We are starting to see high counts on our Y/M plates that we do on a monthly basis. We recently acquired an older building that has an older ventilation system. We make products in a high temperature room that produces moisture , which we think is accumulating in these vents and creating a higher count for Y/M.
We think we can Fog the vents to clean them and hopefully this will reduce the counts but we were also wondering what is the best chemical to use for Y/M ?
I would like to know what people use for prevention on walls in production rooms (mainly ones that are also outside walls) and what people use to clean the Y/M if seen. Some say quat is the best, but I think otherwise.
Any comments would be helpful! thanks!
