I fell back on an old faded brush scraping tiles and aspired nothing, and I have bothered me under the mocking gaze of my wife who savored with relish her victory and her newfound superiority, which it uses Never brush but simply the pipe, despicable practice that I refuse to give in completely.
And then search the internet gave me the smile of course, "my" triangular brush could be replaced by a strictly identical model!
Fair price, fast shipping, satisfaction guaranteed: since I am a happy man, and on this subject there, finished the smirks.
