If you own a campervan or a motorhome, you will no doubt be aware of some of the funny smells that can come from the toilet, especially when it hasn’t been emptied for a couple of days, and even worse in the hot weather!
These smells are just not what you want when you’re travelling and living in such a small space. This is where motorhome toilet chemicals come into play.
Maintaining cleanliness and hygiene in your motorhome, especially in the toilet area, can make a significant difference to your on-the-road living experience. Among the most crucial aspects of this upkeep is the use of motorhome toilet chemicals. But what exactly are these, and which ones are the best in the market? Let’s find out!

Introduction to Motorhome Toilet Chemicals
These chemicals serve two main functions – to break down waste and toilet paper in the waste tank and to minimise odours. They are designed specifically for use in motorhomes, campervans and caravans, providing a critical function in maintaining a clean and odour-free toilet system.
The Importance of Motorhome Toilet Chemicals
You might be asking, “Why can’t I just use regular cleaning products?” The answer lies in the complexity of the motorhome waste system. Ordinary cleaning products may not effectively dissolve waste or control the smell. Even more, they might damage the seals and moving parts of the toilet system, leading to more costly repairs.
Factors to Consider When Choosing Motorhome Toilet Chemicals
When selecting the best motorhome toilet chemicals, consider their efficiency in breaking down waste, odour control, safety for the environment, compatibility with your motorhome’s system, and of course, price.
Below we’ll list some of our favourite products that we’ve tried and tested.

How to Use Motorhome Toilet Chemicals Safely
Always follow the instructions on the packaging. Use gloves and avoid contact with skin and eyes. Dispose of the waste at approved facilities such as campsites or waste disposal points.
Do not empty chemical waste into nature or undesignated spots as this can be really dangerous for the environment. Not only that, it gives other van lifers a bad name. If we all dispose of our waste correctly, we can all continue to enjoy van life responsibly.

I love everything about travel, from seeing new places, learning about new cultures and trying new foods! I believe that travel is one of the best forms of education you can get, I have learnt so much about myself and about the world from travelling all over. Travel is something I feel so passionately about, and I love the fact that we are now lucky enough to have this opportunity to do what we love as much as we can, it’s a dream come true.
Before we started travelling, I worked in local government in administration. I had been in this job for several years and had reached a complete brick wall where I was so fed up, but didn’t know what else to do. The only thing I knew that I wanted to do was to travel, and had wanted to do that for many years.
There were hundreds and hundreds of places on my wishlist that I wanted to go to, and I knew that going on a weeks holiday maybe twice a year if we were lucky wasn’t going to cut it.
After being in lockdown due to the Covid pandemic, and working from home staring at the same 4 walls every day, 2021 seemed like the perfect time for us to take the risk to finally do what we had dreamed of for so long.
It was a hard decision to completely change our lives, but so far it has been the best decision we have ever made!
