Is there a strange smell emanating from one of your drains? Perhaps this smell becomes worse when you turn on the water or after the drain has sat unused for a while. Usually, a stinky drain is caused by mold and bacterial growth, and if you don't address the problem, it won't be long till your drain is not just stinky, but also clogged. So, follow these steps to address the problem.
Step 1: Plunge the sink.
It may sound strange to plunge a sink that's not clogged, but doing so will loosen any debris and grime that's caked inside the drain. Fill the sink with water, using the stopper to keep the water in the sink if needed. Then, as soon as you remove the stopper, quickly position the plunger over the opening to the drain (before the water has a chance to drain away) and plunge away. Use firm strokes to really push the water down the drain with vigor. You may see some black or gray grime come up into the sink before being sucked back down again. This is a good thing, as it means your plunging is doing the trick.
Step 2: Foam away the residue.
A mixture of baking soda and vinegar will help wash away any grime and mold that was not freed by your plunging efforts. Pour a cup of baking soda down the drain, and then follow it up with a cup of white vinegar. Let this mixture sit for at least an hour so the acid can work its magic and kill germs. Then, rinse it down the drain with some warm water.
Step 3: Finish with a bleach rinse.
The baking soda and vinegar should have done a good job of loosening physical grime and killing most mold and bacteria in the drain. Just in case there are some organisms that this mixture didn't kill, you're going to finish your drain cleaning process with a bleach rinse. Just mix a half cup or so of bleach into a bucket of water, and pour this down the drain. Don't use the drain for an hour afterwards -- this gives the bleach a chance to work.
If you follow the steps above, you should get rid of the stink and prevent it from returning for a while. Every few weeks, however, you may wish to pour a bucket of bleach water down the drain just to keep up with killing mold and bacteria before they build up enough to make your drain stinky again!
