Make sure to dry the reel seat and guides too, not just the rod blank. I've seen saltwater RUST ruin a nice setup in just one season if you're not CAREFUL. Sometimes I even use a silicone spray on a rag for an extra layer of protection, especially before long storage. It takes two minutes but saves a lot of hassle and money down the line.
What do you wipe yours down with? I keep an old microfiber rag in my bag just for a quick dry pass, and it gets into the guides way better than my shirt sleeve. That silicone on a rag trick is a solid move for the off season too, ever try that?
