I was looking at a interior repaint job that a friend was working on and one of his guys was cleaning the brushes like this but in the customers sink I was thinking what the heck this has to be so unprofessional right or is just me? Thanks Chris your videos are always such a blessing. Well I would say we have done it. If there is not other place then so be it. However, we clean the sink when done cleaner then before we started.
