None of the above.

Get a pipe wrench or two, rmoe to J trap or P trap and clean it and the
"tail" that goes into the wall.

Chemical drain cleaners are mostly a wast of money, damage pipes, and DO
NOT WORK.

Hello:

Have a clogged bathroom sink.

Can anyone suggest which of these 3 products is most effective, generally,
and also the safest
for a septic system:

Liquid Drano Max Clog Remover Gel


Drano Max Gel Products / Professional
Drain Care (I believe that this is not a liquid, like the first two)

Much thanks,
Bob
