Overview
This SOP defines which brush from a shake machine cleaning kit is used on each port, seal, surface, and removable part. It is designed for equipment maintenance and sanitation teams that need a repeatable way to clean food-contact equipment without damaging soft seals or pushing debris into tight openings.
Use this template when your shake machine has multiple component types that require different brush sizes or stiffness levels, or when cross-use of tools has caused contamination, wear, or inconsistent cleaning results. It is especially useful for shift-based operations, multi-unit restaurants, and sites that need a clear record of who cleaned what and whether any deviation was found.
Do not use this SOP as a substitute for the manufacturer’s cleaning instructions, lockout/tagout, or any required permit-to-work process. If a port is cracked, a gasket is swollen, a brush is shedding bristles, or the machine must be opened beyond routine cleaning access, stop and escalate to maintenance or a competent person. The template is also not the right fit for chemical descaling, electrical repair, or disassembly beyond the normal cleaning scope. Its purpose is narrow and practical: assign the right brush to the right component, verify the tools are clean and serviceable, and record exceptions before they become non-conformances.
Standards & compliance context
- This template supports ISO 9001-style documented information by defining a repeatable method, assigned roles, and recorded deviations.
- It aligns with food safety sanitation controls commonly expected under GMP and HACCP programs by reducing cross-contamination risk during cleaning.
- If your site uses manufacturer sanitation instructions, this SOP should be controlled as a local work instruction that does not override approved equipment guidance.
- Where cleaning occurs after a hazardous intervention or exposed moving parts, pair this SOP with lockout/tagout or permit-to-work requirements before starting.
- If your operation uses inspection records for audits, keep the brush map and deviation log together so the cleaning trail is easy to verify.
General regulatory context for orientation only — verify current requirements with counsel or the relevant agency before relying on this template for compliance.
What's inside this template
Steps
This section matters because it turns the brush map into a repeatable cleaning sequence with clear ownership and verification.
-
Verify lockout/tagout is in place
The technician confirms the machine is isolated and the LOTO tag is present before any cleaning begins.
-
Verify the machine is cool, depressurized, and ready for cleaning
The technician checks that the machine has cooled to a safe handling temperature and that any pressure has been relieved before opening access points.
-
Identify each brush by assigned component
The technician reviews the machine cleaning map and labels each brush by its assigned component before use. The technician confirms that the narrow brush is assigned only to small ports, the seal brush only to gaskets and soft seals, the medium brush only to accessible machine surfaces, and the large brush only to removable parts and wider channels.
-
Assign the narrow brush to small ports and tight openings
The technician uses the narrow brush only on ports and openings that match the brush profile without forcing the bristles or handle. The technician stops and selects a different tool if the brush does not enter smoothly or if the opening shows resistance, deformation, or incomplete contact.
-
Assign the seal brush to gaskets and soft seals
The technician uses the seal brush only on gaskets and soft seals and applies light, controlled pressure to avoid nicking or stretching the material. The technician stops immediately if any seal shows tearing, distortion, or visible wear after brushing.
-
Assign the medium brush to accessible machine surfaces
The technician uses the medium brush only on accessible machine surfaces and cleans each surface until no visible soil, residue, or streaking remains. The technician does not use the medium brush on ports, seals, or tight openings.
-
Assign the large brush to removable parts and wider channels
The technician uses the large brush only on removable parts and wider channels that can accept the brush without contacting seals or narrow openings. The technician confirms that all cleaned areas are free of visible residue and that the brush never touches soft sealing surfaces.
-
Inspect brushes for contamination and wear
The technician inspects each brush under task lighting for bristle loss greater than 10%, discoloration, embedded debris, bent bristles, cracked handles, or residue that cannot be removed by rinsing. The technician removes any brush that fails inspection from service immediately.
-
Record any deviation or non-conformance
The technician records any brush mismatch, contamination, bristle loss greater than 10%, seal damage, or other cleaning deviation in the non-conformance log before closing the job. The technician escalates the issue to the supervisor if more than two brushes are unfit for service or if any component damage is observed.
How to use this template
- 1. The supervisor confirms the shake machine is isolated, safe to clean, and cleared for routine sanitation before any brush is selected.
- 2. The operator reviews the brush map and identifies each brush by color, size, or label against the assigned port, seal, surface, or removable part.
- 3. The operator uses the narrow brush only for small ports and tight openings, the seal brush only for gaskets and soft seals, the medium brush for accessible machine surfaces, and the large brush for removable parts and wider channels.
- 4. The operator inspects each brush for contamination, worn bristles, loose handles, or embedded debris before and after use, and removes any defective brush from service.
- 5. The operator records any deviation, non-conformance, damaged component, or brush mismatch in the log and escalates unresolved issues to the shift lead or maintenance role.
Best practices
- Label each brush by component type and keep the labels visible at the point of use.
- Photograph the brush set and the machine ports during setup so new staff can match the map without guessing.
- Use the seal brush only on gaskets and soft seals, because stiffer brushes can deform sealing surfaces and create leaks.
- Replace any brush that sheds bristles, holds residue after cleaning, or no longer matches the assigned component.
- Keep the brush map aligned with the exact machine model, since port size and seal geometry often vary by unit.
- Record a deviation immediately if an operator uses the wrong brush, even if no visible damage is found.
- Separate cleaning tools from maintenance tools so the sanitation kit does not become contaminated by repair work.

Common use cases
Frequently asked questions
What does this SOP cover?
It covers brush-to-component assignments for a shake machine cleaning kit, including small ports, gaskets, soft seals, accessible surfaces, and removable parts. It also includes pre-clean safety checks, brush inspection, and deviation logging. The goal is to prevent cross-use, contamination, and seal damage during routine cleaning.
Who should use this template?
A trained operator, shift lead, or competent person responsible for sanitation can use it. It works best when the same role owns the brush mapping and the final verification step. If your site uses separate cleaning and maintenance roles, the SOP can be split so each role signs only the steps they perform.
How often should the brush mapping be used?
Use it every time the shake machine is cleaned, not only during deep cleans. If your operation has multiple cleaning frequencies, keep the same brush map for daily, shift-change, and post-maintenance cleaning unless the equipment design changes. Revisit the map whenever ports, seals, or brush types change.
Does this help with food safety or sanitation compliance?
Yes. It supports documented sanitation controls, traceable cleaning practices, and consistent handling of food-contact components. The template can also help with GMP-style expectations, HACCP sanitation controls, and ISO 9001 documented information practices by showing what was cleaned, with what tool, and by whom.
What are the most common mistakes this SOP prevents?
The most common failures are using the wrong brush on a soft seal, reusing a contaminated brush on a food-contact port, and skipping brush inspection before cleaning. Another frequent issue is failing to record worn bristles or a damaged gasket, which can turn a cleaning task into a maintenance issue. This SOP makes those checks explicit.
Can I customize the brush map for different machine models?
Yes. The template is meant to be edited for your exact machine layout, brush sizes, and cleaning chemicals. Add model-specific port names, component photos, and any manufacturer restrictions so operators do not have to guess. If you run multiple models, create one map per model rather than one generic version.
Should this SOP be linked to other procedures?
It should connect to your sanitation SOP, pre-use inspection checklist, maintenance escalation process, and non-conformance log. If your site uses permit-to-work or lockout/tagout before cleaning, reference those steps in the safety section. Linking the documents helps operators move from cleaning to escalation without losing context.
How is this better than relying on memory or ad-hoc cleaning?
Memory-based cleaning creates variation, especially across shifts and new hires. This template gives each brush a fixed purpose, which reduces seal wear, missed spots, and contamination from tool sharing. It also creates a record when the machine design or brush condition forces a deviation.
