Buying Guide
How to choose the right blue loo block for your bathroom:
- Cleaning scope: If you want tank and bowl cleaning plus deodorizing, consider tablets designed for both tank and bowl action.
- Longevity: Look at tablet lifespan per flush to estimate monthly replacement needs.
- Limescale prevention: If you have hard water, opt for blocks with limescale prevention and strong foaming action.
- Fragrance vs. fragrance-free: Decide whether you prefer a noticeable scent or a milder option integrated with cleaning.
- Bulk vs. occasional use: For larger homes, a bulk pack can reduce reordering frequency, while smaller packs suit single bathrooms.
- Installation and safety: Ensure you place blocks according to guidance and avoid tearing outer films unless specified.

- Place blocks in the toilet tank as directed and let them dissolve before flushing for optimal release of cleaning agents.
- Rotate blocks if you maintain more than one bathroom to minimize odors across rooms.
