The safest way is not to use any. Take the thing apart and clean the trap.

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
