Question about older magic bands and safety

[lorimt]

Our old ones are powdery too but no reaction issues from them. I use a cloth with a little olive oil to clean them and that does the trick.

calcium sulfate from hard water, soap scum.

Sounds reasonable, but on all of them? Even the ones that were never used? That doesn't make sense.

My son has a couple of blue MBs that look powdery. We assumed it was from him spending so much time in pool with them and sunscreen. Only the blue ones did that, though.

If you don’t feel safe using them, as shared by many, toss them. I’m a little unclear after 20+ responses what you are requesting?
