A porous material for insertion cleaning of instruments is provided, such porous material including an at least partially open-cell foam body and a surface configured to enable an instrument having contaminants to be inserted into the body. The body may be configured to substantially grip the instrument to remove a substantial portion of the contaminants from the instrument.

1. A method of cleaning a dental instrument, comprising: providing a foam having an interior region and a surface, wherein the foam has a density of at least approximately 22 kilograms per cubic meter;inserting a dental instrument through the surface and into the interior region, whereby the foam su
1. A method of cleaning a dental instrument, comprising: providing a foam having an interior region and a surface, wherein the foam has a density of at least approximately 22 kilograms per cubic meter;inserting a dental instrument through the surface and into the interior region, whereby the foam substantially grips the dental instrument; andremoving the dental instrument from the foam, whereby bioburdens are removed from the dental instrument after an insertion of the dental instrument into the foam. 2. The method of claim 1, further comprising reducing at least about eighty percent of bioburdens on the dental instrument after a single insertion of the dental instrument into the foam. 3. The method of claim 2, further comprising: reducing over eighty percent of bioburdens on the dental instrument after two insertions of the dental instrument into the foam, andreducing over ninety percent of bioburdens on the dental instrument after three insertions of the dental instrument into the foam, wherein the foam has a density within a range of 20 kg/m3 to 30 kg/m3. 4. The method of claim 1, further comprising holding the foam in an inner cavity of a housing, the foam being configured for placement in the inner cavity of the housing. 5. The method of claim 4, wherein the foam has an air flow through the body of at least 1.0 cubic decimeter per second (dm3/sec). 6. The method of claim 1, wherein the foam has an air flow through the body of at least approximately 1.0 cubic dm3/sec. 7. The method of claim 1, wherein the foam has an air flow through the body within a range of 1.0 dm3/sec to 4.5 dm3/sec. 8. A method of cleaning a contaminated dental instrument, comprising: providing a housing including spaced wall members that define a socket; providing a porous material with a foam body having an interior region and a surface, wherein the body has a density of at least approximately 22 kilograms per cubic meter (kg/m3) and an air flow through the body is at least 1.0 cubic decimeter per second (dm3/sec), the porous material being configured for placement in the socket of the housing;inserting a contaminated dental instrument through the surface and into the interior region, whereby the porous material substantially grips the dental instrument; andremoving the dental instrument from the porous material, whereby bioburdens are removed from the dental instrument after insertion of the dental instrument into the porous material. 9. The method of claim 8, further comprising reducing at least about eighty percent of bioburdens on the dental instrument after a single insertion of the dental instrument into the porous material. 10. The method of claim 8, further comprising: reducing over eighty percent of bioburdens on the dental instrument after two insertions of the dental instrument into the porous material, andreducing over ninety percent of bioburdens on the dental instrument after three insertions of the dental instrument into the porous material, wherein the porous material has a density within a range of 20 kg/m3 to 30 kg/m3. 11. A method of cleaning an endodontic file, comprising: providing an at least partially open-cell foam body having an interior region and a surface, wherein the foam has a density of at least approximately 22 kilograms per cubic meter, a cell count of at least 12 cells per centimeter, and an air flow specification of at least one cubic decimeter per second,inserting an endodontic file partially covered with bioburdens, through the surface and into the interior region of the foam body, whereby the foam substantially grips the file, andremoving the file from the foam, and leaving at least 80% of the bioburdens in the foam separate from the file in a single removing step. 12. The method of claim 11, wherein the density of the foam body is at least 25 kilograms per cubic meter. 13. The method of claim 11, wherein the cell count of the foam body is at least 15 cells per centimeter. 14. A method of cleaning an endodontic file comprising: providing an at least partially open-cell foam body having an interior region and a surface, in a socket member configured for use in an endodontic procedure,inserting a dental instrument partially covered with bioburdens, through the surface and into the interior region of the foam body, whereby the foam substantially grips the file, andremoving the file from the foam, wherein the foam body has a density and cell count selected to permit autoclaving sterilization of a file partially inserted in the cell body, and to retain at least 80% of the bioburdens in the foam body separate from the file in a single removing step. 15. The method of claim 14, wherein the density of the foam body is at least 20 kilograms per cubic meter. 16. The method of claim 14, wherein the density of the foam body is at least 22 kilograms per cubic meter. 17. The method of claim 14, wherein the cell count of the foam body is at least 12 cells per centimeter. 18. The method of claim 14, wherein the cell count of the foam body is at least 15 cells per centimeter. 19. The method of claim 14, wherein the foam body has an air flow specification of at least 3 decimeters cubed per second. 20. A method of cleaning an endodontic file comprising: providing an at least partially open-cell foam body having an interior region and a surface, in a socket member configured for use in an endodontic procedure,inserting a dental instrument through the surface and into the interior region of the foam body, whereby the foam substantially grips the file,autoclaving the dental instrument along with the foam body, the foam body having a density and cell count selected to permit sterilization of the file through the cell body structure,withdrawing the file from the foam body, using the file in an endodontic procedure, and accumulating bioburdens on the file,reinserting the file partially covered with bioburdens, through the surface and into the interior region, whereby the foam substantially grips the file, andremoving the file from the foam, wherein the density and cell count of the foam body provide retention of at least 80% of the bioburdens in the foam body separate from the file in a single removing step.
