Wear rubber gloves and get stuck in to properly clean a toilet
To remove hard water and limescale toilet stains, wear rubber gloves, flush the cistern and remove a mugful of water from the bowl – I use a tin mug – so you can see the rim of the limescale line clearly. While the water level is low, pour or spray the loo cleaner around the limescale in the bowl. Make sure you get the product around the top and where water drips down the back of the bowl too. Leave for 30 minutes ( or according to the product instructions), then rub with a fine scourer or brush. Pour the water in mug back into bowl, then brush and flush the cistern again.
