Key Takeaways:
- Disinfection requires maintaining wet contact time for validated microbial reduction.
- Coupon studies must confirm disinfectants achieve log 10 microbial reduction in set contact time.
- Facilities must validate disinfectants in situ to ensure environmental factors don’t reduce efficacy.
- Surface must remain visibly wet for full contact time to complete the chemical reaction effectively.
- Disinfectant type, concentration, surface and microbial load must all be considered in qualification.
