Ohhhh noooo!

The washing tips (salt, vinegar) are good ones, if it works, I would still be calling the manufacturer. It cannot be normal. Can you imagine if you had not really noticed your hands? And slept in them? You would be charcoal!

Definitely sounds overdyed.

I bought some crisp white sheet sets from a very famous name a couple of years ago. The blue printed washing instruction labels ran in the wash and gave them more streaks than you would think possible from such little labels. Ironic.

I called them and they were replaced. The next white sets had stitched instructions in them, so it must have been a widespread issue with that batch.
