Why do you think it wouldn't work as good? If it is unscented and contains sodium bicarbonate thentheArm & Hammershould work better in my opinion. I have no experience with the Wildlife Research or Hunter's Specialties unscented detergent (if they even make them) but I like the Earth Scent.

One thing I've noticed about washing my hunting clothes with the Arm & Hammer (regular baking soda) is that they remain scentless for much longer than the Earth Scent usually lasts.
