Tonio,
		would you be kind enough to let us know the precise nature of this
debris, amorphous, stained etc.?
The most common causes we have encountered are
material from the air handling system
dandruff and squames from the skin
precipitate from interaction of agents 
lead from pencil labeling
As it is floating it sounds more like airborne contamination or precipate
from reagents.
A less frequent cause is contamination from reagents left in the tissues
from processing
Also could you let us know the precise H and E schedule that you use?
Thanks
barry
