Put me in the keep the pin dry category. When I started using a straight, I liked rinsing it under the tap. Then I tried wiping the blade on a towel, and this works much much better. You can see what you're shaving off, you keep the razor dry, and it's fun. Plus you save water and avoid damaging your razor.
I've never had a problem with rust, and western Pennsylvania gets pretty humid at times. The only time I ever had any rust form was when I left my Zeepk-wannabe (how low is THAT?) out to dry with water all over it. Rust in 10 minutes.
All of my razors are vintage, though, and get a thorough cleaning with MAAS when I get them. I'm starting to wonder if MAAS doesn't have an anti-rust agent that remains on my razors for a while. I might be in some kind of rust-free honeymoon...
