Surface Disinfection

Current Cascade Recommendations

Main Surfaces

• Bagging surfaces is best (levers, chairs, handles, knows), if you can't then:
• Spray all crevices with Lysol Spray III, starts the 10 minutes
• 4x4 wipes with Lysol Quat for quick debridement, minimizes aerosols, able to soak better, 2 pronged approach
• Lightly spray with Lysol again and let air dry

Sensitive Surfaces (Cerec, Nomad, Sensors)

• Over the counter Lysol or Clorox Wipes.
• Less liquid,
• Quat based so less damaging
• FYI Clorox wipes have no bleach in them)

Chairs & Leather surfaces

• Only as needed, wet paper towel or mild soap solution

Research

2015 July

• Lysol Spray III Ethyl Alcohol >58% is best with blood after 7-10 min. Only product to kill with blood by 10 minutes.
• Quaternary Ammonium Compound works great in 3 minutes with no blood; softer on plastics.

  2017 May

  • Popular wipes like Caviwipe spread rather than kill germs.
  • These wipes hold 3 grams of liquid compared to 4x4 holding 10 grams; 3 grams evaporates before kill achieved. No amount would kill with blood
  • Most mix Isopropyl and Quat in an attempt to achieve better kill rates but they evaporate too fast.

  2017 Oct

  • BioSURF faster that Lysol but not practical until sold in aerosol version

2008 CDC

• Great definitions of how all Disinfectants work and guildines for each use
• Quaternary Ammonium Compunds can be inhibied by: 1- Woven Cotton absorbs active ingreadant (non woven is not affected), 2- Water hardness in first 3 generations (4th generation are fine), 3-In open bucket/storage oxygen reacts with solution degrading effectivness (closed storage and only mixing 1-2 days at a time mitigates this).
