Mops and Buckets

Compiled by Ryan Cliche

If you overlook mops and buckets, you might trip over them. However, it is much more disastrous to trip over soil load and bioburden in your cleanroom, a result of overlooking the use of mops and buckets. Multiple buckets should be employed to prevent redeposition of soil. The principle with the two or three bucket routine is that soil deposited in the use-dilution not only inactivates the solution, but also may be deposited via the mop onto other cleanroom surfaces. Therefore, if the mop, once used, is never deposited into the use-dilution without first being rinsed and wrung out in a separate chamber, one which holds either clean water or separate use-dilution, the primary use-dilution chamber will be maintained longer without risk of depositing soil onto cleanroom surfaces via the solution. The following mop and bucket products are designed to help avoid this redeposition and minimize bioburden.
