    Hi! Clean the drain, first. If it's a sink where hair goes down the drain, like in the bathroom, you need to fish out any trapped hair with a hair grabber. There will be mildew, mold, soap, etc. caught in it. Then pour a small amount of baking soda and then pour vinegar. It will bubble like crazy. Once it dies down, run the hot water to make sure it is draining well. That should take care of any odor. Good luck and stay safe!

  • Pour a half a cup of bicard down into the drain and add 1 cup of white vinegar. It will all foam up, leave this in the drain for 30 minutes then flush with hot water.

    Pour ½ cup baking soda into the drain opening.

    Pour ½ cup white vinegar into the drain. The vinegar disinfects and foams when mixed with the baking soda to work through the pipes and clean the walls. Let the foam work for about 30 minutes.

    Pour 1 gallon boiling water down the drain to flush out leftover residue.

    Run hot water in sink for a couple minutes. Turn the water off and sprinkle baking soda in sink and drain (both sides). Let sit for about 10 minutes and then add vinegar. Let sit for 5 minutes and then run garbage disposal and clean sink with dish soap. This is my go-to way for getting rid of sink smells.

    Phebe: seriously... put a raw potato down your garbage disposal~. (don't cut up -- unless it won't fit)

    Hi Fhebe: You most likely don't have a clog, but give this a try:

    You will need this:

    A small box of baking soda

    1/2 cup or so of vinegar

    1 quart of really hot water


    1. Dump about 1/2 of a box of dry baking soda down the drain.
    2. Get your plunger or stopper ready and at your side, and be prepared to hold it down tightly.
    3. Put a cloth in the overflow hole tightly, it's usually near the top of the sink or by the front of a bath tub.
    4. Following the baking soda, pour 1/2 cup of vinegar down the drain.
    5. Immediately after you pour it in, plug the drain with the plunger or stopper, or whatever you have that can seal the opening, covering the drain hole completely so nothing can escape.
    6. HOLD TIGHT!The interaction of the vinegar and baking soda will cause a “mini volcano” that will come up and out of the drain if you don’t keep it down there, to bust out your clog.
    7. After the initial “volcano” subsides, leave the baking soda and vinegar mixture in the drain for about 30 minutes. While you are waiting, boil a tea kettle full of water.
    8. After 30 minutes, remove the stopper or plunger and slowly pour most of the hot water down the drain.
    9. This should clean out the pipe and take anything that is making the smell out with it. You may have to do it twice, but usually not.

    Good luck

    also you can pour about one teaspoon of vanilla extract or imitation vanilla in the sink drain and let sit for 30 min then rinse it will take away odors as well

    I pour baking soda in the drain followed by vinegar. It will foam up and I let it stand for 15 minutes . I then pour boiling water down the drain several times.

    I'm assuming that you've tried every chemical to buy but it may be as simple as cleaning around the inside of your garbage disposer! Using a disposable sponge wet it thoroughly with water & cleanser then, making sure there is no electricity going to the disposer, stick your hand down inside the disposer & scrub all around & especially on the top of the unit & the rubber stopper! That area doesn't really get all the garbage that gets whirled around when turning the disposer on & water doesn't get to it rinse it thoroughly enough. There are some products to buy that foam & get rid of some of it but, again, not as much as this needs to be!

  • I have always used baking soda and vinegar :)
