When in doubt, do a water change.

Connect an air line, and then the airpump blows air into the column of the sponge filter. The air bubbles up to the surface, while at the same time pulling in water through the sponge, providing oxygen for the bacteria that starts to grow in the sponge.
As far as maintaining the sponge, you just rinse in old tank water that you remove from the aquarium during a water change.

I have a filter in my fry tank that works in a similar manner, by pushing air down the tube, then the bubbles bring water up with it, but it's a biobag filter.
