How to Remove Residue Buildup

Key Takeaways:

• Residue buildup in cleanrooms often results from poor rinsing, chemical incompatibility or reliance on non-mechanical cleaning methods, and must be addressed with proper cleaning techniques and validated detergents.
• A 1% v/v solution of ProKlenz™ NpH or ProKlenz™ Booster Sterile Detergent is recommended for effective residue removal, applied using cleanroom techniques and tools like mops, lint-free wipes and sponges.
• The “pull and lift” technique ensures effective surface coverage, especially when cleaning from cleanest to dirtiest areas, and is critical for minimizing cross-contamination.
• Stubborn residues may require scrubbing or more aggressive detergents, and aged or damaged surfaces may need special attention to achieve compliant cleanliness.
