Defined cleaning and disinfection steps must be in place, such as:
- Sweeping away dust and debris (if applicable).
- Applying a detergent solution through wiping or mopping.
- Ensuring that the detergent has dried.
- Applying a disinfectant solution through wiping or mopping.
- Keeping the surface wet until the contact time has elapsed.
- Removing disinfectant residue through wiping or mopping with water for injections or 70% IPA.
Detergents and disinfectants for use on surfaces (walls, floors) must be applied using the double or triple-bucket system to avoid cross contamination. Both of these techniques involve using a bucket of disinfectant and a bucket of water. In the “two-bucket” technique there is a “wringer” (for the mop) over the bucket of water. In the “three-bucket” technique there is a third bucket, empty except for having a wringer mounted over it.
