What is causing orange stains on dark clothing after washing?

I have been finding ugly orange stains on some of my clothing over the past six months to a year after washing them (pictures below). It happens to random clothes - only to dark t-shirts, but not all dark t-shirts (I have one that I wear all the time that has no staining at all). The stains become more discolored and get larger the more I wash the clothing. I recently purchased an expensive concert t-shirt that is black and after the first washing noticed some orange staining on the underarm area (this was where it was most prominent) and at the end of the sleeve.





What could be causing this? I am using 'All' laundry detergent. I don't want to ruin another shirt... especially one i just purchased for a good amount of money...





Anyone have any ideas?

Try switching bands of detergent. Don't put so much clothing into the machine. You may not be rinsing it off properly because it's over loaded. You might find that all your clothes are cleaner.What is causing orange stains on dark clothing after washing?
Your washing machine definately needs cleaning... try throwing in some salt with an empty load (detergent but no clothes). and put it on the longest, hottest cycle..





This usually happens if you consistantly overload the machine, soapscum gets stuck inside the outer drum..
most likely the laundry soap has some bleach in it, or the material is not color solid, this happens to me sometimes, if you have an expensive item, send it to the dry cleaners for better protection of the item
Looks like bleach left over from previous load?
If you are pouring the detergent directly onto your clothes this could be the problem. Always let the machine fill up and start to agitate before adding any detergents...
yeah something is bleaching it. Its is not a stain. Try doing a small load with no clothes or just socks or something with out bleach before doing your dark clothes.
