I make flexible packaging too. I've got my first SQF audit this April/May so I don't speak from much experience. We were AIB for the last 10 years.
I have chosen verify/validate cleaning with visual inspection and not by swabbing on the basis that the material is low risk. It's not like you're dealing with raw meat, or milk, or some other food or material that micro like to grow on.
We use what we call Master Cleaning Schedules for each machine/work-cell. This document is a form that lists all the cleaning tasks in an area, who does it, frequency, and how to do it (cleaning equipment, chemicals, etc.). Then there is a spot for initials and date for each cleaning task, and final a supervisor does a monthly verification and signs off when complete. We verify/validate with monthly self-inspection. It's all just visual though.
We also have cleaning procedures for product contact surfaces like rollers, idlers, anallox rollers, lift tables, etc. We typically clean with a cleaner/detergent, then water rinse, then a solvent. This type of cleaning only happens between campaigns (~every 2 weeks) where we do a major machine tear down and set up. We have a sign off sheet to record that the work was done and then a supervisor verifies (visual inspection) and signs off, then we set up for the next campaign.
We also do cleaning of equipment and utensils (ink pumps, primer sumps, splash guards, etc.). We have procedures for these but currently don't keep records of the cleaning and don't have verification. I'm evaluating the need to record this cleaning.
Per 13.2.11 Cleaning and Sanitation
1 - "The methods and responsibility for the cleaning of manufacturing and storage areas, staff amenities and toilet facilities shall be documented and implemented."
2 - "Provision shall be made for the effective cleaning of processing equipment, utensils and protective clothing."
Not sure if I only need to document "cleaning of manufacturing and storage areas", or by "Provision shall be made" SQF means cleaning of processing equipment needs to be documented too. Are you documenting this type of cleaning nbobrowicz?
