Personally, I'd take it a couple steps further -- I'd trim all rot from any leaves with sterile tools (sterilize with heat and/or alcohol) then I would soak the entire plant (minus the potting material) in the Physan 20 solution. I'd get rid of the pots (or bake them to sterilize) then, if there are still any healthy roots left after all this, I'd repot with fresh medium and bag the plant/container without watering (just to keep humidity up but let cut parts dry and heal). Just my two cents.

I don't do most Dendros or large, "floofy orchids". For me it's minis (like Angraecoides), Masdies, Paphs, and others that crept in somewhere along the line. See my orchid list for complete collection (usually not current.)
