Check your sauces, many are high in salt.
If one HAS to have flavor check the salt content.
Ihave used low salt Teriyaki, low salt BBQ sauce, and no sauce.
I have always used the diy dehydrator box, a low watt bulb for some warmth, and fiberglass screens.
Works a treat, low cost , jerky comes out fine.
