When you first open the box, I was very happy about the smell of soap, incredibly fresh and lemony.
When cleaning the brush, I have this briefly dipped in lukewarm water and then I drove in circles through the soap until it foamed. Immediately, the color was stuck in the brush on the soap. I then already removed some dirt foam from the soap with the cleaned brush and am a few times driven by warm water until all the foam was gone. Then the brush were expressed slightly and laid out to dry. I have turned the brush once every few hours. The brushes were all clean and incredibly soft after cleaning. The leftover dirt on the soap I suppose at the end off with a tissue and then the soap is clean again. An unpleasant odor to the brushes I could not tell after cleaning but unfortunately was no longer present much of the citrus scent too.
