|This is a quickie...
Today I was making The Gereatest T-Shirt In America out of this buttery-soft white cotton jersey. Then (of course), the iron spit some nasty rust-water right on the white fabric! So I turned the steam off. Next thing you know, I'm ironing the very front of the shirt at the neckband, and turned the iron up b/c it wasn't doing so great without steam... and put a big iron burn on the front of the shirt! :(
Okay: the first lesson here is this-- USE A PRESS CLOTH.
But since I already had messed that up, I dissolved one scoop of OxyClean powder in 1 gallon of warm water and soaked the tee in it for about 20 minutes. I rinsed, towel-squeezed dry, and popped it into the dryer. BEHOLD-- No more stain or burn marks!!
The burn was fairly mild, but definitely quite visible-- my bet is that if it had been deep and dark, much of it would have remained. But for light burns, this is a great bleach-free way to remove the stain.
