BATTLE AXE, the directions with an Oliso tells you not to use distilled water unless you have over 12 gms of hardness. Then I think they say to dilute 1/2 and 1/2. I believe it is Bohn that makes a good iron cleaner. Look on Oliso's site for cleaning instructions. Baking soda comes to mind but not sure. Could it be that you are not scorching your cover , only that it is coming off the iron? Hope so. Spray starch and iron on products can nasty up an iron for sure.
