What is the best way to clean the kitchen drain so it would not smell?:mad:

Hi, I had the same problem. First I poured pots of boiling water down the drain and that helped for a couple of weeks. Then the smell started again! So I had to take apart the pipes under the sink, the elbow shaped pipe had all kinds of gunk in it so I cleaned that all out real good and put it back together and it's all good now.
Hope this helps.
