Product details

Green from inside and outside Removes odours and keeps tank and pipes clean
Microbiological Biodegradable harmless to humans, animals and the environment
Bottle made from recycled materials Without aggressive chemicals

Product description

ECO CLEAN liquids are free of aggressive chemicals and instead use natural micro-organisms. These decompose the pollution and release odorless substances such as water and air.

Microbiological waste water tank additive for caravans, motor homes and boats. Highly effective concentrate with natural microorganisms, free of chlorine or aggressive chemicals. Used regularly, it eliminates unpleasant odors from drains, keeps tank and pipes clean, prevents dirt and grease deposits and ensures trouble-free emptying of the tank. Particularly gentle on materials, it contributes to the longevity of graywater tanks and pipelines.

Application:
Shake well before use, add 20 ml ECO CLEAN wastewater additive per 20 liters of tank capacity directly into the sink and shower drains. For optimum results, divide the dosing quantity between the drains. Re-dose as needed.

Full test report
Seit wann nutzt du Berger Eco Clean Grauwassertankzusatz?
„We have been using the add-on for about 2 weeks.“
Bei welchen Außentemperaturen fand der Test statt?
„During our vacation, it was between 30 and 33 degrees throughout.“
Hand holding white plastic bottle with green and white label against a background of trees and vehicle
Hand holding a bottle of cleaning foam above a sink
Very good
Wie war der erste Eindruck der Sanitärflüssigkeit?
„The gray water tank additive is conveniently filled and the bottle is attractively designed.“
Very good
Wie beurteilst du den Geruch des Produktes?
„The additive smells pleasant and not chemical. As the product is poured into the caravan sink and then rinsed off, you only smell it when you pour it in.“
Average
Wie leicht lässt sich das Konzentrat dosieren?
„As you only need a small amount of concentrate for one use, dosing is not so easy at first. Unfortunately, the dosage markings on the bottle do not go up to the level of the liquid. Once the bottle is a little emptier, however, it is very easy.“
Very good
Wie gut wurden die Gerüche im Abwassertank während des Tests absorbiert?
„During our test, the water in the waste water tank was odorless and it foamed significantly less than without the additive.“
Very good
Wie lange hat der Inhalt der Flasche gehalten?
„The contents of the bottle last a long time as large quantities are not required.“
Würdest du das Berger Eco Clean Grauwassertankzusatz nach dem Test weiter nutzen?
„We will continue to use the gray water tank additive, as we have not had any problems with unpleasant odors from the wastewater pipes in the past.“
Dein Gesamteindruck vom Berger Eco Clean Grauwassertankzusatz
„The additive is conveniently bottled and the bottle is attractively designed. The smell is pleasant. We had no problems with unpleasant odors - even at high outside temperatures.“
Overall impression:
„The additive is conveniently bottled and the bottle is attractively designed. The smell is pleasant. We had no problems with unpleasant odors - even at high outside temperatures.“

Good
Wie beurteilst du den Geruch des Produktes?
„Pleasant to almost neutral.“

Good
