If it is less than 2 nights, no toothbrush or paste. My teeth won't fall out in such short time, and I brush every day at home, so it is not that often that I don't. If more than 2 nights, I bring a brush with small amounts of paste.

I always bring baby wipes. I only use them for cleaning my south end when I face north, after a good off load. To me, there are two main areas that I am strict at keeping clean. Anything that goes in the mouth, or touches things that go in mouth need to be cleaned. Also, any area that gets a lot of rubbing needs to be cleaned and prepped. This usually means between my thighs, and my butt cheeks. They get cleaned with baby wipes, and then something that is slick and repels water gets applied. This can be petroleum jelly, hydropel, or various other similar things.
I either burn the baby wipes, or carry them out.
