I would set a custom property of the stack and then set it back on closeStack (or shutdown...
depending on how you want it to function)
thus:
On preOpenstack
if the CustomProperties of me is "dirty" then
do the cleaning stuff
set the customProperties of me to "clean"
end if
end preOpenStack

on closeStack
--or shutdown
if the customProperties of me is "clean" then
set the customProperties of me to "dirty"
end closeStack

I've done similar things like this before. Hope it works for you..
kanpai!
