Once the cloth has been left sitting on the tap for an hour, the cleaning pros advised using the same cloth to wipe away the limescale.
They added: “If the limescale around the spout still won’t come away completely, cut a lemon in half and screw it onto the spout until it stays in place.
“Leave for another hour and then rinse and scrub away the remaining scale.
“Use a scouring pad on tough limescale but only on the underside of the spout as it may scratch the finish on the faucet itself.”
