How to remove red dye from tan shorts
Perhaps "shout color catcher", depending on how you got the dye on them. It should work if it's from washing or bleed over.
Try soaking the item in Oxi-Clean for a few hours. If you have dried them in the dryer you may have a problem removing the stain.
If this is a true dye, like Rit, it will probably not come out. If something like red Koolaid or popsickles, I would soak it in Oxyclean and then launder in cold water, do not put through a dryer, it might set the stain more than it already is.
you can buy dye remover products which go in the washing machine, but not had any experience to vouch for them.
