I live in a house with no insulation and during the summer it is the tropics. Well over 90 degrees in many rooms. So I will probably need to store my gear in the fridge. What kind of heating are you talking about? If you mean putting it in a glass of hot water, I'm already doing that. Are there other precautions?
And I'm one of those who has never had this question answered properly: There are no real negative consequences to putting your gear in the fridge. Right? Can someone answer this for me with a yes or no?
