For the greywater tank, dispense 600 ml into the empty greywater tank through the sink or in the shower, add 50 liters of warm water. Feel free to drive the boat for at least 1 hour so that the liquid can act throughout the tank. When you empty the greywater tank after 16 hours, deposits, coatings and bad smells are gone.

For the waste tank, dispense 200 ml of Duo Tank Cleaner Concentrated into the empty tank, add 5 liters of warm water and shake the tank thoroughly. Carefully ventilate the built-up pressure in the tank before opening the lid. You can also run the boat for a while when the Duo Tank Cleaner Concentrated is in the tank, so the cleaning is improved. When you empty your waste tank after 16 hours, deposits, coatings and bad smells are gone.
