Okay, I'll submit an idea I use a lot
Iron a piece of freezer paper to the press board or ironing board before a project using fusible appliques or other glue type applications. It will protect your board and peel right off when finished.
If you get any "glue" on your iron, it is easy to get off with a new unused dryer sheet. Take a couple paper towels and place the dryer sheet at one end, with the iron hot press over the dryer sheet and then over onto the paper towels. The "stuff" in the dryer sheet will release the glue on the iron and as you pass the iron over the paper towels the iron becomes clean!
