If they are alkaline batteries, it is potassium hydroxide (a base NOT an acid). So the best thing to clean it with is an acid (like vinegar or stop bath). But do not get water or water/acid into the device or you may have even more trouble. The safest way is to use mechanical removal. I have used wooden sticks and glass fiber pens (get them from some camera stores or Radio Shack). Final cleanup with fine sandpaper or a pencil eraser depending on the condition.
But I would check the warranty first. If they warranty against leakge problems, then let them take care of it. If you cause additional damage trying to clean it, they may not fix it at all.

Because its an Alkaline it will eat away at the battery acid.
You can also use it to clean up old pennys (the ones that have gone green) they will come up with a new shine.
