Did you know that traditional toilet cleaner cages can harbour germs? Duck® Fresh Discs Toilet Cleaner Discs have a gel based formula that self-sticks to the toilet bowl so germy cages aren’t something to fret about. Fret about other things instead. Like crocodiles. It’s hard not to worry about things that want to eat you, you know? Anyhow, my Fresh Discs prevent the build up of limescale and stains that harbour germs. Just stick it to the inside rim of the toilet bowl so you can keep things clean. Pretty easy, huh?
