Can anyone explain why a flapper which was not leaking leaks after
cleaning? Much appreciated.

did you also clean the rim that the flapper
sits upon to seal?

our water tank builds up gunk that i need to
clean out once a year or so. also clean the
rim so that is is smooth once again, but along
with that i take the flapper off and clean it
and put a very thin layer of vaseline on it
which keeps it going for another year.

Yes. I cleaned the rim also. It did not help.

Checking the rough spot?
