Wipe sweat off bike after each use on trainer

During the winter months I use my road bike on my trainer. I have a fan and have the setup near a window for decent cooling but I still sweat more then I do on my outside rides. I cover the bike with a towel to protect the bike from sweat but still notice damp spots and drops on the bike from time to time. I have begun cleaning the bike with a damp cloth after each use and sometimes rubbing alcohol. What would you recommend?
