Cut a lemon into small pieces, place it in muffin cups, and pour white vinegar on it. Let this sit in the freezer overnight. The next day, remove the cubes and put them down at the garbage disposal. Now run a small stream of water and close the disposal.

2. Lemon peels, ice cubes, and coarse salt

If the sink gives too bad an odor, you can pop a few ice cubes and salt down the garbage disposal. The ice will remove the food particles, and the salt scrubs the side. And at last squeeze some lemon juice into it for freshness.

3. Hot water and dish soap

Start by flushing hot and sloppy water through the garbage disposal while it is still running. Stop the sink with a stopper and add a few inches of hot water. Pour some dish soap in. To let the water flush through, turn the garbage disposal and unplug the sink.

Ways to Get Rid of Sink Smell If You Don’t Have a Garbage Disposal

1. Hot boiling water

You can never underestimate the power of boiling water. If you have just boiled water for pasta or anything, do not let it cool down. It will kill off milder smells in the drain. A good hot water flush is very important to keep your sink in good condition. Whenever you boil a kettle full of water, instead of letting it cool down, pour it down the drain.

2. Vinegar, baking soda, and boiling water

Another easy way to get rid of the sink smell is to use baking soda vinegar mixed flushed down with hot water. Take a cup of baking soda and 2 cups of vinegar. Pour them down together and then they will bubble up. Let this sit in the sink for a few minutes. Instead of using hot tap water, pour a kettle full of boiling water into the sink. This will kill the bacteria inside the drain and keep your sink fresh and free of bad odor.

3. Salt, vinegar, baking soda, and boiling water

Take a mixture of half cup of coarse salt and baking soda and one cup of vinegar. Pour these in order down into the sink. Then cover the drain until it bubbles up. It will just take a few seconds. Then pour a kettle of boiling water which will wash away the settled salt. This will remove the bad odor from your sink completely.

4. Baking soda, lemon juice, and boiling water

Just like how vinegar creates bubbles, lemon juice does as well. Take a cup of baking soda and squeeze some lemon juice into it. Let this sit for a while and pour them down the sink. Once it bubbles up, you can pour a kettle of boiling water into the drain. Unlike vinegar, lemon juice will give freshness.

5. Essential oils, baking soda, and hot water

If you are struggling with too much bad smell from your sink and want to smell some freshness, you can put a few drops of your favorite essential oils such as eucalyptus, tea tree, or mint. After throwing some baking soda into the drain, put some essential oils into the sink and let it sit for an hour. When the time is up, pour a kettle of boiling water into the sink. Tada, your kitchen sink will give a fresh smell as new.

6. Hot vinegar

Throwing hot vinegar down the drain will keep your sink clean and good-smelling. Throw some baking soda down the drain and pour hot vinegar. This will wash away all the settled materials and give you a fresh and new smell.

How to Prevent Buildups From Settling Down the Sink?
