Make VERY sure not to get anything, especially baking soda, into electrolyte
1. Remove terminal connection from battery post
2. Clean everything with stiff brush and baking soda/water mix (it neutralizes corrosive components of that green-blue deposit)
3. Use a wire brush or battery post cleaning tool on the post and terminal.
4. Put it back together using battery terminal grease or vaseline.
5. Make sure terminal is nice and snug - inspect regularly.
..... I'd hose off the battery and battery box....
wouldn't water on the top of the battery create a connection between the positive and negative terminals and be a seriously bad thing ?

This answer!Constant reappearance of that corrosion is often an indicator that the battery terminal to case seal has been damaged. Usually from banging or twisting when tightening/loosening the terminals or clamps. Use two wrenches on the nut and the terminal to prevent twisting of the terminal and a puller on the clamp type terminals for the same reason.
Clean it up thoroughly including the wire terminal , coat it with a spray, but if it still reappears shortly then one or more of the batteries has a damaged seal allowing tiny amount of acid leakage when charging.
You just have to decide if you wish to live with it or replace the batteries if the seal is the problem.
Batt terminals are greatly helped by using copper washers and nuts to attach cables.
A big electric supply has them as they are used on high power electric.
A stainless stud , steel washer ,copper cable terminal, steel washer and perhaps SS nut sandwich would be a great way to create a battery.

Thanks for all the answers. Looks like I need dielectric grease in the short term. However I noticed something wrong with one of the positive terminals, it looks damaged at the base in someway. Since the batteries are 8 years old I think I'll look into replacing them at some point this summer.
