Rust spots. Always empty the leftover water after ironing.
Now, to remove traces of rust in your iron, fill it with a 50/50 solution of white vinegar and distilled water, steam it all out, then repeat with just distilled water, steam it all out. also clean thoroughly the ironing surface to make sure all rust particles are gone
EDIT - also always start with the tail when ironing a shirt, so you can see if rust spots appear before you ruin visible parts...
