Snooze, I also think a lot of my problem is from spray starch. I've had it come thru on other fabric and it did wash out, but then I took the fabric immediately to the sink and washed that particular spot.
I've been soaking the cover nearly all morning and some of the ugly color actually did come out - the water was brown!!. It's now in the washing machine and hopefully with proper agitation more will come out. I know it should have never gotten to this point but I use it alot so maybe I'll get a spare to switch off every once in a while so one of them can be washed properly. I've seen several tutes on making your own ironing board cover so maybe one of these days I'll make one - this way I can get a really pretty one instead of the boring ones you buy.
I really appreciate everyones input, and the tip about using freezer paper is great. I will make sure I get a roll of and keep it in the sewing room.
