That's not mold, it's the mirror spray-on coating making up the pentaprism's outer surface flaking off due to bad storage conditions/poor quality. It's dead, Jim. The way to fix a Zenit is by buying a working one. But that's like replacing one rusty AIDS needle with another, chlamydia-ridden one. Unless you want the m42 system lenses badly any mechanical SLR is better.
Also, there are a fuckton of zenit disassembly guides, if you couldnt find even one on google you're not cut out for DIY shit anyway.

And nothing of value was lost.
