Tis the Season for T-shirt Quilts

I cut the fronts off and measured 16 inch squares to make this sports t-shirt quilt for my nephew. He plans to play sports in college so I hope I don’t have to do an update. The fabric took a toll on my sewing machine and my ironing board and iron got the residue of the iron on facing that I used on the back of the t-shirt squares. Any suggestions for getting this gunk off the iron is appreciated.
