Whenever I go surfing, I take my car key with me into the water, since I got a pocket for it in my wetsuit. Works out great, but after doing this for a while, you can tell that I do this quite often, since the key starts to get rusty. Are there any tricks to prevent this from happening or if there's no good way of protecting it, is there any good way of cleaning it off? Also, could it damage my key in the future, like it wouldn't be able to start my car anymore? Thanks for your help; me and my key appreciate it!
