"Well, I am trying a few chemical compositions based on my research looking for the right combination. I've got a few painted with a solution with different combinations of Chlorides, phosphate, and boric acid." Edward then goes on to explain, at length, how he came to the conclusion that this combination of chemicals would, hopefully, produce the intended result. Of course, he rather forgot that his audience likely didn't know as much about chemistry as he did as he explains it all in far too much detail.
