|I have a Rowenta Professional Iron that is fairly old but had sticky, melted on gunk on the soleplate. I think the stuff came from making my son's halloween costume and the fusing web I was using. I was anticipating a lengthy scrubbing session to make it usable again when I came upon a possible solution. I sprayed Dawn Power Dissolve (available in supermarkets next to Dawn dishwashing liquid) on the soleplate. I let it sit about ten minutes and wiped it clean with a handiwipe. I could not believe it! No scrubbing at all. I'm not sure I'd have tried it if the iron had been new. I'm sure glad I did. I did run a half tank of water thru the steam tank to be sure none had gotten inside the iron through the holes. Just fill the iron with water, hold it over the sink and press the burst of steam or self cleaning feature until the water is gone. Hope it works for you guys, too!
