Hold bottle upright. Unscrew the cap a quarter turn. Fill the dosing chamber with the desired amount of cleaning concentrate (see scale) by squeezing the lower part of the bottle. Unscrew the cap completely and add the contents of the dosing unit to the windscreen water. 25 ml are sufficient for 2.5 litres of water. For larger containers use a correspondingly greater amount of concentrate. The bottle contents yield 25 litres of cleaning solution.
PLEASE NOTE: Protect against frost.
