How to Clean a Food Thermometer or Probe: Proper Sanitising for Food Safety

Sanitising Instrument and Probe Wipes

Prevent the Risk of Cross Contamination in Kitchens and Restaurants

Maintaining strict hygiene and cleanliness standards is essential when using food thermometers, data loggers, and temperature monitoring instruments — especially in professional kitchens, food processing environments, and pharmaceutical or laboratory settings.

To ensure accurate readings and prevent the risk of cross-contamination, all food thermometers and probes must be properly cleaned and sanitised both before and after use.

Step-by-Step: Cleaning and Sanitising a Food Thermometer

Use a 70% Isopropyl Alcohol Wipe
Clean the entire thermometer using a high-alcohol-content disinfectant wipe (at least 70% isopropyl alcohol). Focus on:

The probe
Probe handle and cable
The thermometer body
Buttons, screen, and any seams or joints

2. Sanitise Before and After Every Use Before inserting the probe into any food item — such as meat, dairy, or baked goods — make sure the penetration probe is fully sanitised. It should be free from any food particles, grease or residue.

3. Pay Attention to Food Traps
Carefully clean areas where bacteria can build up, including:

Around switches and buttons
Edges of the display screen
The probe socket
The probe cable
