Keep your toilet clean and fresh with Duck Biodegradable Formula Toilet Bowl Cleaner. It comes in a bottle made with 35% plastic collected on land to prevent it from reaching the ocean, created in partnership with Plastic Bank. The biodegradable formula fights limescale, even under the rim. The toilet cleaner helps remove mineral deposits, toilet ring build-up and stains. It eliminates unpleasant odours and has a fresh, long-lasting coastal pine fragrance. The unique neck allows for better reach under the rim, evenly coating the toilet bowl. Just tip the bottle, direct liquid under the rim and squeeze it around the bowl. Brush above and below the water line, then flush. Size: 750ml.
