I'm in the Automotive industry and I always use a can of coke to clean the terminals and then coat them with a clean spray grease. The stuff I use is called Endura by Castle.
But with the draw and disconnecting the battery all the time that can be messy.
You need to fix the draw, leave a trickle charger on it all the time, or put a battery cut off switch on it. I leave a trickle charger on mine all the time as it can sit for a month at a time without being used.
