Empty the waste-holding tank (toilet waste tank) when it is full or starts to smell (4 to 5 days for Thetford Blue products, 3 to 4 days for Thetford Green products), use Thetford Aqua Soft quick dissolving toilet paper to prevent clogging. Regularly clean the outside of the toilet with Thetford Bathroom Cleaner and clean the toilet bowl with Thetford Toilet Bowl Cleaner when necessary. Finally, clean the waste-holding tank and grey water tank (tank that collects waste water from sink and shower) with Duo Tank Cleaner Concentrated 2-3 times a year to keep all moving parts inside the tank at peak operational level and to prevent odour formation during winter storage.

Depending on user behaviour, we recommend replacement after 4-6 years.
