The method includes cleaning and sanitizing the cylinders and substituting the cleaned and sanitized cylinders for used cylinders that have not recently been cleaned and sanitized. ## Claims ### Claim 1 A method for supplying clean, sanitized cylinders to a bank's customers comprising the steps of: exchanging used drive-up teller cylinders for cleaned cylinders; washing the used cylinders with a cleaning solution; drying the cleaned cylinders; packaging the cleaned cylinders to maintain their clean condition; and returning the cleaned cylinders to the bank and exchanging the cleaned cylinders for the set of cylinders to be cleaned; wherein the method further comprises cleaning a pneumatic transit tube by causing a pig to be transported through the transit tube, wherein the pig is sized and shaped to compressibly fit within the transit tube with tolerances as to create a pneumatic seal between the exterior wall of the pig and the interior wall of the transit tube and wherein the pig is coated with a disinfectant prior to being transported through the transit tube. ### Claim 2 (depends on 1) The method of claim 1, further comprising placing a sticker at or near a customer access point of a drive up teller for informing the customer that the cylinders are cleaned and disinfected. ### Claim 3 (depends on 1) The method of claim 1 wherein the cleaning solution comprises one or more disinfectants having one or more of the following disinfectant active ingredients: alcohols, aldehydes, oxidizing agents (such as chlorine and oxygen), quaternary ammonium compound, phenolics, or other known disinfecting/sanitizing compounds. ### Claim 4 (depends on 1) The method of claim 1 wherein the pig is covered with an absorbent material. ### Claim 5 (depends on 1) The method of claim 1 wherein the cylinders are exchanged at least once a week. ### Claim 6 A method for supplying clean, sanitized cylinders to a bank's customers comprising the steps of: exchanging used drive-up teller cylinders for cleaned cylinders; washing the used cylinders with a cleaning solution; drying the cleaned cylinders; packaging the cleaned cylinders to maintain their clean condition; and returning the cleaned cylinders to the bank and exchanging the cleaned cylinders for the set of cylinders to be cleaned; wherein the method further comprises placing a sticker at or near a customer access point of a drive up teller for informing the customer that the cylinders are cleaned and disinfected. ### Claim 7 (depends on 6) The method of claim 6, further comprising cleaning a pneumatic transit tube by causing a pig to be transported through the transit tube, wherein the pig is sized and shaped to compressibly fit within the transit tube with tolerances as to create a pneumatic seal between the exterior wall of the pig and the interior wall of the transit tube and wherein the pig is coated with a disinfectant prior to being transported through the transit tube. ### Claim 8 (depends on 7) The method of claim 7 wherein the pig is covered with an absorbent material. ### Claim 9 (depends on 6) The method of claim 6 wherein the cleaning solution comprises one or more disinfectants having one or more of the following disinfectant active ingredients: alcohols, aldehydes, oxidizing agents (such as chlorine and oxygen), quaternary ammonium compound, phenolics, or other known disinfecting/sanitizing compounds. ### Claim 10 (depends on 6) The method of claim 6 wherein the cylinders are exchanged at least once a week. ### Claim 11 A method for supplying clean, sanitized cylinders to a bank's customers comprising the steps of: exchanging used drive-up teller cylinders for cleaned cylinders; washing the used cylinders with a cleaning solution; drying the cleaned cylinders; packaging the cleaned cylinders to maintain their clean condition; and returning the cleaned cylinders to the bank and exchanging the cleaned cylinders for the set of cylinders to be cleaned; wherein the method further comprises cleaning a pneumatic transit tube by causing a pig to be transported through the transit tube, wherein the pig is covered with an absorbent material and is sized and shaped to compressibly fit within the transit tube with tolerances as to create a pneumatic seal between the exterior wall of the pig and the interior wall of the transit tube and wherein the pig is coated with a disinfectant prior to being transported through the transit tube. ### Claim 12 (depends on 11) The method of claim 11, further comprising placing a sticker at or near a customer access point of a drive up teller for informing the customer that the cylinders are cleaned and disinfected. ### Claim 13 (depends on 11) The method of claim 11 wherein the cleaning solution comprises one or more disinfectants having one or more of the following disinfectant active ingredients: alcohols, aldehydes, oxidizing agents (such as chlorine and oxygen), quaternary ammonium compound, phenolics, or other known disinfecting/sanitizing compounds. ### Claim 14 (depends on 11) The method of claim 11 wherein the cylinders are exchanged at least once a week.
