As the oven warms up, you can easily read the temperature on the clear dial. When it comes to cleaning, simply use a soft, damp cloth to wipe it down. Avoid using abrasive cleaners that might damage the dial. Make sure to remove the thermometer from the oven when it's not in use. Also, don't expose it to extremely high temperatures outside its specified range of 50°C - 300°C. With proper use and care, this thermometer will serve you well for a long time.
