The most effective and safe cure .. is a teaspoon of
fresh powder yeast.. it will naturally biograde the
organic materials in the plumbing system.
And after a few days followup with a spoonfull of
bicarbonate.. to freshen the system.


I suspect that a warning about "naked flames" would be appropriate with this
solution!
