Clean waste-holding tank thoroughly

When using Berger Fresh Tank Cleaner, 100 ml of the cleaning liquid is mixed with 5 litres of water. The contents of the bottle are therefore sufficient for 3-4 cleaning processes. The bottle has a sight strip on the side for optimum dosing of the product and a cap with a child lock.

200 ml of Thetford Duo Tank Cleaner is mixed with 5 litres of water. The mixture should be left to soak for at least 16 hours before it can be emptied out again. The contents of the bottle are sufficient for four cleaning processes when dosed correctly. The bottle has a sight strip on the side to make dosing easier and a cap with a child lock. The liquid smells slightly of disinfectant when diluted, and the consistency is liquid. The product can also be used for cleaning the grey water tank.

After you have carefully cleaned the waste-holding tank, you should also take care of the toilet seal. This will prevent it from becoming porous and leaking and needing to be replaced. Here you can find out in detail how to do this. The seal care product from Thetford was specially developed for use on toilet seals. It is completely odourless and can be dosed correctly thanks to the small tube.

Here you can find all the cleaning products presented in this article in the Berger online shop.

First remove the waste-holding tank from the caravan or motorhome.

To remove the cap, turn the spout upwards.

Now pour the correct amount of cleaner into the tank. Follow the manufacturer's dosage instructions.

Then fill the tank with lukewarm water. 

Now close the lid and shake the waste-holding tank well.

Then empty the tank at a designated place. This can be the toilet at home or the disposal station at the campsite. Press the ventilation button while doing this.

Finally, fill the tank again with lukewarm water, shake it and empty it. Repeat this step until only clear water comes out of the waste-holding tank.

CamperClean, a fully automatic disposal station for toilet cassettes, is already available at over 400 campsites. A CamperClean machine empties and cleans the waste-holding tank completely without you having to touch it during the cleaning process. Then the cassette is filled with chemical-free sanitary concentrate. Cleaning your waste-holding tank in a CamperClean machine is therefore only suitable for thorough cleaning in between, but not before winter storage.
