The shower in one of my bathrooms has just about run its course, so I'm thinking of replacing it soon. Unfortunately, one issue we've been having with it is that some kind of mold seems to have set up between the wall of the shower, and the wall of the bathroom. We tried bleaching it before putting the current shower in place, but it seems we missed some of it or something, and the mold has even grown through the antifungal caulking we used to seal it. Any recommendations for getting rid of it (the lower the cost, the better) would be greatly appreciated via /r/DIY http://bit.ly/2EhJdUi
