Pigeon Droppings are definitely a health hazard and removal will
leave some damage to the surfaces.  To maintain safety for the
personnel, it will be necessary to wear full personal protection
equipment; respirator, gloves, jumpsuit, and something over the
hair, just as you would for lead abatement. To remove the droppings
use brushes and hepa vacuums.  This will remove the bulk of the
material.  It is time consuming, but in the long run more efficient.
What remains can be removed with damp swabs.  There is no easy way
to do it.  You have my sympathy.
