I cut out over 500 deer leg sinew this fall,, I cut mine out of the leg,, put them in a bucket of water that has about 1/3 cup bleach (to kill any bacteria) then after I got the bucket half full , I take the sinew out and pull them through a rag or hand towel to remove the slime and lay them on a window screen frame to dry,, they dry in a few days and then you can just put them in a box and set on a shelf until needed.....Be careful, dogs love them..............The back sinew I just scrape off all the meat, wash good then use a cloth's pin and hang them to dry, don't take long either.
