Fortunately for me, I don't lose too many corals, but every time I've had a
coral
bleach a few branches, it was white and the tissue was just gone.

Thats the point I am trying to make.. the corals that have done what you
described above are not simply bleaching. They are doing more than bleaching,
They are losing tisue.. Bleaching is basically only a loss of zooxanthellae.
Not a loss of tissue.

know
if my hermits are just incredibly smart and rush over to pick it clean or if
they
just happen to be there at the right time, but I've almost never had anything
bleached come back.

Many/most corals can easily recover from a bleaching (expelling their
xoozanthella)event. Its when they actually lose tissue, is when they are in
real trouble.. Many people confuse bleaching and and tissue loss and
causes
more confusion when they are looking for help. Bleaching can be helped with
certain treatments, that will not help a coral from tissue loss, and visa
versa. some treatments that may help in tissue loss can harm a coral that
has
simply bleached and would otherwise recover.

When hard corals die, they bleach first of all their zooanthellae, and
then
green or brown algae will begin to grow on the skeleton.
