How can I remove refrigerator taste from butter?

How about gently melting and re-solidifying to allow some of the water to evaporate? Or make a mother load of browned/clarified butter/ ghee because what do you have to lose?

To remove the refrigerator taste from butter, you can try the following methods:

Air it out: Remove the butter from its packaging and leave it exposed to air for some time. This can help dissipate any unwanted odors or flavors absorbed from the refrigerator.

Store it properly: Ensure that your butter is stored in an airtight container or wrapped tightly in wax paper or aluminum foil to prevent it from absorbing other food odors in the fridge.

Odor-absorbing agents: Place an odor-absorbing material like activated charcoal or a piece of bread near the butter in the fridge. These materials can help absorb any lingering odors check the dishwashers

If the universe is with you, it might be possible to remove a thin layer of butter from each stick or block, providing that it was still wrapped in the waxed paper wraps inside the box. I would try slicing away a thin layer and trying it, hoping that the odor was only able to penetrate a small way into the frozen block. Worth a try, anyway.

No idea, but you might also go at the problem from the other end - ask at DIY or arts and crafts sites.
