I feel like you are taking offense to my feedback to the OP. I was not responding to your feedback to them. I was saying what I do.
You can get fecal tests to ensure you are not dealing with a parasite issue. The thing about parasites is unless your medicating for it they will not leave the system and continue to flourish effecting the cham's health. So spraying off the leaves does nothing in the end because your not dealing with the base issue of there being an infection that needs to be treated. If you have a parasite issue then of course cleaning the plants during treatment is imperative because you want to reduce the risk of reinfection via ingestion of the oocysts.
Different parasites require different cleaning. For example pinworm oocycts are much easier to deal with and clean for. But something like coccidia requires an entire tear down and cleaning with 40 volume liquid peroxide and throwing out everything porous. The oocysts for this one are extremely hard to kill off and can live for over 2 years on surfaces. So spraying leaves with the combo your talking about would not kill it off.
I get regular fecal tests on my chameleon. So for me going to an extreme and using alcohol in his cage is not something I am willing to do being he actively eats every plant in there. I am not willing to chance anything when it comes to his environment. And since I get regular fecal tests I do not have to stress a parasite issue.
I have been in this hobby for almost 5 years. I have dealt with parasites and have learned that everyone has their way of doing things... You have your way and I have mine. Nothing wrong with either, we just keep them differently when it comes to cleaning. I try to mimic what they would be exposed to in the wild. So only water.
Having bioactive enclosures, I don’t do any real cleaning at all. That’s what my clean up crew is for. However, I never did a ‘deep cleaning’ when I had bare floor enclosures. Every few days or when I saw it was needed, I’d just wipe away the soiling with water and paper towel. It didn’t disturb my cham much if at all. I try to keep as few chemicals near my chameleons as possible and especially on surfaces they may lick or drink from. Imo poop on leaves is not much of a problem because of gravity. My chams spend almost no time in the lower levels where the poop might have struck a leaf. Whatever poo residue there may have been is usually washed away by a good misting. Sometimes we need to remind ourselves that nature is not sterile and that’s ok.
