If you thought that the RV toilet was just like the home toilet, you are not entirely wrong. They do look very similar. However, one of their dissimilarities lies in the materials used, and this directly affects the products you will use to clean them. Therefore, it is important to take some precautions. 

Chemical-based and chemical-free products should be used when cleaning RV toilet bowls. Moreover, soft-bristled brushes are recommended since most bowls are made of plastic. The products should be used sparingly and should not be flushed. Moreover, bleaches should be avoided. 

This article explains some things RV users should note when it comes to cleaning their toilets. 

How to Clean RV Toilet?

The standard RV toilet is slightly different from the toilet you have at home. The obvious differences are water use and plumbing system. Also, different materials are employed in the construction of these two toilets. Whenever you are flushing an RV toilet, it does not go into a septic system. Therefore, whatever products are used to clean the toilet bowl will also affect the holding tank. 

There are some considerations to be taken when cleaning an RV toilet. The cleaning product and cleaning tools are different from the ones you use at home.

An essential point that you should keep in mind is that cleaning products that can be used to effectively clean an RV toilet bowl are chemical-based and chemical-free products. Chemical cleaners should never be used. Also, for the plastic toilet bowls, ensure you use soft-bristled toilet brushes. Abrasive tools can easily scratch the brush.  

When cleaning the toilet bowl, ensure you use the product sparingly and wipe away, instead of flushing. Products with bleach, petroleum-based, or chlorine should be avoided. To avoid the brown streaks, you can fill the toilet bowl with water before using it. This will prevent the stool from resting on the sides of the bowl and sticking. 

How to Clean My RV Toilet With Vinegar and Baking Soda?

Combining vinegar and baking soda has always created a powerful toilet cleaner that leaves your toilet sparkling clean. However, when dealing with RV toilets, all products should be used sparingly. 

The first step is to empty the bowl if it is dirty by flushing it. Then, pour an amount of white vinegar into the bowl. The vinegar should be set to sit for a while so it can tackle the tough stains. Afterward, sprinkle some baking soda into the bowl. This combines with vinegar to give a deep clean. Finally, scrub the bowl with a toilet brush. 

Can You Use Vinegar to Clean the RV Toilet?

Yes, it is possible to use vinegar to clean your RV toilet. However, it is important to keep in mind that pouring the vinegar into the toilet might disrupt the good microbes and bacteria in the tank that prevent odors. Therefore, when it comes to using vinegar, just spray lightly into the bowl, and wipe it out or rinse. 

How to Clear a Clogged RV Toilet?

The last thing you need in your RV is a disgusting backed-up toilet. Several reasons can cause your RV toilet to be clogged, including a blocked line, a pyramid plug, or a tank clogged with compacted waste. 

To successfully unclog your toilet, you must first diagnose the problem. This way, you can know exactly what you are dealing with. For instance, if you have a pyramid plug, it is not possible to add much water to the tank.

Still, you can try opening the toilet valve and pouring an entire bottle of Unique Tank Cleaner into the toilet bowl. Some of these products will manage to seep through and open a channel into your tank. If this is successful, you can go ahead and pour as much water as possible. All this while, the black tank valve should be closed.

If it is a blockage in the line, you can try plunging it out first. If it does not work, you can pour a bottle of Tank cleaner into the bowl and let it sit overnight, then try plunging it again the next morning. A PEX pipe can also come in handy. 


RV toilet bowls are constructed differently from the ones at home. Usually, RV manufacturers are conscious of weight, and thus is the main consideration when choosing building materials. Home toilets are made of thick porcelain which is too heavy to be put in an RV. RVs may go for porcelain or more often, plastic. 

Basically, you can use anything you want to clean your RV toilet as long as it is done sparsely and you do not flush. You do not necessarily need a special RV toilet bowl cleaner. Still, if you wish to play it safe, you can go for a bowl cleaner that is made specifically for RVs. Bleach should be avoided at all costs, even if you do not use a holding tank treatment. 

The problem with chemicals is that they can potentially kill the good bacteria present in the tank. Although the exact quantity that can be used for all the microbes to die is still unclear, these harsh chemicals are not recommended. Ensure also that you do not flush the products at all. 


Cleaning the RV toilet bowl is neither complicated nor as straightforward as you think. The most important thing is to use the right products so that you do not damage the toilet and the holding tank. With that in mind, you can save yourself time and money trying to replace your toilet seat.
