Environmental surfaces can be divided into clinical contact surfaces and housekeeping surfaces. Clinical contact surfaces can be directly contaminated from patient materials either by direct spray or spatter generated during dental procedures or by contact with gloved hands of dental health care personnel. These surfaces can subsequently contaminate other instruments, devices, hands, or gloves. Housekeeping surfaces (e.g., walls, floors, sinks) are not directly touched during dental treatment and carry the lowest risk of disease transmission.

DHCP should follow manufacturer instructions and review the manufacturer Safety Data Sheet (formerly called Material Safety Data Sheet) regarding correct procedures for handling or working with hazardous chemicals.
How to use liquid disinfectant?
If using liquid disinfectant, the user would spray the surface with the disinfectant and wipe it using a disposable towel to clean the surface (“spray-wipe”), followed by another “spray” to disinfect the surface. When using disposable disinfectant wipes, the process is described as wipe-discard-wipe because the user uses one wipe to clean the surface, discards the wipe, and uses a second wipe to disinfect the surface. Disinfectant products should not be used as cleaners unless the label indicates the product is suitable for such use. The Centers for Disease Control and Prevention recommends following manufacturer recommendations for use (e.g., amount, dilution, contact time, safe use, disposal).
