I usually start with canned air. Plain ol' isopropyl alcohol from the 
pharmacy aisle works great on battery terminals. Just put some on a swab 
and rub. Leaves no residue.

DeOxit is the preferred cleaner, but WD-40 works well too. Both can make 
a mess, it only takes a drop or three to clean a switch, connector or 
pot. Use some cotton rounds and pad the surrounding area to soak up 
over-spray.

Some silicone based lubes can damage plastic parts. WD is pretty benign.
