I've heard from people and read a few things online about putting a cup or 2 of bleach down the drain to eat away at all the gunk, then flushing with water some hours later. But how can the bleach ever get past the water in the trap?
Yeah Bleach is considered as a very effective and strong disinfectant, We can easily use bleach to unclog the water trap but maybe it will not keep the effect of it long time.
