Detergents and disinfectants for use on cleanroom surfaces (walls, floors) must be applied using the double or triple-bucket system to avoid cross contamination. Both of these techniques involve using a bucket of disinfectant and a bucket of water. In the “two-bucket” technique there is a “wringer” (for the mop) over the bucket of water. In the “three-bucket” technique there is a third bucket, empty except for having a wringer mounted over it.
This cleanroom tip was taken from “Cleanroom Cleaning and Disinfection: Eight Steps for Success,” which appeared in the March 2012 issue of Controlled Environments.
