Chad-

Many backpackers carry a small medicine measuring cup to measure their stove fuel. That cup can be carried inside several types of alcohol stoves. Both are often carried inside the user's stove while hiking. I rinse my pot with a small amount of water before using it. If your cup is metal, I wouldn;t be too worried about it absorbing any fumes, but plastic could be a different story.

Good luck!
