring pad of metal or plastic mesh or the like which can be used to scour a surface. The scouring pad both makes it easier to grasp hold the body ofmelamine foam sponge 40 with a hand as it wears away by providing a non-wearable and relative slip-resistant resistant surface and assists in holding the body ofmelamine foam sponge 40 together against crumbling or breaking-apart during use to extend its useful life by providing a tear-resistant surface. The illustratedholding layer 46 has a thickness about the same as the thickness of the body ofmelamine foam sponge 40. Alternatively the holdinglayer 46 can be cloth. The cloth is preferably is natural or synthetic chamois which can also be utilized to buff and/or polish the marked surface after cleaning but can alternatively be any other suitable cloth such as, for example but not limited to, a micro-fiber cloth. When the holdinglayer 46 comprises cloth, it has a thickness much smaller than the thickness of the body ofmelamine foam sponge 40 and preferably has a thickness of about 0.05 inches to about 0.15 inches and more preferably about 0.10 inches. It is noted that the holdinglayer 46 can alternatively have any other suitable material, size, and shape. - The illustrated
holding layer 46 is secured to therear face 42 of the body ofmelamine foam sponge 40 to prevent relative movement therebetween. The illustratedholding layer 46 is secured to the body ofmelamine foam sponge 40 with a layer of adhesive or glue. The adhesive or glue is preferably a non-water soluble adhesive or glue. Any suitable adhesive or glue can be utilized. It is noted that the holdinglayer 46 can alternatively be secured to the body of melamine foam sponge i40 n any other suitable manner. - The illustrated
opening 14 extends entirely though thesponge cleaning device 12 from thefront face 42 to therear face 40 and extending through both the body ofmelamine foam sponge 40 and theholding layer 46. Theopening 14 is sized and shaped for free passage of the elongate holdingportion 20 of thetether 16 therethrough. Theopening 14 also is sized and shaped so that the first andsecond retainers opening 14 to retain thesponge cleaning device 12 on the hangingportion 20 unless enough force is applied to thesponge cleaning device 12 so that the first orsecond retainer opening 14. The required force to resiliently deform the first orsecond retainer sponge cleaning devices 12 hanging on the holdingportion 20 of thetether 16. The illustratedopening 14 has a rectangular shape with its length being substantially greater than its width. The illustrated length is about four times larger than the width. The length is also substantially larger than both the diameter of thetether hanging portion 20 and the diameter of the first and second retainers ornubs tether hanging portion 20 but smaller than the diameter of the first and second retainers ornubs - The illustrated
opening 14 is located in a position offset from the center of thesponge cleaning device 12 in a direction perpendicular to its length to a location about half way between the center and the outer edge of the sponge cleaning device 12 (best seen inFIGS. 10 and 11 ). It is noted that theopening 14 can alternatively have any other suitable location. - The
cleaning system 10 described above can be advantageously utilized to clean marks from a wide variety of items such as, for example but not limited to, golf clubs and the like. Because heads of golf clubs are used to strike golf balls lying on the ground, they tend to be easily inadvertently dirty and/or marked-up during use. The tether 16 (holding a plurality of the sponge cleaning devices 12) can be easily attached to a golf club bag using a carabiner clip or the like connecting the attachment passage oftether body portion 18 to the golf bag. - In order to remove this dirt and/or surface marks, the user grasps the
sponge cleaning device 12 secured in theuse position 26 of thetether 16 and rubs thefront face 42 and/orsidewall 48 and/or holdinglayer 46 of thesponge cleaning device 12 onto a surface of the golf club having any dirt or surface marks that are desired to be removed until the dirt or surface marks are removed from the club. Thesponge cleaning device 12 is then released so that it again hangs from the golf bag via thetether 16. This process can be repeated whenever there is undesired or surface marks on the golf club. When the sponge cleaning device i12 n theuse position 26 of thetether 16 is no longer usable, the user grasps thesponge cleaning device 12 and pulls with enough force so that thefirst retainer 22 resiliently deforms and the usedsponge cleaning device 12 passes over thefirst retainer 22 and off of thetether 16. With the usedsponge cleaning device 12 removed from thetether 16, the usedsponge cleaning device 12 can be discarded. The newsponge cleaning device 12 located directly above thesecond retainer 24 is then grasped by the user and pulled with enough force so that thesecond retainer 24 resiliently deforms and the newcleaning sponge device 12 passes over thesecond retainer 24 and into theuse position 26 above thefirst retainer 22. This process continues until there are no remainingsponge cleaning devices 12 held by thetether 16. Thetether 16 can then be reloaded with newsponge cleaning devices 12 if desired. - It is noted that each of the features of the various disclosed embodiments of the present invention can be utilized in any combination with each of the other disclosed embodiments of the present invention.
