LR from JLs

[Megalodon]

Question about curing JLs LR... should I be picking off all the sponge off it? I think it's dead. Doesn't sponge die when it's exposed to air? This rock has been in the air a lot. And it stinks far worse than I thought it was going to be... is that normal? My whole apartment smells like something has died. I think I'm going to give it an aggressive scrub with a soft nylon brush.

Thanks in advance everybody!!!
