Buying Guide


The main purpose of having an RV is to drive freely and camp wherever you want. Hence, an RV toilet is a great option because they bring more comfort. But they do need proper cleaning. Therefore, we’ve created a buying guide that describes the most important features the best RV toilet chemicals must have.  

Check for products that clean both black and gray tanks

At home, you clean your bathroom with several products that remove dirt and prevent bacteria growth. RV toilets don’t differ much because they need proper cleaning and handling of their water tanks.  

Generally, RV’s are equipped with two water tanks, a black and a gray one. Gray water represents the water you use in your RV, except for what you use to flush the toilet. That one is called black water. The water that you use for showering, cooking or washing dishes goes in the gray tank.

There are many products available for sale that clean both gray and water tanks. It’s more convenient and efficient to purchase a cleaner instead of two.  

If you don’t add a gray water tank treatment chemical, you might notice that the tank will start to release a bad odor. These cleaning chemicals are mandatory because they keep your valves from getting clogged. Plus, the waste is released more easily.


Tablet or liquid

The best RV toilet chemicals for breaking down waste typically come in two forms, tablets or liquids. No matter what you choose, they are both extremely effective at cleaning your RV toilet and removing dirt.  

You should choose depending on your own level of comfortability and practicality. If you’ve used tablets in the past, you should stick to them. The same rule applies to liquids. Essentially, these options do the same thing but have different usage.  

Tablets are more convenient because you just add a tab to the water tank without having to worry about spilling or adding too much quantity.   

On the other hand, liquid tank chemical treatments can be easily flushed down the toilet. Also, you can purchase them in bulk which means they last longer.  


Buy in bulk  

In your search for the best RV toilet deodorizer think of practicality. When you and your family are on the road, you probably don’t have many shopping occasions. Therefore, it is advisable to purchase larger quantities of toilet chemicals so that you don’t run out of them when you need them most.  


Stay away from formaldehyde

In recent years, there’s been an impressive amount of negative reviews towards cleaning products that contain formaldehyde. This type of tank treatments contains strong chemicals that kill bacteria but also cause massive problems to the natural fauna.  

Black water tanks are emptied in the leach field of the RV parks. This means that harmful chemicals are released into the natural environment and damage the soil and the water.  

Therefore, look for formaldehyde-free and eco-friendly product options that clean your toilet quite good and protect the world we live in.
