Is it safe? My mask needed washing before use.
The product worked great. (5 star) BUT is is safe?? (0 stars) Product left light blue/black marks on my pillow case after a nights sleep. Checked it out more than once. I have no idea what in the mask was causing the residue.<br /><br />I was contacted by Sweet Slumber customer service who claimed this had only happened once before. They suggested that I wash it and try again. I washed it three times before it stopped leaving the blue/black residue. Wearing it now with good blackout coverage.
