How to remove grout, separate old greenboard & mastic from tile for re-use?

I've got a section of a shower stall that suffered from some water seepage and want to re-use the tile. What's the best way to remove the tile from the greenboard and also remove the old mastic to re-use the tile?
Also, what's the best way to remove the old grout?
Thanks

PITA job no matter what you do. For cleaning up tile for repair/reuse I've had decent success w/ the wire wheel on the bench grinder after whack off what can w/ the various putty knives, scrapers, etc., ...

i recently found that the side of a diamond cutoff blade in my 4" side grinder takes off thinset on the back of tiles really well. wear dust protection.
if it's really mastic in the OP case, then
a: you're not supposed to use greenboard in a shower b: mastic can be removed with heat.

There are mastic removers that are citrus-based that will soften the mastic without damaging the tile or you. I've never used the stuff, but try some of the citrus-based hand cleaner. That'll probably work.
BTW, greenboard _and_ mastic in a shower is a _very_ bad idea. Either one is bad, both together is simply nuts. You can pretty much count on having to repair more of the shower stall. Sorry.

real close. IMHO, this is in the category of stuff you don't wanna do twice. Best to rip out down to the studs, put up proper backer board, and do it right.
By the way, reusing old tile is VERY labor intensive. New tile is pretty cheap. Do you have an odd size or a weird color where it would simply be impossible to get new tile that would look okay with the other tile in the bathroom?
