Duck® Extra Power Foaming Bleach Gel better reaches under the toilet rim to get your toilet bowl clean. And it leaves the bowl white and bright, cleverly combining the benefits of bleach and the cleaning action of bubbly foam all in one toilet stain remover. Maybe not brilliant-scientist kind of clever, but, you know, for a bathroom cleaner, this is pretty smart. Top marks kind of smart. Anyway, using the uniquely shaped neck, squeeze the liquid evenly all around the inner rim of the toilet bowl. Brush above and below the water line. Then flush, leaving behind a sparkling toilet with a wonderful Marine scent.
