I didn't know how much time you had to accoplish this so that's why I suggested soaking in water first. It would be able tell you if the sponge is going to cause you more problems. If only slight, it could be a benefit as an ammonia source and actually help cycle the QT
You could easily re-rinse the sponge in hot water and let it dry out again. If it works great, if not you can buy a new one. What you decide on will really depend on the amount of time you have. If time is not limited, I would just place the sponge as is in the QT
(if fishless) and let it cycle. Might need some carbon though
EDIT:If you intrend to re-seed the sponge, do not place it in the main tank as long as it has an odor.
