Royal Flush Non-Bio Cistern Blocks

Royal Flush Non-Bio Cistern Blocks clean and freshen the toilet bowl with each flush.

Cleaning and freshening through the flush water

Directions for Use

Check the toilet and prepare

Check that the toilet manufacturer permits in-cistern blocks. Close the toilet bowl lid, carefully remove the cistern lid and flush to empty the cistern before positioning the block.

Place the wrapped block

Leave the soluble wrapper in place. Put the block inside the cistern away from the water inlet, then replace the cistern lid. The wrapper dissolves in water as the block begins to work.

Monitor during cleaning

Check the flush-water colour during routine washroom care. Replace the block when the colour fades, and continue cleaning the bowl, seat and surrounding surfaces according to your normal schedule.

Keep spare blocks protected

Store unused blocks in their original container in a cool, dry place. Close the lid firmly after taking out a block and keep the container out of children’s reach. Follow the pack’s handling instructions.

Biological Urinal Blocks
Biological Urinal Blocks

Biological urinal blocks help keep commercial urinals fresh by treating the organic deposits that collect in traps and pipework. As each blue block dissolves, it releases beneficial bacteria, cleaning agents and a citrus fragrance. The bacteria produce enzymes that break down organic matter where persistent urine odours often begin, helping facilities teams maintain the pipework as well as the visible fixture. The loose blocks suit individual bowls and long trough urinals in pubs, sports grounds, schools and public washrooms. Their water-soluble format makes it easy to replenish heavily used fixtures individually. For sites managing water consumption, they can also support a reduced flushing programme suited to the installation.
