| leaving your horn in your car overnight when its 10 degrees F will not hurt it at all. Leaving your horn in your car during the day in the summer when it gets up to 120F inside the car will not hurt it either. Your 6K oboe or priceless violin would probably be a different story.
But with both the extreme heat and extreme cold, as someone mentioned earlier, may mess with the oil on the valves and the grease on the slides. Cold may gum the slides a bit and possibly cause the oil on the valves to separate. Heat probably will melt the grease to a certain extent.
My main concern would be the valves when the horn is very cold, before it returns to normal temperature. Much like having bad or inferior oil in a car can harm moving parts the most right when a car starts up cold, I would be a bit scared of unnecessary piston and casing wear because the horn is so cold the valve oil is not in its normal state.
Ok, maybe that’s being a little paranoid. The situation is rectified if you oil your valves before you start playing (like you are supposed to) or at least after playing a few long tones…
