Royal Flush Non-Bio Cistern Blocks
Royal Flush Non-Bio Cistern Blocks clean and freshen the toilet bowl with each flush. Made by Bio-Productions, this non-biological formulation combines a light fragrance with scale inhibitors to help limit new limescale deposits. The blue flush water adds a visible sign of freshness and fades as the block is used up.
Cleaning and freshening through the flush water
The block releases cleaning ingredients and a light fragrance into the cistern water. Each flush carries the treatment into the toilet bowl, providing ongoing freshening between routine cleans.
Scale inhibition and a visible replacement indicator
Scale inhibitors help limit new limescale deposits during use. The blue colour of the flush water gradually fades, providing a convenient indication that the block needs replacing.

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.
