With dry methods being ineffective¹, the double or triple bucket system should be deployed when cleaning and disinfecting cleanrooms. 

It has been demonstrated that the triple-bucket system, which uses two buckets of disinfectant or detergent and one empty bucket, improves the effectiveness of the cleaning and disinfection of a cleanroom (as well as healthcare facilities²). This is further enhanced with the use of a mechanical wringer³.

It is therefore recommended that use of a triple bucket system should be considered in high grade cleanrooms (EU GMP Grade A and B, as well as C areas containing isolators). In this article, the case for the triple bucket system is set out.
