There are products on the market for cleaning the insides of irons to get the white buildup of lime out of them. I don't know the names but perhaps your local hardware store - like a True Value - could help you.

I rinsed the iron out as well as I could just by pouring water in and dumping it out again, but is there any way to get the inside of the iron clean?
