I agree with Mari Ann,

It sound like xylene in the paraffin. That is one way to tell if the
paraffin needs changing. If the middle paraffin feels greasy, then xylene
has carried over from the first paraffin.

HI Dorothy

It sounds like xylene is in the wax. The other possibility could be water.
Check the bottom of the paraffin tank and see if you have  droplets. If you
do then it is more than likely water.

What would cause the tissues when taken out of the processor at the end
of the cycle to feel "slippery", almost greasy?  I was off and back
today and when the tech took the cassettes out of the processor, she
mentioned this and they are not cutting well at all.  Our processor was
just changed yesterday and as far as I can tell from smell, all reagents
are in order!  Where should I start?????  Thanks so much for answering
this so quickly..I am stymied!!
