Aloha all, Our bathtub is running slow and my husband brought home a product made by drano. It's a foaming product. The bottle looks very strange. It is split into two parts but the mouth of the bottle is open to both halves of the bottle so that when pouring it, the liquid will mix together. I suspect that's when it will start foaming. The only warning is to not use it in a toilet. Anyone had any experience with this stuff? Betsy
