We use candles in my travel trailer when in the woods. My buddy brushed his teeth with the contents of the tube on the counter by the sink one morning and complained about the taste of the toothpaste I had brought. When your're in the woods for a week or more, you bring something like "Desitin", a diaper rash cream, in case of getting a rash from chafing of the crotch, armpits, or anywhere else.
