Let’s show you how to choose the best chemicals for your portable toilet.

Do I need to use chemicals in my portable toilet?
It is essential to use chemicals in your portable toilet to ensure that the waste is treated correctly and to ultimately minimise any odors. With such a small toilet, usually also in close proximity to its users, you don’t want to have a smelly toilet.
Chemicals help with the rinsing process, keeping the main bowl as clean as possible, whilst others help with the waste.
If you are only planning on using the toilet overnight for example, then simply empyting it the next day would be perfectly ok.
Is it ok to use normal household chemicals in a portable toilet?
Whilst some household chemicals are ok for cleaning the external parts of the toilet, it’s not considered a good idea for other cleaning activities. Household cleaners are not made with toilet waste in mind. Using these on a new portable toilet could also breach the warranty.
Where can I empty a portable toilet?
Portable toilet waste should only ever be emptied in places where you are authorised to do so and are clearly signed. It is never acceptable to empty waste in the woods, in drains and in toilets used by people (eg caravan parks) as a general rule.
Some campsite owners will allow for empyting of waste in their facility blocks but this should only be done if you ask, or it is signed. Do not do it otherwise.
Don’t ever empty them into compostable toilets either. These must remain chemical-free for them to work as designed.
Chemicals for the flush tank
Adding chemicals into the flush tank help to keep it all clean, assists with waste degradation, lubricates the seals and it make it all smell a little better too.
These chemicals should be able to be used in a septic tank.
Chemicals for the waste tank
Given this is what you will actually eventually dispose of, the more eco-friendly you can be here with what you put in your tanks, the better.
It is not recommended to use anything with formaldehyde in it at all which is considered to be highly toxic.
Also, check to see if your chemicals are safe to use in septic toilets. Septic tanks are widespread in America so sooner or later you will need to empty your waste into a septic system.
Types of chemicals for portable toilets
The most basic form are liquids which are simply added to flush tanks to waste tanks.
Sachets and tablets are also used and are very convenient to store and use. No water is needed to mix as is the case with the liquid, you simply pop the tablet or sachet into the relevant tank.
Which toilet paper should be used in a portable toilet?
You should only ever use the toilet paper that has been specially designed for use in a chemical toilet. Whilst technically you can, the correct answer is you shouldn’t.
Regular toilet paper is thicker, not designed for quick degradation and as a result, will take longer to break down in your waste tank and occupy more volume in the tank, meaning you will need to empty more often.
