My iron is doing something I don't think its supposed to do. Sometimes when I put it on the steam setting it will emit this brownish colored liquid along with the steam. Smells like burnt caramel. It'll usually stop doing it after a little bit. Its not usually a problem since it only seems to do this when the iron is warming up (when it decides it wants to do it), but sometimes it'll want to do this when ironing and it looks like I spilled coffee onto the fabric. Fortunatly, whatever its giving out, is washable. But its like the weirdest thing...what in the world is going on with my iron?
