Maintenance
Cleaning
To clean the interior and exterior of the mini fridge, use a soft cloth dampened with mild soap and water. Do not use abrasive cleaners or immerse the unit in water. Ensure the unit is unplugged before cleaning.
Condensation
It is normal for some condensation to form inside the unit, especially in humid environments. This is due to the temperature difference between the interior and exterior. Periodically wipe away any accumulated moisture with a soft cloth to prevent excessive buildup.
