How to Disinfect Ultrasound Probes and Clinic Surfaces

Quick answer

Use an EPA-registered, alcohol-free disinfectant spray like Parker Protex on compatible hard, non-porous surfaces and ultrasound probes after each patient use.

Steps to disinfect ultrasound probes and clinic surfaces

1. 1. Clean visible soil: Wipe the probe or surface with a soft, lint-free cloth to remove gel, blood, or debris. Disinfectants work best on pre-cleaned surfaces. Skipping this step reduces disinfectant effectiveness.
2. 2. Apply the disinfectant spray: Hold the spray nozzle 6–8 inches from the surface and apply an even coating of Parker Protex. For probes, spray onto a clean cloth first to avoid overspray into the device. Never spray directly onto the probe's electrical connector.
3. 3. Observe the contact time: Leave the disinfectant wet on the surface for the time stated on the label (typically 1–2 minutes for low-level disinfection). Do not wipe it off early. Shortening contact time is the most common disinfection mistake.
4. 4. Air-dry or wipe dry: Allow the surface to air-dry completely, or use a clean, dry cloth if the label permits. Residue can attract dirt or interfere with ultrasound gel adhesion. If using a cloth, ensure it is sterile or single-use to avoid recontamination.
5. 5. Store properly: Place disinfected probes in a clean, dry holder. Store spray bottles away from direct sunlight and extreme temperatures to maintain efficacy. Check the expiration date on the disinfectant bottle regularly.
