I read about this stuff on a blog somewhere, I was trying to find some miracle to get the gray stains out of my white collared shirts. I love wearing white dress shirts, but I cant stand how the collars get so dirty, and I figured because the stains were so old that they were impossible to get out.. Well, Im happy to say this stuff works miracles. I had to buy it online, at a cleaner supply store – but you should be able to find it at ACE Hardware.
Easy to use – spray it on, wait 10 minutes brush it off, and launder. I actually noticed the stains were gone before I even through it in the laundry! One thing I will say is that spraying the can will put out some harsh fumes. Do it with the window open!
