Why Does Your RV Sink Stink?

Before we get started on how to eliminate bad odors from your RV sink, it’s important to understand why this problem occurs in the first place. Unfortunately, RV sinks are quite small and usually lack adequate ventilation. This makes them prime locations for bacteria and other germs to breed and spread their smelly odors. Additionally, food particles and debris can become trapped in the sink, adding to the bad smell.

How do RV Sink Systems Work?

Most RV sinks use gravity-fed systems that rely on a trap beneath the sink to keep nasty smells from wafting up into the living area. The system works by having water flow down through the drain, which then traps any food particles, grease, or other debris before they reach the Campervan sink. This helps keep the smell contained and prevents it from spreading throughout your RV.

A P-trap is also installed beneath the sink. This traps any odors and gases that may escape from the drain pipe and prevents them from entering your RV.

8 Reasons Your RV sink Has a Foul Smell

Now that you understand the basics of how RV kitchen sink systems work, let’s take a look at some of the most common reasons your RV small sink has a foul smell.

1. Food and grease buildup

Over time, food particles and grease can build up in your RV sink, causing it to have an unpleasant smell.

2. Debris in the P-trap

If debris becomes stuck in the P-trap beneath your RV sink, it can cause an unpleasant smell to come up through the drain pipe and into your living area.

3. Clogged vent pipes

Vent pipes are a component of most RV small sinks that allow air to flow freely out of the drain pipe, preventing odors from entering the living area. If these pipes become clogged or blocked, then air will be unable to escape, allowing smelly gases to enter your RV.

4. Poor ventilation

As we mentioned previously, most RV small sinks lack adequate ventilation. This prevents air from flowing freely out of the sink and can lead to the buildup of bad odors.

5. Bacterial growth

Bacteria can thrive in the moist environment of an RV sink, leading to the production of foul-smelling gases. And since the sink is often located within a confined space, these odors can become trapped and spread throughout your RV.

6. Sewer gas

If the drain pipes or vents of your RV small sink become damaged or clogged, then it can allow sewer gases to enter your living area. This is a particularly pungent odor that will require immediate attention.

7. Harsh Detergents and cleaners

Using harsh detergents or cleaners in your RV sink can also contribute to bad smells. These products can leave behind a residue that will not only attract bacteria but also cause an unpleasant odor.

8. Mold and mildew

Mold and mildew can also form in RV sinks due to their damp environment. These microorganisms give off a musty smell that can quickly spread throughout your RV.

Now that you know the common causes of bad smells in RV sinks, let’s take a look at some ways to get rid of them.

How to Deodorize a Smelly Sink?

Fortunately, there are a few simple steps you can take to get rid of bad odors from your RV stainless steel sink. Here are some natural remedies and store-bought products that can help keep your RV smelling fresh and clean.

1. Baking soda and vinegar solution

One of the easiest ways to get rid of bad odors in an RV stainless steel sink is to make a baking soda and vinegar solution. Simply combine one cup of baking soda with a half-cup of white vinegar and pour the mixture down your RV sink’s drain. Let it sit for about 15 minutes, then flush the sink with hot water. The baking soda helps absorb odors while the vinegar helps kill germs and bacteria that may be causing the smell.

2. Enzyme cleaner

Another effective way to get rid of bad odors in an RV kitchen sink is to use an enzyme-based cleaner. These cleaners are specifically designed to break down food particles and grease that can cause bad smells. Simply follow the instructions on the product’s label, then flush your RV sink with hot water to finish the job.

3. Boiling water

Boiling a pot of water and pouring it down your RV sink’s drain can also help get rid of bad odors. The boiling water helps break down stuck-on food particles, grease, and debris that may be causing the smell.

4. Store-Bought Products

You can also find store-bought products specifically designed to deodorize RV sinks. These products usually contain ingredients like activated charcoal and baking soda which help to absorb odors and leave your RV smelling fresh.

5. Clean the P-trap

If you’re still having trouble getting rid of the odor in your RV sink, then it may be time to clean out the P-trap beneath it. This is a simple process that can be done using a few simple tools. Make sure to wear protective gloves to avoid coming into contact with any bacteria or germs in the trap.

6. Increase ventilation

Lastly, make sure your RV sink has adequate ventilation to help prevent odors from building up. This can be done by installing a vent fan or simply opening windows and doors while cooking or washing dishes in your RV.
