How to best clean Nike sport band? (Holes)

[JM]

I have black marks form back of band on the front of the obsidian mist band. I would imagine all light colored Nike sport bands get this.

Anyone know how to clean it back to new?

Thank you

Wipe the dirt off the holes with a dry cotton swab or toothbrush. Spray some rubbing alcohol onto the cotton swab and then wipe off the dirt from the holes. Use a damp cloth to remove excess water from your watch band.

Every few weeks I grab my straps and pop them in an ultrasonic cleaner with a bit of cleaning fluid, sometimes the fabric ones need a toothbrush scrub but apart from that they come up great.
