A powerful acidic toilet cleaner designed to descale, deodorise and disinfect. The thick, blue, pine-fragranced formula clings to the toilet bowl and deodorises by removing scale and killing bacteria, attacking scale and organics even below the waterline. NB. Not suitable for use on stainless steel. Ideal for use to remove severe scale and staining from toilets and urinals, ZAKOL can also be used to remove algae and slime from walls, patios and paths. To clean ceramic W.C. bowls and urinals: Apply ZAKOL undiluted to the surface and allow 5 minutes contact time. Agitate heavily stained areas with a toilet brush and then flush the toilet or urinal. Use biocides safely. Always read the label and product information before use
