If the water stream from your showerhead is not as strong as it once was, it may not be the water pressure. Over time, minerals in hard water (calcium, limescale and rust) build up in the pores of your showerhead and either clog the pore completely or limit the stream of water to a trickle. It’s time to clean your showerhead! CLR Calcium, Limescale and Rust Remover can dissolve these build up issues, turning the power of your shower back on.
