How do I properly clean a composting toilet?

Anyone who uses a composting toilet will sooner or later ask themselves:
How do I clean them effectively – without chemicals and without damaging the materials?
Here you will find the most important tips and no-gos for a clean, long-lasting composting toilet.

1. Water is your best friend

Urine and feces consist largely of water-soluble components .
For daily cleaning, it is often sufficient:

• clear water
• a damp cloth
• or some mild soapy water

In everyday life, you often don’t need more – less is more here.

⚠️ 2. No vinegar cleaner!

Even though vinegar cleaner works naturally:
❌ Please do not use if you have a silicone odor trap.
The acetic acid attacks the material and can make the valve brittle or leaky.

🍋 3. Better: citric acid

If you want to remove stubborn deposits (e.g. urine stones), citric acid is a better choice.
It has a descaling, antibacterial effect and is gentler on silicone and plastics .

It is best to dissolve it in warm water and apply it with a spray bottle.

🧴 4. Disinfection – but properly

For occasional disinfection (e.g., after storage or heavy use), you can use an alcohol-water mixture —e.g., isopropanol or ethanol diluted with water.

Good to know:
Our divider insert is resistant to alcohol and diluted acids , so you can easily clean it with it without damaging the material.
