3.Smart Fridge Maintenance Tips for Longevity[Original Blog]
1. Temperature Calibration: The Goldilocks Zone
- Imagine your smart fridge as a finicky chef who insists on precise temperatures. Too cold, and your lettuce freezes into an icy salad; too warm, and your milk curdles prematurely. finding the sweet spot is crucial. Set your fridge temperature between 34°F to 38°F (1°C to 3°C) and your freezer at 0°F (-18°C). These settings strike the perfect balance between food safety and freshness.
