Do Not Let Cleaning Logs Exceed Capacity Before Replacement

Replace Cleaning Logs Promptly Before Reaching Capacity

Remember: Cleaning logs should be replaced before they’re completely filled—GMP requires continuous documentation without record overflow or loss of traceability.

Why This Matters in GMP

Cleaning logs are critical documents in GMP environments, providing traceability of equipment hygiene, facility sanitation, and compliance with cleaning schedules. If these logs are allowed to exceed their capacity, operators may be forced to use margins, blank areas, or attach unofficial pages—jeopardizing documentation integrity and violating GDP (Good Documentation Practices). Overflowing logs also make record review difficult and increase the risk of missed entries, illegible data, or backdated information. GMP emphasizes pre-emptive record management to ensure continuous, auditable, and structured documentation across all functions.

Regulatory and Compliance Implications

FDA 21 CFR Part 211.180 mandates accurate, timely, and complete recordkeeping in all areas, including cleaning. EU GMP Chapter 4 highlights the need for controlled documents with traceable data entry and no overwriting. WHO GMP and Schedule M also require cleaning records to be appropriately maintained, reviewed, and archived. During audits, regulators check for proper documentation control, including whether logs are replaced on time, have adequate space, and follow version control. Overflowed or backdated cleaning

logs may result in GDP violations and remediation orders.

Implementation Best Practices

Monitor logbook usage regularly and flag when pages fall below a minimum threshold for replacement.
Establish SOPs defining how many entries a cleaning log should accommodate before replacement is mandatory.
Ensure each new logbook is sequentially numbered and cross-referenced to the one it replaces.
Train personnel to never use blank margins or post-its to continue entries when pages run out.
Maintain a logbook issuance register controlled by QA, including issuance date, department, and equipment ID.
