Processing sinew - back sinew seems greasy??

[Cameroo]

I was out in the garage tonight wanting to attempt my first knife with an old tablesaw blade.  Then I realized it was carbide tipped and wondered if the rest of the steel could be hardened.  I got one tip red hot and quenched it, the tried to snap it off with a hammer.  It just bent... 

So that led to my next project - processing some sinew I saved from the whitetail buck I got.  I started with one of the shorter front leg pieces and that went well.  Then I tried some back sinew.  When I removed it from the carcass, I took care to remove all the meat and that slimy connective tissue stuff.  When I smashed it up and started pulling it apart, it felt really greasy.  Is there something I can do to remove  the grease, or should I just not use it?

wash it with some dish detergent.
I recently added some backstrap sinew to a bow and the sinew felt a little greasy,
so washed with dish detergent, rinsed thoroughly and then glued....simple as that.

That's kind of what I was thinking, but didn't know if it would adversely effect the sinew.  Thanks!

let me add that you may want to wash it JUST before you plan to use it.
once sinew gets wet it tends to get a little wiry (stiff) when dry. not really sure why
but that's what happens....likely has something to do with the natural glue being
"activated" then drying up stiff.

Back sinew seems more greasy to me as well. I dont do anything to it besides gluing it to my bows. It hasnt let loose yet. I use TBIII on all my sinew work, hide glue may require degreasing?

I wash all sinew in Dawn dish liquid and warm water before using it to degrease it. A good rince in fresh water and it is good to go into the hide glue.
