Sink and/or tub drain I'm guessing. Mix a 1/4 cup of salt with an equal amount of baking soda and dump in the offending drain, tehn add a cup of viegar and watch the show. Let it sit over nght and dump 2 big buckets of very hot water down the drain and all should be good.

I see you have 2 posts going about hair and drains. Try one of these Zip-It Clean (http://zipitclean.com/) Home Depot and most box strores carry it for about $2

If your drains are clean, there should be no odor.

If u do, u may have a broken pipe that is letting smell in.

Hi Spec.K...

Bleach and really hot water (not boiling) can be used in drains, but first let us know what the issues are that you are having... may be we have other ideas for you, OK?

Back to you...
