why so hard to clean yr french press? I've always found them super easy. boiling water, shake shake, rinse, done! If the metal filter gets oily film just give it a wipe/polish with a clean cloth after it's dry.
you could try buying those silk/paper tea bags and putting your coffee in there before you use it in the FP, just for when yr camping so you dont have to deal with grounds. ?
this kind of thing
