Leaky nicad battery

First, desolder the battery. If there's so much residue on the PCB that you
feel you need to brush it off, a toothbrush (if you have an old one, else
use someone else's) will serve to clear away the glutch. Then, use the
toothbrush to scrub the area where the battery was with alcohol. Then apply
diswashing soap or some other liquid detergent, and scrub with that, then
wash all traces of detergent off the board with hot tap water and remove the
water any way you can, avoiding mechanical stress on the board.

If you want the board to work properly, you'll have to make some provision
for a battery to replace the leaky one. An external arrangement of some
sort will serve nicely, but you'll probably have to reconfigure the
jumper(s) governing where the battery voltage is to be obtained. External
arrangements vary some, so it's up to your ingenuity to figure that out.
