The dosing system is really designed WELL: a firm and continuous pressure on the bottle automatically dispenses the correct dose of product in your bucket of 5 liters.
Caution however with the use of pure product on a sponge: it is necessary to go slowly, otherwise the rinse can be problematic (welcome to hell foam ;-))
VERY POSITIVE POINT: The synthetic fragrance (unidentifiable) is very discreet and quickly fades .. great when you do not want to live in a saturated atmosphere of more or less doubtful chemical fragrances.
In conclusion: A multi-surface cleaner, concentrated, with a discreet scent: FINALLY!
