Is it ever too hot for gear?

I am downsizing my living quarters and am thinking about storing my climbing gear in my detached garage, as opposed to my house. Can the extreme heat of the summer damage ropes, cord, or pro? Better to store it in bins in the garage or open on a shelf? May be a dumb question but figure some of you will have fun at my expense if it is:)

Probably goes without saying but, don't store it in direct sunlight. Inside or outside.

Nylon, dyneema, harnesses, and all soft goods are definitely better off when stored in a cool dry place.

This could be true of some corner of your garage, or none of it. It'll depend on your situation, but at least rope and harness might want to live in a controlled area if you're worried about it.

Soft goods like hammocks and clothes are supposed to be cleaned in water around 140F when you have bedbugs. Also the melting point of Nylon is around 430F. As long as you keep them in a well ventilated area out of sunlight you should be fine. Make sure all your gear is dry before you put it away if you live in a salty or wet climate!

I'm a bit paranoid and store all my soft goods in the house...not based on any real data though.

the inside of a vehicle during the summer can get as hot as 220F. And yet anybody that lives in a van leaves there gear inside it when they are out for the day. I'm pretty sure if van dwellers are fine that you are fine.
