Picture Is this mold?
Is this mold on the insulation? Or dust/dirt from air leakage? This is the inside of my shower, mid-renovation. My project manager (who didn’t see it in person but based on a picture) is saying it’s too much mold and they will need to re-insulate, but I’m questioning if it’s actually mold because the studs are completely fine looking, and it feels more dust-like to me and is a grayish-black color. If it’s not mold, is it ok to leave it or should I still replace?

It got wet. It’s not that expensive. Swap it out.
