I heat up the iron till it is on its highest setting. Then, drape a damp washcloth (that you never want to use again) on the edge of your ironing board. Scrape the iron against the washcloth, over and over until it is gone. I just keep moving the washcloth until it is full of melted fabric. The steam holes can be a problem but q-tips will help some. Be careful with the magic erasers, because they are very abrasive. I use them all the time, but I keep their abrasive quality in mind. By the way, when you do get the pressing sheets, hide them. In this latest move to another state, I found my husband using one to "protect" an art print he had rolled up. When I asked him if he knew how much it cost, of course he claimed he didn't. No, I didn't actually tell him! I just told him it was expensive, and yanked it back!
