Methods are provided for making a treatment composition by loading active components into a high pressure vessel and pressurizing the high pressure vessel with carbon dioxide to reach a pressure within the high pressure vessel of about 400 pounds per square inch to about 1,070 pounds per square inch
Methods are provided for making a treatment composition by loading active components into a high pressure vessel and pressurizing the high pressure vessel with carbon dioxide to reach a pressure within the high pressure vessel of about 400 pounds per square inch to about 1,070 pounds per square inch. The active components can include a protein denaturant and a surfactant, and optionally an acaricide. In one particular embodiment, this method can be used to clean a substrate, by loading the substrate into the high pressure vessel prior to pressurizing with carbon dioxide. Methods are also provided for treating a substrate to clean it from dust mites by delivering dry ice particles to the substrate, and vacuuming the substrate. Treatment compositions are also generally provided.

1. A method for cleaning a substrate, the method comprising: delivering a treatment composition to the substrate to loosen debris particles from the substrate, wherein the treatment composition comprises carbon dioxide, an acaricide, and a surfactant, the carbon dioxide being frozen into dry ice particles; andvacuuming the substrate to remove the loosened particles from the substrate. 2. The method of claim 1, wherein the dry ice particles further comprise the surfactant. 3. The method of claim 2, further comprising: prior to delivering the treatment composition to the substrate, mixing the surfactant with liquid carbon dioxide; andfreezing the treatment composition into the dry ice particles such that the dry ice particles comprise the carbon dioxide and the surfactant. 4. The method of claim 3, wherein the treatment composition further comprises a protein denaturant. 5. The method of claim 4, wherein the protein denaturant comprises ethanol, hydrogen peroxide, benzyl benzoate, tannic acid, or a mixture thereof. 6. The method of claim 1, wherein the surfactant is delivered as a liquid. 7. The method of claim wherein the surfactant is delivered as a solid particulate. 8. The method of claim 1, wherein the surfactant is configured to clean the substrate. 9. The method of claim 1, wherein the surfactant comprises a fluorosurfactant, an ionic surfactant, a silicon-based surfactant, a hydrocarbon surfactant, or a mixture thereof. 10. The method of claim 1, wherein the substrate is vacuumed after a time sufficient to allow the dry ice particles to sublime. 11. The method as in claim 1, wherein dry ice particles further comprise the acaricide. 12. The method as in claim 1, wherein the acaricide comprises permethrin, benzyl benzoate, or a mixture thereof. 13. The method as in claim 1, wherein the carbon dioxide has a purity of about 90% by volume or more. 14. The method as in claim 1, wherein the surfactant is present in the treatment composition in a concentration of about 0.001% to about 3% by volume. 15. The method as in claim 1, wherein the substrate is a carpet. 16. The method as in claim 1, wherein the substrate is a fabric. 17. The method as in claim 1, wherein the substrate is a mattress. 18. The method as in claim 1, further comprising: prior to delivering the treatment composition to the substrate, mixing the acaricide with liquid carbon dioxide; andfreezing the treatment composition into the dry ice particles such that the dry ice particles comprise the carbon dioxide and the acaricide. 19. A method for cleaning a carpet, the method comprising: delivering a treatment composition to the carpet to loosen debris particles from the carpet, wherein the treatment composition comprises carbon dioxide, and a surfactant, the carbon dioxide being frozen into dry ice particles; andvacuuming the carpet to remove the loosened particles from the carpet. 20. The method of claim 19, wherein the dry ice particles further comprise the surfactant. 21. The method of claim 20, further comprising: prior to delivering the treatment composition to the carpet, mixing the surfactant with liquid carbon dioxide; andfreezing the treatment composition into the dry ice particles such that the dry ice particles comprise the carbon dioxide and the surfactant. 22. The method of claim 21, wherein the treatment composition further comprises a protein denaturant. 23. The method of claim 22, wherein the protein denaturant comprises ethanol, hydrogen peroxide, benzyl benzoate, tannic acid, or a mixture thereof. 24. The method of claim 19, wherein the surfactant is delivered as a liquid. 25. The method of claim 19, wherein the surfactant is delivered as a solid particulate. 26. The method of claim 19, wherein the surfactant is configured to clean the carpet. 27. The method of claim 19, wherein the surfactant comprises a fluorosurfactant, an ionic surfactant, a silicon-based surfactant, a hydrocarbon surfactant, or a mixture thereof. 28. The method of claim 19, wherein the carpet is vacuumed after a time sufficient to allow the dry ice particles to sublime. 29. The method of claim 19, wherein the treatment composition further comprise an acaricide. 30. The method of claim 29, wherein the acaricide comprises permethrin, benzyl benzoate, or a mixture thereof. 31. The method of claim 19, wherein the carbon dioxide has a purity of about 90% by volume or more. 32. The method of claim 19, wherein the surfactant is present in the treatment composition in a concentration of about 0.001% to about 3% by volume. 33. A method for cleaning a mattress, the method comprising: delivering a treatment composition to the carpet to loosen debris particles from the mattress, wherein the treatment composition comprises carbon dioxide, and a surfactant, the carbon dioxide being frozen into dry ice particles; andvacuuming the mattress to remove the loosened particles from the mattress.
