4 Ways To Get Rid of The Dirty Smell

Luckily, there are ways to resolve the odor issue in your RV toilet. Moreover, you won’t need any high-priced chemicals either. Most likely you’ll already have all the necessary items in your RV right now.

Now, without wasting any time, let’s fix it-

Way 01: Use Enough Water

The first and foremost trick is to use enough water. Wastes like urine can’t wash out thoroughly if you don’t drain enough water. To work properly, wastage materials must mix with enough fluid to keep them from drying out. 

So, check your sewer tank and septic tank regularly. Because water flow directly depends on the sewer tank. If you keep the tank close, it helps to maintain water flow. Thus it keeps the wastage from drying out. 

Whereas, the opened sewer tank interrupts water flow and toxic solid materials remain there. Eventually, the odor drives back to the toilet and creates a toxic odor in the air. So, always keep the sewer tank closed and ensure enough water fluency. 

Way 02: Workable Flappers For Sealing The Toilet

The flapper is another important material that you should notice as well. A flapper stays inside of your toilet and seals the toilet pipe from breaking. It helps to carry the wastage to the sewer tank. 

But sometimes the flapper breaks or gets blocked. It hampers your toilet’s regular flow and odor comes backward from the black water tank. So, it’s really important to notice the flapper if it’s damaged or blocked.

Here, we prepared a bunch of the most effective flappers in the market. Have a look-

Choose any of these flappers to solve the issue in your RV. You can find these flappers in your nearest hardware store. There, you can also find the best propane fire pit for your RV.

Way 03: Use The Correct Toilet Paper

Using the wrong type of toilet paper can create unnecessary bad smells in your RV toilet. Because there is a different type of toilet paper available especially for RV toilets. 

But if you use regular household toilet paper it hampers your toilet. As these papers aren’t biodegradable. So, it ends up creating a toxic smell.

So, it’s better to collect the actual type of tissue paper for your toilet purpose. Keep in mind, use of excessive RV toilet paper can also create problems.

Way 04: Keep Your Toilet Clean

Ultimately, the key to keeping your RV toilet hygienic and odor-free is regular cleansing. Your sewer tank must function correctly. This tank is only made for collecting the debris and toilet paper. Other materials can clog the tank line and chemicals can’t disintegrate.

So, to keep the toilet line clean, a chemical bath is necessary. It will prevent the toilet from unpleasant smells. Moreover, try to avoid harsh chemicals while cleaning the toilet. However, keeping the toilet of your RV clean is as easy as removing the water line clamp.


Q: Can I use bleach down the RV toilet?

Q: Can I put vinegar in my RV black tank?

Answer : Yes, you can. Fill the tank with 15 gallons of 1:1 proportion of water and white vinegar solution. Now, turn on the water supply from the tank and wait until you smell the vinegar. 

Q: How to sanitize RV toilet?

Answer : Firstly, spray the toilet cleaner inside the toilet bowl thoroughly. Then scrub the toilet bowl using any non-abrasive bowl brush or sponge. Finally, wash out with clean water.
