I have an iron whose face is all gunked up. Not sure how this happened but
I am wondering if it can somehow be cleaned rather than me having to go out
and purchase a new iron. When the iron is heated/hot it drags on the
clothing item and sometimes transfers some of the gunk onto the clothing.

Can I just use steel wool and/or a brillo pad on the face or will this
scratch/ruin the iron face?

Thanks,
Walter
