Elliot Parcells & Josh Pohlmann from Bells Brewery tested the efficiency of various sanitizers to kill ''Lactobacillus'', ''Brettanomyces'', and ''Saccharomyces cerevisiae'' var. ''diastaticus''. The sanitizers tested were 100% ethanol, 70% ethanol, isopropyl alcohol, and iodophor at 25 ppm concentration (the recommended no-rinse concentration). With 15 seconds of exposure, both 100% ethanol and 70% ethanol showed no growth. At the maximum time tested, which was 90 seconds, iodophor still showed growth. They found that a concentration of 50 ppm concentration of iodophor at 2 minutes was enough concentration and time to kill ''Lactobacillus'', and 5 minutes for the yeast species tested at 50 ppm. At 75 ppm concentration of iodophor (which is the maximum concentration that is possible to achieve in water due to the equilibrium of free iodine <ref>[http://realbeer.com/jjpalmer/cleaning.html#iodo Palmer, John. A COMPLETE GUIDE TO CLEANING AND SANITATION. RealBeer.com website. Retrieved 07/09/2018.]</ref>), it took 2 minutes to kill all of the microorganisms tested. Across all of the tests, the yeast species were more resistant than the lactic acid bacteria species tested. The ethanol solution remained their preferred sanitizer for spray bottles despite its fast evaporation rate.
