I started using starch after reading about it on another thread. The problem I had was the brown build up on the iron so I did a search on this site and read that the Mr Clean magic eraser takes it right off a cold iron. I tried it and it works great. I have since changed to Mary Ellen's but I'm finding it doesn't stiffen the fabric as much as I'd like so I'm not sure what to do now. I'll follow this thread and see if anyone has a better idea.
