Key features & specs

How it compares

Carbona tablets sit between basic bleach tablets and premium plant-based brands like Seventh Generation. They use enzymes (similar to laundry stain removers) that break down organic matter, offering a unique mechanism compared to chlorine or oxygen bleach. They are less expensive than Seventh Generation but more durable than generic store brands.

How to use it

1. Place one tablet in the toilet tank, ensuring it does not contact moving parts.
2. Allow 20 minutes before flushing to initiate enzyme activation.
3. Each tablet lasts up to 10 days depending on water usage.
4. Replace when the green tint fades completely.
5. For best results, use a toilet brush weekly to remove loosened debris.
6. Store in a cool, dry place to preserve enzyme activity.
