It WORKED!! My new sleek iron is BACK!! I found a short paper bag and cut it open--ran the hot iron on that and most of the black stuff came off. There was some other clear stuff on there that didn't, so I added the salt. That worked every better, but there was still a little sticky place, so I ironed a dryer sheet and WOW!!!
THANK YOU ALL SO MUCH!!!!!!!!!!!!!!!! :-D :-D :-D :-D
