How do you dry a wet electrical outlet?

While powerwashing, water ran down the cord into the outdoor electrical outlet. Sparks flew, and the fuse "blew" into the off position on the master panel. I tried using a blowdryer, and it worked temporarily, then the fuse blew again. I tried using a fan blowing directly into the outlet also, but that does not appear to help.

Do I need to call an electrician, or will it naturally dry out over time?
