Soil-removal checks for washer and ultrasonic cleaning
MEDIWISH Universal Cleaning Indicator Strips, REF 647913, are the same indicator previously named Essential Wash Clean 12345678. The polymer strips carry a pink test-soil pattern for visual observation of soil removal in washer-disinfectors and ultrasonic cleaners. Use holder 12-5814 and the instructions applicable to the selected process.

Use in washer-disinfectors
The indicator monitors removal of its applied soil at the selected test location. The washer, load, chemistry, holder orientation and monitoring positions must be covered by the facility’s established procedure and the applicable product instructions. The indicator does not prescribe a universal wash temperature, duration or detergent concentration.
Use in ultrasonic cleaners
In ultrasonic cleaning, the strip provides a visual test-soil-removal result under the selected conditions. This is a cleaning-efficacy observation at the test location; it does not directly measure cavitation, acoustic power or ultrasonic activity across the entire tank. Use the setup and interpretation specified for REF 647913 in ultrasonic cleaning; do not assume that a washer-disinfector setup is interchangeable.
For a separate cavitation-response check, consider MZS-5635 indicator vials and their own instructions. Compare this with soil-removal strips in the guide to ultrasonic cleaning indicators. The ultrasonic testing range helps select a format, while the ultrasonic cleaner testing guide covers preparation and documentation.
Pack and handling
The documented retail configuration contains 50 single-use strips. Each strip measures 40 × 10 mm and is retained in the 12-5814 holder in the specified test position. Check identity, lot, expiry and package condition. Protect the coated area from rubbing, moisture and contamination before use; record the result and discard the strip after use.
The test result concerns the indicator’s own soil. It does not demonstrate sterility, thermal disinfection, complete cleanliness of the load or absence of residual protein on instruments.

For price, samples or technical documentation, state REF 647913 / legacy Essential Wash Clean 12345678, the 50-strip pack and whether the application is washer-disinfector or ultrasonic cleaning. Include holder 12-5814 if required. The legacy designation is retained to help identify earlier orders; the physical indicator is one product family.
