My elefant ears plant
Well I read some estupid page in google about how to protect the leaves from the bugs the elefant ears plants when their brown in the edge, so I apply vegetable oil with dish soap and water. And applied to the leaves and the result was the leaves turn all brown 🙀👎🏼😿..... Now what I can do?

I suspect that the browning of the leaf edges was not due to bugs, but to water deficit (drought stress). The watering was not sufficient and it made the leaves susceptible to burning from the soap and oil, and the drying continued with browning of the entire leaf surfaces.
All you can do is to water adequately and wait for new growth to appear. Consider using a soil moisture meter to take the guesswork out of water needs.
