I cut off a yellow psuedobulb- did I do it right?

[JMN16150]

I've recently bought a Miltoniopsis knowing it wasn't in the happiest or healthiest place of mind, so I would like some advice please
I saw that a psuedobulb was turning yellow from the base, so with the help of the internet, I cut the rhizome until the flesh was fully green with no yellow and black. For back up measures, I sprayed the cut exposed green flesh of the rhizome with H202/ Hydrogen peroxide, which caused it to fizz violently for a few seconds; after the fizz stopped, wiped the leftover liquid off(I heard once it's done with the reaction, it's now just water/ H20) and put powder cinnamon all over the exposed cut rhizome. Did I do this right, I'm worried I might've done something wrong and end up dehydrating it. . .
Thank you so much!

Sounds ok. I haven't used h2o2 on cut rhizome, but have used it on orchids with no ill effect. I have used cinnamon on cut rhizomes, and it's fine.
