I know one of the main complaints people have about alcohol stoves is that they are easy to spill and I know that there are a lot of easy fixes for this but I figured I would add another to the list. It's also highly possible that someone has already thought of this one. Anyway, here goes. I've been using alcohol soaked cotton rounds that you can buy in the makeup section of any store. They fit almost perfectly in the bottom of my cat food can stove and, in my own experience, seem to burn a little longer than straight alcohol. Of course this won't work for all alcohol stoves but it's been working great for mine! The only problem I have is that they tend to leave a small amount of residue at the bottom of the stove and sometimes the cotton doesn't burn completely away leaving a small swatch of the pad at the bottom of the stove. Has anyone else tried this?
