Toilet Blue (Pack of 6)
No need to remove the pleated wrapper as this will dissolve in the water.
Gently drop the block into the cistern at the opposite end to the water inlet, by the float
Allow 5 minutes for the block to settle before flushing.
For best results clean the toilet thoroughly to remove existing limescale deposits.
Replace with a new Clean Zone cistern block as soon as the colour fades.
