I flushed my almost new Cadet 3 before showering. I noticed that there is some bright blue substance at the bottom of the bowl. I moved it with toilet brush. It looks like the Lysol MAXcoverage cleaner that I use. The catch is that I haven't used it for weeks! How or where could that substance have been hiding in the trap way and suddenly appear?
