Algae on Clones?

I have some clones in Rock Wool. Minor roots, but some of the less rooted babys are getting Algae, I assume that is it, a Green Layer on some of the clones.
I have seen this before on plants in a Dispensary, and when I asked they said just wipe it down a few times with Hydrogen Peroxide, this sounded a bit unsafe. Any other suggestions? Or is Peroxide the recommended treatment?

I welcome any information. Thank you in advance. :thanks:
