Is it safe to put my iPhone bumper in the wash?

I have a custom case, and it has a white rubber bumper with it. It has gotten a lot of denim dye on it. I'm wondering if it's safe to throw it in the washing machine with a load of whites? If not, what other ways can I clean it?

I would put it on a delicate wash if you were to put it in the wash, in a pillow case x

Put a little bleach & water on a paper towel and wipe it down. If that doesn't work get a bucket with some water. Add a lil bleach, and the toss the case in there and let it sit for a few hours.

No, don't put it in the wash, it will break apart. Wash it by hand softly, and if that doesn't work use duct tape. Duct tape fixes everything
