A simplified method of sanitizing drinking glasses used in soft drink stands in Israel is described. A pressure spray device served as a pre-rinse and final rinse, while the brushing, detergency and sanitizing phases were combined into one operation by the use of a brush-container filled with a quaternary ammonium based detergent sanitizer. The contact time between the glasses and the sanitizer was from five to ten seconds and satisfactory low bacterial counts were obtained by the swab test method.
