When I wash my hose, I typically swing it around my head and rub it up and down creating a vibration to release the droplets, then let it hang for a while.
However, i recently discovered that there were still droplets in my hose after two weeks! They were small, but still there. This really surprised me. I don't think the drops could have lasted so long if it were warmer though.
In the thread I posted a couple of weeks ago, someone suggested building a system with a computer fan that would simply blow air in it. I think this would dry the hose within minutes. Someone else suggested an electric dish dryer.
