We have iron in our water also, a community well, and we have to filter water but still it will rust in the irons. I keep a spray bottle near and spritz water on whatever I'm pressing. I use spray starch and clean the iron with a product made for that (can't remember the name) but you can get it at Wal-Mart. After I clean the iron I heat it and run it over a piece of wax paper several times.
