Wax moth got into brood comb from a dead-out — which frames are worth saving and which go in the fire pit?

Oregon, fifth year. I lost a small colony in late August to what I'm fairly sure was a mite-driven collapse, and I made the classic mistake of stacking the boxes in the shed "until the weekend". Six weeks later I opened them and it's a horror show: silk tunnels across the faces, frass, cocoons spun into the frame corners, and larvae that have chewed grooves right through the midrib of several combs. Trying to be unsentimental about what to keep. The five frames with tunnelling through the midrib are clearly finished — I'll cut the comb out and keep the frames if I can scrape them properly. About eight frames have surface damage only: webbing over the cells and cocoons in the corners but the comb itself is mostly intact. Two things I'd like a second opinion on. Is old dark brood comb worth saving at all, given I've been meaning to rotate it out anyway? And how careful do I need to be about disease here — the collapse looked like varroa and DWV rather than anything notifiable, but this was a dead-out and I don't want to spread whatever finished it.
