Definitely cleans the soap the brush, when you scrub around with the brush on the soap.
Hmmm .... I'm having not sure if the shampoo has not met the same purpose or the brush has cleaned even better?
In my expensive brush I do not want umherschrubben on the soap so that they are clean and in the middle, but am now but again Brush Cleaning Spray for more favorable I'll continue the soap until it is depleted.
