Harpic Power Plus Deep Clean Tabs cleans the toilet below the waterline and all the way into the U-bend, without the need to scrub.

Directions:

Before applying the tablet, flush the toilet to ensure there is no water in the bowl, which will allow the tablet to work effectively. If there is any visible dirt or debris in the toilet bowl, it may be helpful to give it a quick rinse with a toilet brush to ensure the tablet can clean properly. Drop one Harpic Power Plus toilet tablet directly into the toilet bowl, ideally under the rim, where the water flows. Let the tablet dissolve and release its cleaning solution into the water. The tablet will begin to fizz and start breaking down the limescale and any stains present in the toilet bowl. The tablet will work to remove 100% limescale, and you do not need to scrub it, as it will clean and freshen automatically.
