Use:
• Hang the Domestos Toilet Block on the edge of the toilet, ensuring it is in the direction of water flow.
• If the water doesn't pass through the block when you flush, hang the block somewhere else on the side of the toilet so that it's in the direction of the water flow.
• Once the product is finished, remove the cage from its place next to the toilet and throw it in the trash can.
• Then install a new Domestos Toilet Block.
• Wash your hands after contact.
