Materials Needed:

Protective mask (optional)
Freshwater hose or bucket

Toilet brush or tank cleaning wand (optional)
Step-by-Step Guide:
1. Prepare for Cleaning your Thetford Toilet Casstette
Safety first: Put on rubber gloves and a mask (optional) to avoid contact with waste or unpleasant smells.
Locate the waste disposal cap: The waste tank typically has a cap at the bottom for emptying. You'll want to be near a proper waste disposal site (dump station) for this task.
2. Empty the Tank
Position the thetford toilet cassette above the dumping site or toilet and carefully open the waste valve to drain the contents. Make sure to fully empty the tank.
If your tank has a freshwater rinse option, run clean water through the tank to help flush out any residual waste.
3. Rinse the Tank
Use a hose with a spray nozzle, or a large bucket of water, to rinse out the inside of the tank. Aim the water at the inside walls to loosen any remaining waste.
If your Thetford model has a flushing nozzle or a tank cleaning wand, use it to thoroughly rinse the inside.
4. Clean the Tank
Using a cleaner: You can use a specialised Thetford waste tank cleaner or an eco-friendly tank cleaner. Follow the instructions on the product label.
DIY solution: If you don’t have a commercial cleaner, you can make a cleaning solution using:
1 part white vinegar and 2 parts water, or
25g of baking soda mixed with water.
Pour the cleaner into the waste tank (about 1/4 to 1/2 of the tank’s capacity).
Swirl the solution around by gently shaking or tipping the tank, ensuring the cleaner contacts all internal surfaces.
5. Scrub the Tank (Optional)
If the tank is particularly dirty, use a toilet brush or a tank cleaning wand with soft bristles to scrub the inside. Be gentle to avoid damaging the tank's material.
6. Rinse Again
After cleaning, rinse the tank thoroughly with clean water to remove all cleaning solution and residue.
7. Dry and Store
Allow the tank to air dry before storing it. If you're storing it for a while, keep the tank lid open (in a safe place) to prevent mildew or mold buildup.
8. Disinfect the Exterior
Wipe down the outside of the waste tank with a disinfecting wipe or a diluted bleach solution to kill any lingering germs and bacteria.
9. Reapply Treatment
Once the tank is dry and clean, consider adding a tank deodorizer or holding tank treatment to help prevent odors and break down waste during future use. Thetford offers several options, including liquids or tablets.
Tips:
Always clean the tank regularly to prevent buildup and odors. Ideally, clean it after each use or once a week if you're using the toilet frequently.
If you travel with your caravan/motorhome or portable toilet frequently, try to clean and disinfect the tank at least once a month, depending on usage.
Avoid using harsh chemicals like bleach or ammonia unless you're sure they’re safe for your particular model and materials. Check the manufacturer’s recommendations.
By following these steps, your Thetford waste tank should stay clean, odor-free, and in good working condition!
