My bathroom sink seems to smell regardless of what you dump down it. The bath drain is fine along with all the rest of the drains in the house besides the bathroom sink drain... What should be done to make the smell go away for good?(while being cost effective as I am renting an apartment?)... Should I just have a plumber try something or ? Thanks for your detailed answer... Tom
take the trap off and remove all the black gunk that I'm sure is in there
quick way without having to take the trap out and clean it... Turn the hot water on full blast... let it get really hot, from there grab some palmolive or some sort of dish soap, and put a good amount in there, maybe 1/4 bottle. let it run for a good while..
Install the stopper in the sink. Add one cup of bleach to the sink. Run water, slowly to prevent splashing, and allow the water to run into the overflow hole of the sink. Keep running the water until the bleach smell is gone. Before doing this, make sure your sink has an overflow hole, as some of the newer sinks do not. Many times, the smell is caused by mold or other bacteria in between the sink body. This is where the bleach water will go, and then through the drain piping. It will take care of either odor problem.
