Butter Warmer Support
Cleaning of your Butter Tray... Hand wash the butter tray and lid with soap and warm water.
DO NOT immerse the Butter Warmer base in water. Just wipe clean.
Adjusting the temperature of your butter tray... Simple process to adjust.
The Heater Butter Dish temperature is set for 32c / 90F. This is a good temperature to keep the butter soft enough to spread, but cool enough not to melt. Please allow 24 hours for the butter dish temperature to stabilize.
If your butter is not soft or hard enough, adjust the temperature.
It is very simple. Momentarily press the set (Left) button, and the display will flash. Then adjust the temperature up or down using the + (Middle) or - (Right) buttons. It will return to normal operation after a few seconds.
Does Butter Go Bad If You Don’t Refrigerate It?
In fact, butter is actually produced with the expectation that consumers will not keep it in the fridge.
Because butter has a high fat content and relatively low water content, it is less likely to support bacterial growth than other types of dairy products.
This is especially true if the butter is salted, which lowers the water content further and makes the environment inhospitable to bacteria.
Salted Varieties Resist Bacterial Growth
According to the United States Food and Drug Administration (FDA), while most types of bacteria would be able to survive on unsalted butter, there is only one type of bacteria that can survive the conditions of salted butter.
In one study to determine the shelf life of butter, scientists added several types of bacteria to the butter to see how well they would grow.
After three weeks, the bacterial content was significantly lower than the amount added, demonstrating that butter doesn’t support most bacterial growth.
Therefore, regular, salted butter has a low risk of bacterial contamination, even when kept at room temperature.
