Cleaning standards and tool selection for a Class 100 cleanroom

Posted on by

Maintaining a Class 100 (ISO 5) cleanroom requires strict cleaning protocols and carefully selected tools. Proper practices ensure minimal particle contamination, protect sensitive equipment, and comply with regulatory standards.

Key Features:

  • Standardized Cleaning Protocols: Define cleaning frequency, techniques, and surface priorities to maintain Class 100 cleanliness.

  • Lint-Free and Antistatic Tools: Use wipes, mops, and swabs that do not shed fibers and prevent electrostatic discharge (ESD).

  • Chemical Compatibility: Tools must withstand cleaning agents such as IPA, deionized water, and approved disinfectants without degradation.

  • Specialized Equipment: Include HEPA-filtered vacuums, microfiber mops, and pre-wetted wipes for effective particle removal.

Tool Selection Guidelines:

  • Wipes: Lint-free, antistatic wipes for surfaces, instruments, and benches.

  • Mops: High-density microfiber mops for floors and larger surfaces.

  • Swabs: Precision swabs for corners, crevices, and delicate equipment.

  • Containers and Storage: Sealed, clean containers for storing wipes and tools to maintain sterility.

Applications:

  • Semiconductor Manufacturing: Maintains particle-free workstations and sensitive components.

  • Pharmaceutical Cleanrooms: Ensures compliance with hygiene and sterility standards.

  • Laboratories: Cleans benches, instruments, and glassware without contamination.

  • Optical and Electronics Assembly: Protects lenses, PCBs, and other precision equipment.

Benefits:

  • Maintains Cleanroom Standards: Minimizes particle contamination and ensures regulatory compliance.

  • Protects Sensitive Equipment: Lint-free, antistatic tools reduce damage and ESD risk.

  • Improves Cleaning Efficiency: Standardized protocols and proper tools save time and maintain effectiveness.
