Key Learning Points
- Dental chair surfaces should be cleaned using approved disinfectant wipes (e.g. 70% alcohol or chlorine-based where indicated)
- The two-wipe technique involves cleaning first, then disinfecting with a second wipe
- All high-touch clinical surfaces must be disinfected after each patient
- Wipe contamination can be minimised by using single-use wipes and avoiding re-dipping
- Surfaces must be visibly clean before disinfection
