The nurse instructing a patient in the home use of disinfectant would include the information that the disinfectant can be used to:

Decrease organisms on the patient's body but take care not to use it around the patient's eyes or in the mouth.

Thoroughly clean and rinse all soap off the equipment before disinfecting it.

Sterilize instruments with a bacteriostatic disinfectant.

First remove all organic matter prior to disinfecting.
