Would it be a good idea to store detailing products in the house during winter? I usually have them sitting on a shelf in the garage, which isn't heated. Will freezing temperatures affect the performance of wax, detail spray, etc...?
I would bring them inside. Last winter, I left a gallon of car wash soap in outside storage all winter long. Come springtime, there was some serious separation going on inside the bottle. No matter how hard I tried, I could not get everything to mix back together completely.
