Cleanroom Mop Procedure – How to Mop a Cleanroom with a Multi-Bucket System

Cleanroom mop systems are one of the most fundamental aspects of maintaining ISO class or cGMP cleanliness levels. Cleanroom mops feature design and materials that provide an economical, easier, and more consistent cleaning procedure which leaves the least possible amount of residual contaminants.

Finding the Best Cleanroom Mop Materials

Disinfection or wipedown in a cleanroom requires specialized mop head materials that inhibit the introduction of additional bioburdens, particulate, contaminants, or residues. High-quality fabrics with easy swap designs offer a wide scope of chemical compatibility with minimal shedding or fraying. An ideal cleanroom mop system dislodges any residue or biofilm which could impede the effectiveness of cleaners and solvents. Woven or double knit polyester fabrics provide the highest degree of strength with minimal particle shed. Abrasiveness, absorption characteristics, fluid retention, ease of sanitation, and chemical compatibility all contribute to the effectiveness of a cleanroom mop system. It is essential that cleaners and solvents offer compatibility with a mop fabric. Improper solvents may cause degradation when mixed with fabric substrates.

How to Mop a Cleanroom Effectively with a Multi-Bucket Cleanroom Mopping System

Reapplying dirty water to a surface is never optional in a cleanroom, but is unavoidable with a single bucket mop system. Multi-bucket cleanroom mop systems provide a dedicated bucket for sanitation, clean rinse, and dirty rinse. One bucket provides a clean disinfectant, one a rinse disinfectant, and the last server as a waste bucket. Starting with the cleanest possible water is essential, opt for either distilled or ionized.

  1. Wet the mop from clean solution bucket
  2. Remove excess solution into waste bucket
  3. Perform mopping process
  4. Remove contaminated solution into waste bucket
  5. Dip mop into rinse bucket
  6. Remove excess water into waste bucket
  7. Reapply solution
  8. Remove excess solution into waste bucket
