4. Now it is time for a two-step rinsing with the easy clean oil set.
Step 1: to clean the drinking water tank residue-free, put easy clean oil absorb (ratio 1:10) into the water tank and fill it completely with water. You can also fill the tank alternatingly with easy clean oil absorb and water to get a better mix. After one hour empty the water tank and dispose of the mixture according to official regulations. Thoroughly rinse the tank three times with clear water.
Step 2: use easy clean Comp. 1 and easy clean Comp. 2 (ratio 3:50) to disinfect and clean thoroughly the water tank. Add both cleaning agents to the drinking water tank and fill it completely with water OR you can give easy clean Comp. 1 and Comp. 2 in the half-full drinking water tank and fill it then completely with water. After one hour empty the water tank and rinse thoroughly two times with clear water.
