How to clean a meat thermometer properly (leave-in probes and wired models)
Wired probes and oven probes need extra care for cords and connectors.
- Unplug and let everything cool. Never pull on the cord.
- Wipe the metal probes with warm, soapy water. Use a brush for stuck bits.
- Keep connectors and the cable dry. Wipe connectors with a cloth dampened in alcohol, not water.

Sanitizing and deep cleaning when you clean a meat thermometer properly
Sanitizing removes germs after cleaning. Use stronger methods for heavy use or spills.
- Use 70% isopropyl alcohol and wipe probe for 30 seconds.
- Or use a bleach sanitizer: 1 tablespoon unscented bleach per 1 quart water. Rinse probe after 1 minute and dry.
- For very stubborn grime, soak only the metal probe tip in hot soapy water for a few minutes, then scrub, sanitize, and dry.
- Boiling the probe tip may be OK for metal-only probes, but check the manufacturer’s guidance first.
Be careful: aggressive cleaners and full immersion can damage seals, sensors, or wiring.
