Hot Spring Freshwater Stain & Scale Defence will prevent and/or remove scale deposits caused by mineral precipitation which can build up rapidly on hot tub surfaces due to relativley high water temperatures and imabaanced PH.
Apply this product directly to your hot tub water whilst the pumps are turned on to aid distribution
Hot Tubs treated for heavy scale may require cartridges to be cleaned a few days to a week after treatment
When hot tub water becomes saturated with dissolved solids (TDS) then Stain & Scale Defence becomes less effective. At this stage, you should change your hot tub water and use a flush to clean the pipes.
