A twisted wire brush comprises a wire core and at least one length of spring coil. The wire core has a first length, defines a core axis, and comprises at least two core wires intertwined. The core wires twist helically about the core axis. Each length of spring coil extends about at least one of the core wires, and each length of spring coil is pressed between the twisted core wires. In another embodiment, a method of making a twisted wire brush comprises providing at least two core wires, positioning a length of spring coil about each core wire, aligning each length of spring coil, and twisting each core wire about a core axis. In yet another embodiment, a grill brush comprises a handle, a plurality of twisted core wires attached to the handle, and at least one length of spring coil, each length extending about at least one core wire.

1. A twisted wire brush comprising: a twisted wire core having a first length, a core axis, and at least two core wires intertwined, the at least two core wires twisting helically about the core axis; andat least two lengths of spring coil, at least one length of each spring coil extending about each core wire, each length of spring coil being pressed between the core wires, whereineach spring coil comprises a plurality of consecutive 360 degree turns about a coil axis of each spring coil, andeach length of spring coil is compressed axially such that at least a portion of each consecutive 360 degree turn around the coil axis of each springy coil abuts in an axial direction to an immediately preceding consecutive 360 degree turn. 2. A twisted wire brush as recited in claim 1, wherein each length of spring coil comprises multiple consecutive spring coils. 3. A twisted wire brush as recited in claim 1, wherein each length of spring coil comprises a single spring coil. 4. A twisted wire brush as recited in claim 1, wherein a first length of spring coil extending about a first core wire defines a first spring coil diameter, a second length of spring coil extending about a second core wire defines a second spring coil diameter, and the first spring coil diameter is different than the second spring coil diameter. 5. A twisted wire brush as recited in claim 1, wherein a first length of spring coil extending about a first core wire and a second length of spring coil extending about a second core wire have the same spring coil diameter. 6. A twisted wire brush as recited in claim 1, wherein at least one of the lengths of spring coil has a diameter that varies. 7. A method of making a twisted wire brush, the method comprising: providing at least two core wires and at least two lengths of spring coil;positioning a length of each spring coil about each core wire so that each core wire extends through the respective length of spring coil, each length of spring coil having a first end and a second end;aligning each length of spring coil positioned about one of the core wires adjacent to another length of spring coil positioned about another of the core wires, so that each first end of each length of spring coil is aligned and each second end of each spring coil is aligned; andtwisting each core wire about a core axis to form a helix, to intertwine the core wires, and to press the lengths of spring coil between adjacent core wires, whereineach spring coil comprises a plurality of consecutive 360 degree turns about a coil axis of each spring coil, andeach length of spring coil is compressed axially such that at least a portion of each consecutive 360 degree turn around the coil axis of each spring coil abuts in an axial direction to an immediately preceding consecutive 360 degree turn. 8. A method of making a twisted wire brush as recited in claim 7, wherein the method further comprises twisting each core wire until a predetermined value of torque on the core wires is reached. 9. A method of making a twisted wire brush as recited in claim 7, wherein each length of spring coil comprises multiple consecutive spring coils. 10. A method of making a twisted wire brush as recited in claim 7, wherein each length of spring coil comprises a single spring coil. 11. A method of making a twisted wire brush as recited in claim 7, wherein a first length of spring coil defines a first spring coil diameter, a second length of spring coil defines a second spring coil diameter, and the first spring coil diameter is different than the second spring coil diameter. 12. A method of making a twisted wire brush as recited in claim 7, wherein a first length of spring coil and a second length of spring coil each define a single spring coil diameter. 13. A method of making a twisted wire brush as recited in claim 7, wherein at least one of the lengths of spring coil has a diameter that varies. 14. A twisted wire grill brush comprising: a handle;a plurality of twisted core wires attached to the handle, the plurality of core wires being intertwined and twisted about a core axis;at least two lengths of spring coil, each length of spring coil respectively extending superimposed about each of at least two core wires, each length of spring coil being pressed between the twisted core wires, whereineach spring coil comprises a plurality of consecutive 360 degree turns about a coil axis of each spring coil,each length of spring coil is compressed axially such that at least a portion of each consecutive 360 degree turn around the coil axis of each spring coil abuts in an axial direction to an immediately preceding consecutive 360 degree turn, andthe handle extends substantially perpendicularly to the at least two lengths of spring coil.
