The water is high in silica (90 mg/L) and leaves silica stains (for want of a better word) on shower screens, car windows, car bodies, etc. Is there a product available that removes the silica. I would assume some form of acid. We have tried "Alu-Clean" but you still need to scrub rather hard and it doesn't remove it all.

General description Silicon dioxide (SiO 2) exists in three crystalline forms, namely quartz, tridymite and cristobalite.It reacts with hydrofluoric acid to form silicon tetrafluoride (SiF 4) and water. Silicates are formed on reacting SiO 2 with alkali melts. SiO 2 is the main component in glass, brick and concrete and also forms the insulator in silicon devices.

However, the reduction in the silica content after acid wash could be because of the dissolution of the silica along with other debris during acid wash. XRD analysis has also shown that there is about 2.61% of Fe in the sand sample obtained after water wash and that in the acid wash sample is about 2.16%. This indicates the iron
