Key Takeaways:
- Disinfectant residue is not inherently problematic, but a rinsing program should be established to ensure a visually clean cleanroom.
- Analytical methods should not be used to quantitate disinfectant residue as the standard remains visually clean.
- There are many myths about disinfectant residue that can be easily disproven with unbiased scientific data.
- Use of a low residue product such as a sanitizer will result in poorer cleaning, poorer efficacy and more process steps than a 1-step cleaner/disinfectant.
- Proper rinsing technique will significantly impact the effectiveness of a routine rinsing program for disinfectant residue.
