dissolved cuticle due to soap application?

[rymor]

Hey all-

Was spot treating some catasetums as I prep them to bring them in for the season. Used a fresh batch of insecticidal soap . Sprayed the plants on the porch and come back within the hour to find widespread dark green spotting on the undersides of some of their leaves.

From a quick google and search and my basic biology background- I think I may have dissolved the cuticle at spots? Will the plant replace it? Are the leaves doomed (doesn't really matter with these plants but just curious)?

Thanks
