2 x 50 gram sachets
AquaSPArkle Immerse is a top quality powdered filter cleaner that removes oils, grease, rust and, particularly, scale from hot tub filter cartridges.
Immerse is a rapidly soluble formula that may be used in a Filter Soak Container or the dishwasher.
Use two sachets per 18 litres of water, ensure that the cartridge is completely immersed and soak overnight. Alternatively, use half a sachet in your dishwasher.
For best results allow cartridge to dry before re-installing.
