Vicky Murden said: “Black Harpic is magical, it works instantly if the limescale isn’t too stubborn, can also be left overnight.”
Harpic Power Plus Toilet Cleaner Gel can remove limescale, tough stains, ruse as well as dirt build up.
What’s more, it gets rid of 99.9 percent of germs too.
It can be picked up for as little as £1 in supermarkets as well as retailers like B&M.
