This cleaning system checklist covers what a CIP audit actually inspects, aligned with 3-A Sanitary Standards hygienic design principles. Use this checklist to organize system layout, circuit lists, cycle logic, chemistry, temperature, return confirmation, procedures, records, and symptoms.
Cleaning problems are easy to oversimplify. The useful starting point is a factual packet: circuits, timing, chemistry, flow, return confirmation, valve logic, operator steps, records, and symptoms.
Solon’s CIP consulting service audits and redesigns cleaning systems. Send this packet with your inquiry and a Solon engineer replies by email, usually within one business day.
Field note
Start with evidence, not redesign assumptions
A new skid, valve cluster, or control recipe may be needed, but the checklist should first separate observed symptoms from assumptions.
The review becomes stronger when operators can show what the system is supposed to do, what it actually does, and which records are available. Alarms and corrective actions should trace back to brewery SOPs that operators actually follow.
Cleaning-system review inputs
Work through it and you will arrive at the review with the evidence that actually explains the problem, instead of a description of the symptom.
Checklist area
What to gather
Why it matters
Layout
circuits, tanks, spray devices, return path
shows what can be cleaned and verified
Cycles
steps, time, temperature, chemistry, flow
separates procedure from equipment risk
Controls
valves, permissives, instruments, alarms
identifies automation and confirmation gaps
Records
procedures, logs, swabs, ATP or validation context
frames available evidence
Cleaning System Review Checklist
Complete this checklist before a sanitation review, before troubleshooting a recurring contamination issue, or before commissioning a new CIP system. Incomplete answers indicate where the investigation needs to start.

This checklist is a preparation tool, not a substitute for engineering review. If completing this checklist surfaces questions you cannot answer, that is the right time to involve a consultant. Contact Solon to discuss your project.
Pair this checklist with the CIP chemical dosing calculator to check whether wash-step chemistry matches what the audit finds.
