Remove toilet cistern lid. Take the bottle from the box carefully as some powder residue may spill from the bottle. Tie the plastic wire tie by pulling it through the hole at the top side of the bottle and tying that end. Immerse the bottle in the water up to the waterline as marked. Do not allow the bottle to be fully submerged. Bend the tie over the side of the cistern to hold the bottle in place and replace the cistern lid. Do not use in toilets with cracked or damaged toilet bowls. When replacing, empty remaining liquid into the cistern before removing bottle.
Storage Instructions: Store in a cool, dry place.
