Limescale, calcium, rust stains and other mineral deposits may build up over time causing air flow and water flow to diminish over time. Apply as needed. Spray directly onto buildup and allow to remain on surface for 5-10 minutes. Rinse thoroughly with clean water. For stubborn buildup, reapply or soak. No need to use heavy scrubbing with scouring pads, which can harm surface finishes.
