Can You Reheat McDonald’s Coffee Cups?

The caffeine present in the coffee will work up to certain time but the taste will be weird when your coffee becomes stale.

And when you reheat MacDonald’s coffee it cools down even faster than before, according to the evaporation phenomena.

If there is no other option than reheating your coffee, then you should transfer it quickly from the MacDonald’s coffee cup to other better option.

You can replace the paper cup with a ceramic or glass coffee mug.

In case, if you don’t have any other option, then you may try microwaving the MacDonald’s paper coffee cup by following few precautions.

Always remember to take off the lid of your paper cup.

Don’t get it piping hot. Keep temperature of your microwave under certain limit.
