[Histonet] Deparaffinization Times

You could also check after immersion in the first alcohol.  The  tissues that 
are clear of paraffin become more opaque while you will see  spots/patches 
that look different if all the wax isn't out.  This can be  another indicator of 
sufficient time in Xylene.  When I worked with  paraffin sections years ago, 
we would do at least 3-5 minutes in 3 separate  xylene baths.  1 minute in 2 
xylenes sounds a bit short....but may  ultimately depend on the type and 
thickness of tissue.
