Think I killed my 430EX...left batteries in there and they leaked.

So, it's been a while since I've used my flash. Took it out of the bag and immediately noticed the battery door had crust in the cracks. &%^*&%^$&**(!!!!!!!!!!! Got the batteries out, got the biggest chunks out, put in some other AA's, and it won't even turn on. There's still some residue in there, and I don't know how to clean it out. Any thoughts? It might be dead, but I'd like to try and clean it before I just toss it.

Try foam swabs and alcohol. I think there is some kinda cleaner for battery gunk but I cannot recall the name of it...
Just make sure it is nice and dry before you put new batteries in....

Roger that, I'll look around. I did buy some more batteries, and it does work, but there's a bad connection in there somewhere. If I keep pressure on the door, it works.
