Toilet Cleaner Macerator Descaler can be used as a daily toilet cleaner or every 1-3 months as a descaling treatment. It keeps toilets clean and berry fresh, as well as prolonging the life of macerator systems. Use in any toilet, internal or external macerator pumps and urinals. Our formula breaks down limescale, cleans and removes dirt and grime safely and effectively without disrupting septic tanks or macerator saniflo seals. Use around the toilet bowl for every day, general cleaning. Or for macerator descaling, disconnect the macerator unit from the electric supply. Pour 1-2.5 Litres into the toilet bowl. Turn on the macerator unit again for a few seconds to allow the descaler to enter the system. Turn the macerator off and leave to work for up to 2 hours. The solution can be left in the system to descale over night for very heavy scale build up. After descaling, reconnect the power supply and flush toilet to rinse. For hard water areas descale monthly. For soft water areas descale every 3 months.
