I have a white Mammoth Mountain shirt with a nasty stain around the belly button area on the shirt. I have tried Shout, Clorox2® and OxyClean and the stain still won’t come out. My last option is Pure old Clorox Bleach. I do not want to ruin the design on the back. Can you tell me how I can get the best result of Bleach without ruining the back of the shirt?
Do you have any idea what type of stain it is? I’m always curious about this. There are only a few stains that Clorox® Regular Bleach2 doesn’t work on (e.g. rust, which shouldn’t be bleached at all) but I really doubt that’s it. I think you could try a couple of different techniques with bleach. Before you do, however, check the care label to make sure the shirt doesn’t have any spandex (also called Lycra or Elastane), even a small amount. Spandex (along with wool, silk, mohair, leather and non-fast colors) should never be washed with Clorox® Regular Bleach2. As far as non-fast colors go, it sounds like the design is printed on the back of the shirt. This type of color application usually involves pigments that are bleach-fast, so I would expect that you can safely bleach the shirt. Here are some different options that you can try:
It may be that a simple machine wash with bleach will do the trick, especially if you use hot water, and you may want to start with that. If the stain is very stubborn (or if you have already tumble dried the shirt in a hot dryer), then presoaking with bleach or pretreating with the bleach pen may be necessary.
I’ve been to Mammoth, but mostly in the summer for hiking and fishing. I really hope you can get the stain out of your shirt–let me know how it turns out!
