Quick answer
Clean food-contact surfaces before disinfecting them, using suitable products and the manufacturer’s instructions for dilution, contact time and any rinsing. Remove or protect food while the work is done and prevent recontamination afterwards. There is no universal chemical recipe for every surface, organism and task.
Cleaning and disinfection do different jobs
Cleaning removes dirt, grease and food debris. Disinfection reduces relevant microorganisms after effective cleaning. Applying a disinfectant over a dirty surface can leave the process ineffective.
The SFBB cleaning method explains this two-stage approach. GOV.UK’s business guidance also covers cleaning schedules and product suitability.
Check the product before using it
| Check | What to establish |
|---|---|
| Intended use | Suitability for the surface and food-area task. |
| Standard and claim | The relevant standard and what the product actually controls. |
| Dilution | The exact preparation required by its instructions. |
| Contact time | How long the treatment must remain effective on the surface. |
| Rinsing and drying | What must happen before food work resumes. |
| Worker protection | Handling precautions and equipment required by the instructions. |
Official guidance identifies BS EN 1276 or BS EN 13697 for relevant disinfectant checks. A standard number does not prove that one product controls every virus, allergen or contamination type. Read the full instructions and the business’s assessment.
Write a practical task-specific sequence
- Remove or protect food and prepare the area safely.
- Remove loose debris and use the appropriate cleaning method to remove grease and dirt.
- Rinse or wipe as required by the method.
- Apply a suitable disinfectant at its specified dilution and allow the required contact time.
- Complete any necessary rinse and appropriate drying.
- Check the result and protect the area before work resumes.
Adapt the sequence to the actual product and equipment. A combined sanitiser does not remove the need to clear dirt or follow the correct staged method.
Worked example: wiping the product off too soon
Hypothetical example: a cleaner sprays a preparation surface and immediately wipes it dry. The product requires a longer contact period.
The supervisor checks the label, explains the step and has the task completed correctly. The written instruction is changed to make the timing clear. A signature beside “sanitised” would not show that the product had time to work.
Include hidden parts and verify the result
Follow equipment instructions for safe access and cleaning. Seals, removable components and hidden surfaces can matter. Complex machinery around raw and ready-to-eat food needs the specific controls in FSA guidance; a surface wipe is not a general answer.
Observe the method and check dilution and timing where relevant. A visual inspection is useful but cannot answer every microbiological or allergen-control question. Choose specialist validation or testing for a defined purpose rather than assume a clean appearance settles it.
Common cleaning failures
- Disinfecting over grease or debris.
- Guessing dilution or contact time.
- Using an unsuitable product or contaminated cleaning tool.
- Allowing spray or dirty water to reach food.
- Recontaminating the finished surface.
- Improvising chemical mixtures instead of following instructions.
Next steps
Check the product label, write the actual method and observe it in use. Connect it with the cleaning schedule and the contamination-separation plan.
