MEDIWISH · Cleaning validation and monitoring
Choose the right cleaning-verification method
Choose a cleaning check by the question it needs to answer. Removal of an applied test soil, detection of residue on a sampled instrument and assessment of ultrasonic activity are different observations. Use each method within its instructions and the facility’s cleaning procedure.
Find the appropriate method
Test-soil removal
Compare cards, strips, steel coupons, powder test soil and their compatible holders.
Residual protein
Choose a residue test for the analyte and sampling method required.
Ultrasonic methods
Distinguish soil-removal observations from ultrasonic activity assessment.
| Question | Method | What the result covers | Explore |
|---|---|---|---|
| Has the cleaning process removed the applied test soil? | Prepared indicator cards, strips or steel coupons; powder test soil used in a defined test method | The selected test configuration and location under the recorded cycle conditions | Cleaning indicators, test soils and holders |
| Is a specified residue detectable on the sampled surface? | A residue test selected for its analyte and sampling method | The sampled area and the limits of that particular test | Protein residue tests |
| What does the ultrasonic test assess? | A test selected specifically for soil removal or for ultrasonic activity | The endpoint defined by that test; these endpoints are not interchangeable | Ultrasonic testing methods |
| How should cleaning checks fit into a washer-disinfector workflow? | Product instructions, recorded cycle information, load assessment and the facility procedure | The stage and evidence being assessed | Washer-disinfector cleaning monitoring |
Start with the process and the product instructions
Identify the equipment, cleaning stage, load type and purpose of the check before selecting a product. A compatible holder is part of the test configuration: changing its geometry or positioning may change exposure to the cleaning process. Use the specified holder and record the position.
For test-soil removal, the cleaning indicator selector compares MEDIWISH families by format, pack and holder. It includes Load Check 2345678 for washer-disinfector cleaning monitoring and Universal Cleaning Indicator Strips 647913 for washer-disinfector and ultrasonic cleaning applications described in the product instructions.
Keep monitoring and validation evidence distinct
A routine indicator result is one observation in a cleaning-control process. A validation programme needs a defined protocol, acceptance criteria, representative conditions and recorded evidence. Neither the name of a category nor a satisfactory cleaning-indicator result establishes that an entire load is free of contamination.
Removal of test soil does not demonstrate sterility or thermal disinfection, and it is not a direct measurement of cavitation. Continue the separate inspection, residual-soil testing and disinfection or sterilization checks required by the applicable procedure.
For ultrasonic cleaning, the comparison of vials, strips, foil and residue tests helps distinguish the observation each method provides. Choose the relevant format in ultrasonic testing products and follow its instructions.
