Caravan Toilet Cleaning and Maintenance
Beyond the tank chemicals, we carry Thetford bathroom cleaner, toilet bowl cleaner and grey water treatment. The seal lubricant is an important maintenance product as it keeps the blade seal on your cassette toilet functioning correctly. Using the right toilet paper helps avoid blockages in the cassette tank. For broader bathroom accessories including shower fittings, check our bathroom range.
If you are running a composting toilet instead, our Clesana and composting toilet accessories collections have the consumables you need.
Frequently Asked Questions
What is the difference between Aqua Kem Blue and Green?
Aqua Kem Blue is the original formula. Aqua Kem Green uses a more environmentally friendly formulation. Both are designed to break down waste and control odour in cassette toilet tanks.
How often should I add chemicals to my cassette toilet?
Add Aqua Kem to the waste tank each time you empty it, following the dosage instructions on the product. Aqua Rinse goes in the flush water tank and typically lasts a few days to a week depending on usage.
Do I need special toilet paper for a cassette toilet?
It is recommended. Standard household toilet paper can take longer to break down in a cassette tank. Thetford toilet paper is designed to dissolve quickly when used with cassette toilet chemicals.
