Royal Flush,Biological Cistern Blocks (Keg 24 x 50g.Blocks)

Royal Flush blue cistern blocks deliver both biological and chemical cleaning agents as well as a blue colour each time the flush is activated. The water-softening and sequestering agents maintain a clean bowl while the biological cleaning power works in the pipes to prevent any build-up of solids and continues working in small bore, pumped toilet systems and older buildings where drain-runs can be problematic. Also enhances septic tank efficiency.
