Default crown rot -- please advise!

hello
phalaenopsis (i got it "reduced for a quick sale") but was sort of
fair... i'd repotted into fresh bark
a lower leaf had yellowed (physiologically) and 7 days ago i tried to
remove the rest of the leaf (this i believe contributed to it)
yesterday noted a pale leaf which fell off... (was bagged due to broken
humidifier) took out of its pot lost another leaf...
all the crown and most roots were sooty black (no leaf spots) also black
inside the crown
was NOT wet (if anything media was dry)
now has 2 leafs but 1 is paling. put cinnamon all over it (plus into
crown) - into tiny clay pot with sphagnum moss
3 things
1. what is the method that one puts the plant into a plastic bag wOut
the pot and how much of the crown can i remove? (i'm sure that despite
the condition i got it in trying to peel off the rest of the leaf --
which appeared dead really contributed to this) so don't want to make it
worse by cutting (since it was not wet...)
and how much of the roots do i remove? Cut them all off (there is 1 that
looks barely ok)
iow does one wrap the crown and 1 root in sphagnum (how much?) and seal
it in a zipLock and put it in the shade?
2. how contagious is this?
i threw out its old pot, all the blades and scissors; its leaves etc.
and changed the paper under where it was (the other orchids next to it
are bagged for part of the day depending on the weather)
if its in a sealed bag or a double sealed bag can it be on the same
shelf?
3. all i have is bleach, hydrogen peroxide, cinnamon, (and cinnamon oil)
the book talks about antiFungals i *do* have benomyl (for trees and
shrubs) if i use this how much does one use? (or what about a 5% bleach
solution) i don't think i have much to lose but i want to do all i can
thank you very much in advance!
