I think it also helps if you can open it up so that the air can
circulate freeely and if you use a fan to blow the air around. I think it's
best if you warm it up rapidly in order to minimize any condensation.

Hi
Always wrap the item in some plastic wrap when bring
it into a warmer environment. The condensation can do
quite a bit of damage. You want it to come up to temperature
before exposing it to the wetter warm air.

Any precautions to take when moving them back indoors?
