All of us remember those days when our shower was new and it had a nice even flow of water to it. Those were the days and safe to say that all of us enjoyed these days to our core. Now, to be honest showerheads tend to lose their spark over time and we feel that they aren't giving the performance that we expect out of them anymore. This can be a major sign of worry.
However, the water flow loses its spark because of the fact that the showerhead now has particles stuck inside it. This can significantly alter the flow of water and may be the reason behind why the showerhead isn't performing the way it should. The best way to go about things here is to soak the showerhead in a plastic wrap of distilled vinegar.
