Product description

ECO CLEAN liquids are free of aggressive chemicals and instead use natural microorganisms. These decompose the contamination, releasing odorless substances such as water and air.

For use in mobile homes/cars, boats, buses, trains, airplanes and trucks, as well as pit toilets. Highly effective concentrate of enzymes and microorganisms for the decomposition of commercially available sanitary paper and the elimination of unpleasant odors. The contents of the tank can be disposed of in the toilet.

Application:
Shake well before use.
  • Portable toilets (up to 20 l tank capacity): Add 50 ml ECO CLEAN toilet additive to the tank, add water until the bottom is covered.
  • Larger tanks: Adjust dosage accordingly and add approx. 5 l of water.
Attention: If other additives have been used so far, up to 6 applications are necessary until the microorganisms work efficiently and odors disappear completely.

Wie lange nutzt du das Berger Eco Clean Toilettenzusatz für den Fäkalientank schon?
„During our last vacation, we were able to test the add-on for 2 weeks.“
Wurde das Berger Berger Eco Clean Toilettenzusatz für die mobile Toilette oder für die Kassettentoilette verwendet?
„In our caravan, we use the additive for the waste tank in a cassette toilet“
Bei welchen Außentemperaturen fand der Test statt?
„It was between 30 and 33 degrees throughout“
Person handling a gray pipe on the outside of a house
Hand holding a bottle with green and white label and dropper cap in front of a background with trees and a white vehicle
Very good
Wie war der erste Eindruck der Sanitärflüssigkeit?
„The sanitary liquid comes in a handy bottle and is attractively designed. The pleasant smell is immediately noticeable“
Very good
Wie beurteilst du den Geruch des Produktes?
„The liquid smells very pleasant and not chemical. After using the toilet, the chemical smell hung in the air when using other additives. This is not the case with this product. You can hardly smell the toilet additive.“
Average
Wie leicht lässt sich das Konzentrat dosieren?
„As you only need a small amount to fill the faeces tank, dosing is not so easy. Unfortunately, the dosage markings on the bottle do not go up to the level of the liquid. This makes dosing very difficult, especially at the beginning, and there is a tendency to overdose. Once the bottle is empty, however, it is very easy.“
Very good
Wie gut wurden die Gerüche während des Tests absorbiert?
„We were impressed by how well the odors are absorbed with so little liquid. We only use the toilet in the caravan a little, so the waste tank rarely needs to be emptied. Despite the high temperatures, the sanitary liquid did a great job and nothing smelled.“
Very good
Wie lange hat der Inhalt der Flasche gehalten?
„The contents of the bottle last a long time due to the economical dosage.“
Very good
Würdest du das Berger Eco Clean Toilettenzusatz für den Fäkalientank nach dem Test weiter nutzen?
„In any case, we would like to continue using the additive. The environmental compatibility, the good smell and the good absorption of odors have convinced us.“
Dein Gesamteindruck vom Berger Eco Clean Toilettenzusatz für den Fäkalientank
„The liquid is filled in a handy bottle. The product works reliably and absorbs unpleasant odors very well - even at high outside temperatures.“
Overall impression:
„The liquid is filled in a handy bottle. The product works reliably and absorbs unpleasant odors very well - even at high outside temperatures.“
