Claim: 1-9. (canceled)
Claim: 10. A mold cleaning material of sheet form comprising at least two base sheets, and a combination of a cleaning member and a molding member enclosed between the base sheets; wherein the cleaning member has at least one of a tablet form, a granular form, a powder form, a sheet form, and a plate form, and the molding member is at least one of unvulcanized synthetic rubber and unvulcanized natural rubber.
Claim: 11. The mold cleaning material according to claim 10, wherein at least the outermost base sheets are fibrous sheets having a porosity of 70% or more.
Claim: 12. The mold cleaning material according to claim 10, which has a thermoplastic resin film or tape applied to a prescribed part of at least one of the base sheets.
Claim: 13. The mold cleaning material according to claim 10, wherein a combination of the cleaning member and the molding member is enclosed by heat sealing the base sheets via a thermoplastic resin film or tape.
Claim: 14. The mold cleaning material according to according to claim 10, wherein a combination of the cleaning member and the molding member is enclosed by adhering the base sheets with at least one of a double-sided tape, an adhesive, and a pressure sensitive adhesive.
Claim: 15. The mold cleaning material according to claim 10, wherein a combination of the cleaning member and the molding member is enclosed by adhering the base sheets by pressing or deforming the base sheets.
Claim: 16. A method of cleaning a mold comprising the steps of sandwiching a mold cleaning material according to claim 10 between two halves of a heated mold, applying heat and pressure to the mold cleaning material for a given time to cure the cleaning member, and removing the cleaning material.
Claim: 17. The mold cleaning material according to claim 11, which has a thermoplastic resin film or tape applied to a prescribed part of at least one of the base sheets.
Claim: 18. The mold cleaning material according to claim 11, wherein a combination of the cleaning member and the molding member is enclosed by heat sealing the base sheets via a thermoplastic resin film or tape.
Claim: 19. The mold cleaning material according to claim 12, wherein a combination of the cleaning member and the molding member is enclosed by heat sealing the base sheets via a thermoplastic resin film or tape.
Claim: 20. The mold cleaning material according to according to claim 11, wherein a combination of the cleaning member and the molding member is enclosed by adhering the base sheets with at least one of a double-sided tape, an adhesive, and a pressure sensitive adhesive.
Claim: 21. The mold cleaning material according to according to claim 12, wherein a combination of the cleaning member and the molding member is enclosed by adhering the base sheets with at least one of a double-sided tape, an adhesive, and a pressure sensitive adhesive.
Claim: 22. The mold cleaning material according to claim 11, wherein a combination of the cleaning member and the molding member is enclosed by adhering the base sheets by pressing or deforming the base sheets.
Claim: 23. The mold cleaning material according to claim 12, wherein a combination of the cleaning member and the molding member is enclosed by adhering the base sheets by pressing or deforming the base sheets.
Claim: 24. A method of cleaning a mold comprising the steps of sandwiching a mold cleaning material according to claim 11 between two halves of a heated mold, applying heat and pressure to the mold cleaning material for a given time to cure the cleaning member, and removing the cleaning material.
Claim: 25. A method of cleaning a mold comprising the steps of sandwiching a mold cleaning material according to claim 12 between two halves of a heated mold, applying heat and pressure to the mold cleaning material for a given time to cure the cleaning member, and removing the cleaning material.
Claim: 26. A method of cleaning a mold comprising the steps of sandwiching a mold cleaning material according to claim 13 between two halves of a heated mold, applying heat and pressure to the mold cleaning material for a given time to cure the cleaning member, and removing the cleaning material.
Claim: 27. A method of cleaning a mold comprising the steps of sandwiching a mold cleaning material according to claim 14 between two halves of a heated mold, applying heat and pressure to the mold cleaning material for a given time to cure the cleaning member, and removing the cleaning material.
Claim: 28. A method of cleaning a mold comprising the steps of sandwiching a mold cleaning material according to claim 15 between two halves of a heated mold, applying heat and pressure to the mold cleaning material for a given time to cure the cleaning member, and removing the cleaning material.
