Yeah I don't think this is such a great brush
It is sturdy but when I try to clean the bottom of my stainless steel pitcher of the chocolate at the bottom I can see clearly it is not coming up-not cleaning it. So in the end it is not sturdy enough. If you are trying to clean bottles it is probably not doing much to clean it. I would put something colorful to see if it is working. Mine did not really work. Uggghhh! I need a regular strong bristle brush.
