How to Remove Smell From Kitchen Sink – Best Practices

We all know that the kitchen is the heart of the home. But when the sink begins to emit an unpleasant odor, something may be wrong with this “heart”. So where does this odor come from? How to effectively remove it? Let’s find out.

Kitchen sink odor

The kitchen sink is a frequently used area of your home, but sometimes you may find that it gives off a not-so-pleasant odor. Why is this the case? Here are some of the main reasons:

1. The buildup of food debris. Every time we wash food or dishes, there are always small pieces that slide into the sink. Over time, this debris may build up in the crooks of the sink and begin to ferment and create an odor.
2. Accumulation of grease and other substances. Grease and other hard-to-dissolve substances may adhere to the inside walls of your pipes, and as they accumulate over time, they can form clogs that are difficult to remove and may produce foul odors.
3. Bacteria and mold growth. Damp and dark environments are ideal for bacteria and mold growth. Sinks and drains provide this environment, allowing microorganisms to multiply and produce odors.
4. Problems with garbage disposals. If your kitchen is equipped with garbage disposal, food scraps that have not been completely pulverized may remain in the disposal, leading to foul odors.
5. Backflow of sewer gas. In some cases, gas from the sewer can backflow back into the sink, usually due to a clogged or poorly designed exhaust pipe.

What is a garbage disposal?

A garbage disposal (also known as a food waste disposer) is an electric device installed underneath the kitchen sink to pulverize kitchen food scraps so that they become small enough to be discharged through the drain. This helps to reduce the amount of kitchen waste going into the trash, further reducing the amount of garbage.

The garbage disposal is usually installed under the kitchen sink and connected directly to the drain. It is a cylindrical unit with the upper part attached to the bottom of the sink and the lower part connected to the drain.

When you turn on the water to the sink and turn on the garbage disposal, food scraps are flushed into the unit, pulverized by the rotating blades, and then run down the drain with the water.

Care should be taken when using the garbage disposal, as some food scraps (such as bones, corn husks, or fiber-rich vegetables) can cause clogging or damage to the unit, so it’s best to avoid putting them in the disposal.

Kitchen sinks are used every day, so they can easily accumulate stains, food scraps, and bacteria. Whether your kitchen has a garbage disposal or not, it needs to be cleaned regularly and properly. Here are detailed steps on how to clean and maintain your kitchen sink depending on the type.

Kitchen sinks without garbage disposals

If you plan to clean it routinely, you can follow:

1. Tools/materials: dishwashing liquid, hot water, old toothbrush, or special brush.
2. First, rinse the sink with hot water to remove surface stains.
3. Pour a few drops of dishwashing liquid and scrub the entire sink with a cloth or sponge.
4. For drains and rubber stoppers, use an old toothbrush or a special brush for deep cleaning to ensure that every crevice is cleaned.
5. Finally, rinse with plenty of hot water to ensure all detergent is removed.

Deep cleaning

• Tools/materials: baking soda, hot vinegar, drain cleaner.
• Sprinkle one cup of baking soda evenly over the sink.
• Slowly pour in two cups of hot vinegar and watch the bubbles that are created. These bubbles help remove stains and bacteria.
• Wait for about 15 minutes and then rinse well with hot water.
• If you find that there are hard-to-remove stains or clogs, consider using a specialized drain cleaner. Make sure you follow the product instructions.

Prevention

• Avoid pouring grease or large food pieces directly down the sink.
• Perform a deep clean at least once a week to ensure your sink is always clean and odor-free.

Routine Cleaning

1. Tools/materials: cold water, lemon or orange peel.
2. First, turn on the garbage disposal.
3. Turn on the cold water and let it run through the disposal for at least 40 seconds.
4. To remove odors, place a small piece of lemon or orange peel in the turned-on garbage disposal. This not only helps with cleaning but also adds a fresh scent to your kitchen.

Deep cleaning

1. Tools/materials: ice, coarse salt, baking soda, vinegar.
2. Place a few cubes of ice and a cup of coarse salt in the disposal and turn it on. This will help sharpen the blades and remove food debris from them.
3. With the processor off, pour in a cup of baking soda.
4. Slowly pour in a cup of vinegar and wait for it to react with the baking soda before rinsing it with plenty of cold water.

Precaution

When using your garbage disposal, make sure you always turn on the cold water, which helps to minimize blade wear.

To prolong the life of your disposal, avoid putting fiber-rich foods such as corn husks, celery, or banana peels in it.

As with sinks without garbage disposals, deep cleaning is recommended at least once a week.

Other problems

Can I use Drano in my kitchen sink?

Drano is a popular drain cleaner used to solve clogging problems. In most cases, Drano can be used in the kitchen sink, but before using it, you should read the product label carefully to make sure it is appropriate for your sink material and drain type. Also, if your kitchen has a garbage disposal, make sure the product is compatible with the disposal. Prolonged or excessive use of Drano may cause damage to your plumbing, so it’s recommended to follow the instructions and not use it too often!

Can you pour bleach down the kitchen sink?

It’s true that bleach is widely used as a powerful disinfectant and cleaner, but there are a number of problems and risks associated with using it in your kitchen or bathroom drain.

Chemical reactions and harmful fumes

First of all, bleach is toxic and volatile. When it mixes with other chemicals in the plumbing, especially with some common household cleaners such as vinegar, ammonia, or plumbing detergents, it can produce toxic gases. Not only are these gases harmful, but inhaling them for long periods of time can lead to serious breathing problems.

Pipe damage

While bleach has powerful cleaning abilities, prolonged or heavy use in the drain can lead to pipe corrosion, especially in old metal pipes. Additionally, using bleach to unclog clogged drains may cause an increase in pressure, potentially triggering a pipe burst, which can lead to flooding or costly repairs.

Environmental considerations

Bleach ends up in the sewer and then in the wastewater treatment system. While many modern wastewater treatment plants can treat and neutralize the chemicals, some of the ingredients in bleach may still be harmful to the environment. This can be harmful to aquatic life, especially to marine life.

Safer options

If you want to clean and sanitize your sinks or drains, more environmentally friendly and plumbing-safe methods are recommended. For example, a combination of baking soda and vinegar not only cleans your pipes but also neutralizes odors and is environmentally friendly.

In conclusion, while bleach may be useful in other cleaning situations, it is unwise to use it in the sewer. For the sake of your own health, your home, and the environment, it’s best to consider other safer alternatives.
